best way to build a 5.0?

Your question is a bit vague

Do you want the most power out of a stock block?

Do you want the best heads, cam, intake?

Do you want a 'wicked' daily driver that will put holes in your wallet?

Do you want an all out drag car?

Give a bit more details on what you are wanting to know...

its hard to get 400 HP out of a SBF, it can be done, but the heads and cam required to make this power operatie WAY UP in the rpms, like around 7 -8k, by the time you get it making that power, the car will be a DOG down low and wont be any fun to drive, wont be a good daily driver either.

if you want to go the N/A route, start with a 351 block, a stroked 351 will be able to make 400 horse alot easier and more effieciently than a 302, 347 could probably do it, if you want to spend the money.

personally to get 400 horse out of a small motor efficiently and still have good street manners is a power adder IMO.

a 302 with a good HCI, and 8-10 psi with a centrifugal hits 400 pretty easy. stroke it and it really starts making power.

nitrous is also a good power adder. has more of a KICK in the ass as opposed to a centrifugal supercharger building up power as rpm increases, but the downside is your power is in the bottle and more of a hassle to mess with it. where your supercharger runs all the time and makes boost when you need it. plus if you get hardcore with the n2o, after a year or two of filling up bottle you could've bought a SC


grab a trickflow HCI kit, throw an s-trim or novi2k on it running 8-10 psi. and you have a FAST car, making 400 horse, that'll run 11s. that will drive good on the street. and could be used as a DD. if you want to make some insane power. get the stoker kit you mention, rub some low compression pistons, and bullet-proof the bottom end and start spinning the SC to the moon and make 15 psi. you will be getting with it then.

under normal driving it will act like a n/a car ( but wont be a terd, since there is the stroker bottom end with a good HCI), once you cob down on it boost takes over and you take off like a rocket.

you could also fab up a turbo setup, usually takes more tuning expierence and more money but when done right a turbo rules all.

Problem is, he was stating the question with a 5.0 block in mind.

Easiest route, keep that 5.0 engine as stock as possible, and shove a power adder in that engine bay with it.

331stroker ALL forged internals. 4blt mains aftermarket block.afr 205s custom cam some goddly big intakemanifold. and boost that beast!!! TURBO!!!!

have been looking for the same answer, hard to find, lots suggest to change stroke or go to a 351, would like to get 450 to 500 hp from my 302, my question is, the best rings to use for a supercharged 302

Still looking for answers
