The heads for my 422 are FINALLY done. They'll be flow benched tomorrow or wednesday. I'll be out of town this weekend so I won't be able to start installation til next week. Here's what the 422 consists of:
Stage III 6.0 heads(2.10 int 1.6 exh)
Complete Lunati rotating assembly(4.125" Crank 6.125" Rods)
6.0 Iron block bored .030"
Comp 246/246 595 or 600 lift on 112LS
Yella Terra 1.7 rockers
Comp push rods & "R" lifters
Match ported intake
Ported throttle body
42# Bosch injectors
And several other boltons

Anyone care to guess what it'll dyno? If all goes smoothly, I should be at the dyno next weekend!!!

you need a bigger cam....hell my 370 cam is just as big as your's as far as lift, just smaller duration

Yelo

450ish RWHP.......just a guess

Slowverado

i'd say 450ish aswell....maybe less depending on driveline loss

Slowverado-You're the first to say that my cam choice is too small. What cam do you have?

Slowverado

it's a raging motorsports 230/230 .595/.595 110, your's isn't to small....just prolly could do with a bit more lift since it's such a big motor

I'll see how it goes with this one. If we see like there's a lot of potential during the dyno tune, I'll step it up some.

Slowverado

thatta boy....with that big duration it should be pretty powerful though...good thing you went with the s3 6.0 heads, they will really pay off in the end with that cam. who did your heads?

RED2K

man dont listen to him. I dont want too big of a cam when that motor goes in my truck

They were done by Nasty Performance. He's been great to deal with and would highly recommend him. I've been to his shop and seen a bit of what he's done. His WS6 is pretty damn impressive. No regrets with going with his porting. So hows your build coming along?
