'96 SS Camaro. Basically set up for NMCA Pro Stock type heads up 10.5 tire racing or
DR classes. The car fits several classes actually. We'll be running the Milan Heads up series
in All Motor class. It's pro tree heads up 16 car field. The heavy hitters in the class are
consistently in the 8.50-8.70 range. I should be right in the middle of the pack with the
ability to go a round or two at each event. I'm hoping that consistency gets me a top 10
points finish with a 9.0 package.

Pretty good power. What cam spec's, intake, carb, compression, valve train and flow figure's?

Sorry for the delayed response.
Cam is solid roller .800, 7/4 swap, 112 lsa.
Intake is a Super Victor prepared by Lukavich Racing Engines.
Pro Systems Dominator.
14.5-1 comp after machining for valve clearance.
Crower Hipo lifters, Jesel shaft rockers, Trend 3/8" pushrods.
No flow #'s on the heads, nothing special really, nice back cut on the valves.
By the way, the carb was spot on. It did respond to a power valve plug and square jetting,
but one jet size either way lost 15-20 h.p.
It likes 38 degrees timing.

Thanks for the pic's. What is the duration@.050 and @.200 lift as well as exhaust lift and rocker ratio. Which Intake? Curious as hell, thanks

That is a good car for that type of racing. What is it going to have to weigh for the class? Are the lifters and cam oversized? I hear bigger pushrods make for a gain in power, what wall thickness are the ones you have in the motor? What rear end gear and tire is on the car now? It's going to take about 1100 H.P. to compete with those times with 3550 lbs. A good vacuum pump, like a GZ will gain some. Think Manton for pushrods.

One ran our series a couple of years ago, very fast and bit real well. He'll want to consider tying down the front end as they stand up easily. Jamie Stanton's ran 8.90 @ 152.80 with a 522 making 1035 H.P.

How do you get the distributor in one of those, through the dash? :confused:

I would also think that the valve covers and trans dipstick would also present a challenge. Can't wait to see a pic of it!

Minimum weight 3350.
Standard lifter and cam dia's. .080" wall Trend pushrods. The big pushrods aren't worth much
at this rpm level other than clearance issues.
4.56 gear now w/ 29" tire. It may want 4.10's, who knows.
I have a Moroso 4 vane pump setup pulling to 16 inches.

Belt doesn't really make much more power and adds lots of $$$.

There is a lot of distributor clearance at the firewall. The issue is the carb to cowl area as
you stated. The center 10" of the cowl will have to be removed basically to the glass.
Obviously, the stock SS hood is history and I have a VFN 6" cowl hood for it.
Limiters are already on the car.
I'll post up pics once the install is complete.

There's an active thread titled something like "Wild Street Video", maybe it was in the bench racing forum, that has a champagne colored, very late model Camaro running into the high 7's. No idea what's under the hood, probably a ton of nitrous. The clip has several races from Vegas, mostly 8 second cars. Well worth the time that it takes to load.

Smart man using shaft mount rockers, easily cuts the frequency of lash adjustments in half. In that particular body, it's gonna be a bitch everytime you have to pop the hood, short of checking oil and water. I know, had a '96 Z28, working on it with the LT-1 sucked, I can't imagine having to get a BigBlock valve cover off, much less hanging over the fender to set lash, especially if you had to wrestle with a stud girdle every time.

your car looks VERY simular to GM's ZL1 Promo car.

That engine sounds badass, should be a blast.

I have a Moroso 4 vane pump setup pulling to 16 inches. My guess is that your going to have to twist the snot out of this motor if your going to have a chance of going many rounds. Your about 200 lbs. heavier than a S/S Hemi Barracuda and need the same performance. The best Hemi cars have about 940 H.P. and their record is mid 8.50s. Average runs are 8.80s to 9.0s. They have very steep gears and are turned over 9000 RPM. The thicker pushrods are worth 15-20 H.P. from what i've heard. The vacuum pump you have is O.K. i think, you might want to limit it to 12" or so. The oversized 55 mm cams smooth out the more radical camshafts some. Real good springs can give some dependability. I'd leave the gear 'till you see how this motor pulls. After a trip to the strip you'll know how far you have to go to be competitive.

Its an '02 with a 360ci SB2 powerplant and a 98mm turbo.

Its an '02 with a 360ci SB2 powerplant and a 98mm turbo. Yes Henry, The SB-2 adapts well to drag racing and more cubic inches. Sounded like a turbo deal when he said high sevens. A Kansas racer's dad had a 434" SB-2 that had a Nascar take off top end and it ran 9.12 @ 149, with no juice, at 3380 lbs. a couple of years ago in a '57 Chevy black widow clone car. He has since wrecked the car, but it had very impressive power for a moderate sized engine.

I think i saw that car or one like it at ozark. I thought this one had a 428 but it was bad. It might have been at Ozark a time or two. His name is Rodney Williams and his son is Stan Williams of somewhere northeast of Wichita (Marion i think). The car had a five speed and D/R tires when it ran at Tulsa. I heard it later went high eights with real slicks and was totaled in a rollover wreck at a later race. This motor dynoed at around 950 H.P. according to locals who were familiar with the Williams'.

Believe me when I tell you that I'm under no delusion that I'll be a hitter in this class.
I'll just be a mid pack guy who can go a round or two with some luck.
I will not run this combo on the edge. It is what it is. Spinning it harder will NOT win me
any more rounds. By the 2nd round I'll be seeing cars that go well into the 8's.
I CAN'T compete with that.
Some of the smallblock cars in the class are making 1200 h.p.
I'll be praying for people to break or blow the tires off more than anything else.
This cam and valvetrain package is a 150-200 pass package from Lukavich Racing.
They've built quite a few of these with these parts, it's a proven package.
I guess we'll see where we end up in the spring.

I've watched some videos from this series and about 40% can run low nines, you'll probably be competitive with most of the cars with the power you have. The top running Mustang (Darren Magg?) is real fast and a couple more cars ran 8.70s & 8.80s. Most were 9.15-20 and quite a few were low ten second rigs, so your not going to be too outclassed. Some of the tweeks that give you more power also help dependability too, like the pushrods and real good valve springs. Check into the PAC 13000 series springs at some point. We used less expensive springs this year and a couple of inners broke recently and our car started popping. Getting more power is a matter of upgrading things a little at a time usually. After a half season of tweeking you may have that 914 H.P. up to around 950 H.P. Good luck and keep us up on how fast it goes. How much tire can you run? I have a few more tips, if your interested you can PM me.

I believe I should be able to make some second round passes in this class.
Anything beyond that will be icing on the cake.
The field does range from the mid 8's to the low 10's typically.
Mag has gone 8.36. I think Howdy went 8.42 last year.
Kevin Patterson won the points running high 8.60's.
I have Manley Nextek springs. I thought about using 7/16" pushrods but my builder didn't
see much benefit over .080" wall 3/8" 1 pc Trends.
Shoot me a p.m. Harold, I'd like to hear about your season.
