barnym17 Depending on head flow cam etc. you could end up between 375 and 800 hp it just all depends on choices made.The important ? first is what do you intend to use the truck for? strip only? street/strip, cruiser daily driver? this question must be answered then we can proceed from there.

airboat Sorry, Lousy mood!

56chev100 well i think itl be more than that just cause it started off life as a 390hp engine and im boring it .06 over and stroking .35 in over stock and getting alumin big valve and runner heads i think im just hoping that droping that much money in it will get me mid 600's hp wise and its goin in a street/strip 1956 f100. even though im only 17 please dont underestimate me guys.

build

Do not buy those heads. they are the China casting heads that they re-work..

Spend a few hundred more and get a set of Edelbrocks,,,, you will thank me for it later.


Hp guess is just that, a guess. You can run the numbers on desk top dyno and get 575 hp...then strap that engine on a real calibrated dyno and pull 425 hp...

There are just way to many things that dictate what hp the engine is going to actually make.

I ahve a program that if you tell it the truth will get you with-in 3% of a calibrated dyno for HP,but i need way more info then you gave to even start entering numbers.

At 17 years old my question would be, how much HP do you need, and what do you need it for???

actually those heads are 1600 for a pair . Thats very reasonable for a bbc.
10-21-2009 12:03 PM
BBCMudbogger Will everything clear with a 4.375 stroke? Is there an off the shelf piston for that combo? Might find that 4.375" stroke pistons start out at about 4.5" bore.
