408 guys, need info!
408 guys, need info! Hey can you guys running 408s post some dyno sheets and info about your setups for me? I'm thinking this is what I'm gonna build and wanting some input from you guys. Anything is appreciated, thanks!
Yes I've read a bunch of them. Haha. Also, I'm wondering if I would be ok running a 4.125" stroke to get a few more cubes, or if it would be better to stick with 4.000. It will get a large cam, tfs heads, fast 102, and spun to around 7000-7400 rpms depending on cam. It's not daily driven, just fun on the street and occasional strip. Any input?

I'd stick with the 4" stroke...once you go over that your looking st a lot more work and less reliability.
I don't have any dyno sheets for mine, but here is my set up=
04 6.0 iron block, 4.030" bore
Callies forged 4" crank
H beam forged rods
Flat top coated pistons with valve reliefs
Ported/ milled 241s (58cc chambers)
12.56:1 static compression
255/266 .624"/.624" 115 lsa comp cam
Comp lifters
Trickflow hardened push rods
Ported Edelbrock proflo xt intake
Fast 90mm tb
60 lb Motron injectors
Runs on 93/92 octane, full timing, no knock
I haven't had it back to the strip or on a dyno with this setup, but o can tell you that it has beat quite a few crotch rockets around here

Here is my setup
Iron 402
TFS 215cc Heads (64cc)
239/243 624/624 112+2 LSL
Yella Terra 1.7 Non Adj.
Ported Fast 92/90
1 3/4 Headers
2.5" Exhaust
With a 12.5 A/F and 27-28 degrees timing the car made 50x/46x, it would help to do some bigger exhaust but im happy for now. With the smaller heads it really has a ton of low end power and holds over 500rwhp to about 6400 before it fades.
