96 351w engine build
Alright guys i finally got a 96 351w to swap out my 96 302. I originally planned to fix the leaks throw some headers on it and call it that. Well i ended up tearing it apart and the previous owner must not have know how to change oil... Anyways i am rebuilding this motor and of course i want more power. I would really like to get 400 torque. I'm thinking a .30 over bottom end and maybe some cheap heads? I've found some gt40x heads on cl for $850 ready to bolt on with roller rockers and dual springs, originally off a 351 crate motor. My question is, can a make 400 torque with these heads, cam, and long tubes?
I'm doing this rebuild on as much of a budget as i can. Suggestions would be great! Thanks guys

IMO if you can't get 400tq out of a 5.8 you seriously messed something up, all it takes is 9-9.5:1 static CR and longtube headers. The heads/cam combo will determine where peak TQ occurs, with an RV grind you'll see the big numbers at lower rpms and with a HP grind it'll happen at higher rpms. GT40x heads are good pieces BTW.. no problem getting 350+hp and 400+ tq with those.

850.00 sounds like alot for those heads.I just sold my Edelbrock performer rpm heads for 700 with only 5000 miles on them.Unless you're in a hurry to get this engine together,I would look at aftermarket aluminum or offer much less for those heads.

the thing is theses heads are ready to go on. most other aluminum heads i've seen around my area are in the 1200 range without roller rockers or even valve springs in some cases.

well the Gt40X heads i was looking at are gone 
but now i'm looking into a possible 393 stroker kit. Is it possible to get my 400tq number out of a 393w stroker, cam, and long tubes? everything else stock maybe other than injectors?

would you suggest leaving the cam alone and going with 1.7 roller rockers? or doing a cam swap. I mean everything is apart i assumed i'm be doing a cam swap while i'm there
