ok I have everything for my combo set and need to just work out the cam specs. Now details about the engine so you know.

Its a 400 small block bored 30 over to 406.
6inch Rods, KB Dome pistons with AFR 210cc heads, 2.08 intake and 1.80 exhaust valves.
Looking at around 11.2:1 CR
Victor JR intake with Holly 850cfm Carb

with a t56 & 3.73 final gear ratio

Look at Mechanical Roller Cam & Lifters

this kit is what appears to make the best power from what my engine dyno estimation software and compcams tech tells me. Looking to break 600hp.

Please I would just like to know what everyone thinks? As well as any suggestions you might have from personally experiences

 

I have that cam in a 396 but it's not running yet. Dart 230 head, Super Victor, 11.5:1 compression, long tubes. Not sure if it will make 600+ but it should be damn close.

Problem is you haven't told us if it's a race car or street car, double duty? etc.

WHATEVER it is for. A T-56 car like that needs more gear to go through the traps at a good RPM on 26" tall tires.. Even steeper gears if you are doing a 28" tall tire. 4:10 or 4:30 if you end up with a more aggressive cam and more RPM. Goodluck!

 

sorry this is post whoreing a little bit just wanted to say thats a ****ing awesome setup. Not worried about breaking that t-56 with 600 hp?

 

thanks for the props. yea I'm sure it'll be fun. It'll be a double duty. More of a street car and goto the race track for fun type deal..

when I get a better rearend I'll probably be going with 410s

 

Make sure you use the right valve springs! I've run 3 of the extreme energy cams. Great street/strip cams- up to 6000-6200rpm max. After that I would get valve float. I think it was because they used such fast opening and closing ramps. This was however on a hyd roller set up not solid roller, which should help you up top. I'm guessing with those heads and intake and a goal of 600hp you're going to need something that will pull to like 6800ish. Maybe look into some kind of stud girdle for valve train stability.
