I'm not questioning you Chris, I just thought that all this was needed or the cam would make the engine a dog. Is this just the optimum set up for best ET with that particular cam when they say this?
Look at it this way,my cam says you need the same gear and convertor and I went a 12.99 with 2.56 gears (12.56 ET with bigger valves and 3.31 gears)
There is more to optimum ET then just putting in 3.73's
You won't need to shift that cam at 6500 either even though the powerband says 2500-6500..5800 shift point will probably ET best with that Lunati cam.
Case in point,my cam power band is 2000-6000 and I shift at 5200 1-2 and 5500 2-3
Here is my cam: http://www.holley.com/302A7LUN.asp

I am also the guy that put a 238/248 @ .050 cam into an 8 to 1 454 and it ran a 13.30 first time out with 3.07 gears,no tuning and a torn secondary diaphram.And the car is totally streetable with that big cam and low compression.

That is hope for guys like me with "cam envy"....interesting results. Goes against everything that one would hear. For a long duration/low compression combo like that, do you degree the cam any differently?

That's very odd...nice results though . Maybe just what Mr. Pantera needs...

We installed it straight up.
it is a stock,low buck rebuild 454 in a crate from the parts store.
It does have .030 over hypertectic flat tops and 781's
We added an Air Gap RPM intake,small tube headers and a 3310
It will be in the high 12's next time out.
Cam sounds awesome and pulls instantly.

Re: Budget Street 454 build

Please don't forget about the two cam's I suggested for GRUNT!!

That said, I think UDHarold pushes his ---

272/217, 112/?, .515"/.515" lift as the best cam for pulling trailers, car-hauler or boats. Excellent bottom end and mid-range torque. Works power accessories. 1600-5500!!

GRUNT is what you will need, what b/c of your low, "PROBABLY", like 7.9 to 8 to 1 CR is all!!

Get your engine up to like 9.5 to 1 CR. to almost 10 and install some of these bigger cams and GO!!

Then, a UDHarold designed cam will come on STRONG!!

As always, jmho!!

I have all ready proven beyond a reasonable doubt that a big cam will work with low compression and be totally streetable. If you heard this low compression 454 and went for a ride you would certianly be convinced (and it runs ALL DAY on 87 octane)
Those other cams are way too small for a 454 performance application and will NOT make power up to 5500..as I have stated,my UD cam is rated 2000-6000 and I shift it no more than 5500 max so that little UD cam you mentioned would probably fall off about 4500
Keep that cam in mind for what it designed for: towing!
If the other two cams I suggested sound too big then go with the cam that I currently run (223/231 @ .050 .525/.550 112 LSA) which got a 4000 lb big block Chevelle into the high 12's with a 2.56 gear.

Re: Budget Street 454 build

I used Chris's cam in my 9:1 454 and it was very impressive for the street. The LUN-60203 is the improved version of that cam. IMHO you would not be disappointed with either cam.

Re: Budget Street 454 build

I just built a 427 tall deck bored .060 over for a total of 440 cubic inches.

The tall deck has 4 bolt mains and steel crank.

I put a longer rod so I could run a car piston.

I used a Team G intake which is rated 2000-8000 rpms. Its a single plane,but acts like a dual plane according to several people who have run it. It also allows you run a regular distributor instead of slip collar one.

I have about 9.2 compression and decided to go with a Voodoo 60201. It is rated at 256/262 and 213/219 @.050 and .515/.530 on a 112/108. DCR came out to 7.7. I wanted to run 87 octane.

I installed it dot to dot and it was degree at only a degree off.

I used 781 heads and have a 670 Holley Street Advenger on top.

I also have a Holley 3310 I'm going to switch to.

The headers are just the cheap 90 dollar ones from Summitt.

I have just tooled around it so far.

I did get on it once and the cam is rated from 1000 to 5500. However, it feels like it signs off at around 5000 maybe even 4800.

Its in a work truck with a stock converter and a TH350 and 3.08 posi rearend.

Re: Budget Street 454 build

I'm in the planning stage of my Street Performance 454. I hear everyone rave about the Voodoo 60203. Will this cam give good street manners with power brakes and AC?
