I've got my 4.10's on the way(swapping out 3.73's) Now, I'm thinking about going from a 280 to a 292 Comp Magnum cam on my 396. I have a Performer 2-O w/ 750 vac. secondaries. After the cam I'll do the 750 DP and Perf.RPM. What do you think Racer 1320?

Nobody seems to like the Performer 2.0 around here. Makes me feel bad for putting one on my car.

Crane F304-2. Off the shelf on the 114 LSA if you want a nice idle and smooth power band or that grind on a 108 LSA if you dont mind big lope and want an earlier torque curve peak.

Jim, I don't like the cam you have now and definitely wouldn't recommend the 292. First it is too big and second there are far better grinds available today than that 20 year old piece.

Your Performer 2-0 isn't terrible except that the ports are cast for the small peanut port ovals and need to be opened up to the larger oval ports.

As you probably know I'm big on the HP Series Holley's but a standard 750 or Q-jet will get the job done.

Why change to 4.10's? Tell us what it is your trying to accomplish and how you intend to use your car. Give us the complete combo.

Racer, I do drive it on the street but, I really need to start running it at the track. To this end I sold my old trailer and bought a new one with a dovetail(18ft.). I'm not really concerned with great street manners as I don't put many miles on it anyways.

The 4.10's are coming for two reasons 1. Everyone I know of that runs their Chevelle regularly does so with 4.10's. 2. I run a 28X12.5X15 Sportsman Pro Tire, I like the looks of those big meats but, they are tall and when they hook-up they the car does'nt accelarate like I want it to.

The HP is nice but out of my reach. I like Q-jets on my truck.

This engine(66 396) was assembled when I bought the car a few years ago and runs good. From what I can tell it has the factory type dome pistons,I was told a .525 lift crane cam,I know it has roller rockers,750 vac. secondaries,perf 2-O,Hei w/super coil,headers,and a TH350 w/2400 stall. I only suggested this cam as a compromise of price and what I thought you recommended a while back to BB_Mike......and a nice choppy idle would'nt hurt either.

Jim, a 396/402 with the cam (Ultradyne 280/288 Hydraulic ground on a 110LSA) that I recommended for BB_Mike combined with a turbo 400, the right converter (ATI 10" 408360) and 3.73 gears is good for mid to low 12's in a typical street/strip chevelle weighing upwards of 4000 lbs. Of course there is more to it than just a cam swap, like using the right heads and having them prepared properly but it's still a VERY streeatable, drive anywhere combo that isn't to expensive to build. In addition the heads, intake, carb, headers and converter can be used if you ever step up to a 454 or 502 based combo. Just some thoughts.

If it's the strip we're talking here, I can't beleive a solid cam hasn't been mentioned. How about a 282S from Comp or something similar? A nice 3500 conveter and single plane manifold will rock that 70! Especially with the new 4.10's

I do not recommend asking the cam company for a cam choice. They seem to be in a competition to sell cams and know that most buyers want to hear they need a big stick. Most cam companies I spoke with will recommend a cam much larger than needed to do the job. I believe a local machine shop/engine builder can be of better service in selecting a cam as they have nothing to gain. I suppose it goes back to the marketing and bigger is better mentality.

This is about the only time I don't call a manufacturer for advise.

Jimmy a solid wasn't mention by me because he doesn't need it. Besides the solid he would want to use in this motor isn't an off the shelf grind and would be a custom piece. Most cam companies smallest solid is too big for a street/strip 396/402 Chevelle. The single plane will only kill his ET potential.

The first cam mentioned ( the Crane ) is solid. and I would highly recommend a solid grind, and that one in particular. They just rev better and make can make more power. The smallest UltraDyne solid looks right too.

Ed, with 4.11s I think the smallest solid grinds ought be fine. He'll love the revs.

Gene, you know I don't believe a BB need to turn alot of RPM to ET quick. The smallest Ultradyne solid at 243/251 @ .050 will make peak power at 6400 RPM in a 396 and wants to be shifted at 7000 RPM for best ET. Yet it still won't ET any better, perhaps marginally better than the hydraulic that I recommended that is shifted at 5800 RPM.

Now if we were to have a solid cam custom ground that is 8 degrees bigger on both the intake and exhaust lobe 231/239 @ .050 and have it ground on a 108LSA you'd be talking. This grind would make power in the same powerband as the hydraulic yet it would make more of it everywere. This piece comparing apples to apples would be about 1.5 to 2 tenths quicker.

Jim, I'll be lurking around to see what you decide on. Do you have a base ET/time for your car as it is now? Nothing beats before and after results when your spending money.

I run the Weiand stealth intake with my Q-jet. the performer RPM will be fine with a Square bore carb.

I think my head work has a lot to do with being able to still pull strong at higher RPMS. Now I see why Gene like's that L88 http://www.chevelles.com/forum/smile.gif . I have yet to run my car with slicks, but I am certain the above mentioned Ultradyne cam will net me mid 12 second ETs. I'm just not bright enough (yet) to get down to Ed's 12.3 second ET with the same combo.

Whatever your goals are, I wish you well

Well, the 4.10's are coming, the TH350 and stall are staying and extra money for "good" heads is out of the question.......So, where does this leave me? I thought the 292 would be a good compromise. I guess I'm wrong. I still have to make what I have, work. So it's back to the drawing board. Thanks for everyones help, this is'nt the last you'll hear on this subject http://www.chevelles.com/forum/smile.gif

But i dont recomend it. But that cam really woke my car up. with decent stall and a other intake than my iron peanut one and a better gear im sure for low 12:s

Jim, I still say that either of those cams is too big for a street/strip 396/402. However if you must have a bigger cam and want to RPM the motor then go for the smaller of the two. Having said that a better choice would be an Ultradyne grind 288/296 hydraulic. This cam has 231I / 239E degrees @ .050 with .550/.575 lift and is ground on a 110LSA. It will have more "area under the curve" which spells power. Look at the .200 duration numbers which you will have to get from Comp. The Ultradyne piece is 143I / 151E degrees @ .200.

Again keep in mind that both the Comp and Ultradyne cam want to be shifted at 6100 RPM in this motor for best ET.

Jan 14th, 01, 7:29 AM
Obviously, I respect your opinion or I would'nt have asked for it. I guess one of my big distractions is I have yet to find a Website or info on the web for Ultradyne. I've heard of them but, no info.

It says: 396-454 street/bracket cam. Lopey idle, no power accessories. Best with 4 speed or 2800+ converter. 3.73 gears and up. 780+ carb. 2500-6800
In reality, will it still pull enough vac. for pwr. brakes?

ed,
how do you feel about the wolverine cam part #WG1056. it specs at dur@.050 .238in-248ex. gross lift.544in-.570ex. the lobe centers are listed as 109in.-119ex. the catalog states" fair idle,2200-5400 rpm, mild bracket. advertised dur. is 300-310. it is also a solid cam with .26 lash on intake and exhaust. how do you feel that this would perform in a 396 or a 454 prepared similar to your setup? the wolverine tech told me it was too small for a 454 and would run out of steam at 5500. I stated that I wanted to shift a 6000 and redline no higher that 6300. he recommended their part #WG1065 which specs@ 248-258@.050. .570-.595 lift. lobe centers are 105in. and 115 ex. rpm range is 3200-6500. I thought this was way too big for a street 396 or 454. as you know I already purchased the X-treme energy 274 but have not driven the car yet. how do you feel this would perform compared to the wolverine solid? the reason for so much thought about this is a buddy is assembling a 454 similar to mine and we are considering this cam. btw the cam and lifter price is $113 from competition products. thanx for any input.

Jim, in my 454 it pulled 13" at idle. 9 - 10" in gear. With a 396 it may be less. If you ask them they will tell you no.

PS. these guys like to recommend big cams.

racer1320
Jan 14th, 01, 10:25 AM
rat, the .050 duration numbers aren't bad except that I'd like to see only 6-8 degrees bigger on the exhaust side. The real problem with this piece is that it's ground on a 114LSA. This piece as most of the Wolverine grinds is far milder than some of the more agressive grinds available. As I said before it's too big for a 396/402 unless you have to RPM the motor. However it won't run out of breath in a 454.

Keep in mind that with a real street/strip car compromises have got to be made. For most a reasonable idle under 1000 RPM in gear is important as well as the ability to make vacuum for our brakes/accesories without the use of a can or pump. Ideally my motor wants a solid cam that is 248/254 @ .050, 10 degrees larger @ .050 than my current stick. However it would want to be shifted at 6500 RPM for best ET, have poorer idle quality and make less vaccum for my brakes. In addition I would have to have it ground on a 106LSA to make up for the lost bottom end torque further comtributing to a lopier idle and for how much of an ET reduction, maybe a couple of hundreds to half a tenth. I prefer to install a smaller cam that allows me a cleaner idle, crisper throttle response and vacuum for my brakes. In addition the beauty of the smaller cam as with all solids is that you can run the lash tighter and have the motor "see" a larger cam without the streetability problems associated with the larger cam. I do run my cam's lash .010 tighter than spec so that the motor "sees" a cam that is 242/246 @ .050 which yielded a .06 reduction in ET, clearly indicating the need for a bigger stick. This is a far better way to go than loosening up the lash on a cam that is already to big.

I believe you'll like the Xtreme 274 better. But if it's a solid you want we can have a custom piece ground that will out perform this as well without giving up streetability.
