i vorteched my 302 and added mass air intake throttle body and did a few other mods, and i run mid 11's, be careful with what supercharger u go with from vortech , i would honestly check in with procharger, those do not take as much maintance, BUT IF IT WAS ME IN UR POSITION GO WITH A 351W or a 347 instead of the supercharger

The gt-40x crate engine that puts out 345 horse doesn't have forged pistons so supercharging would not be a good idea

you dont NEED forged internals unless your pushing over 10psi.

it would make you feel better to have em, but i wouldent say you NEED forged unless your running high boost

stroke it, that crank is shot.


Youll see where the damage is from excessive movement, and its not worth paying for repair, oversize bearing and balance.

dude, after building a 331, twice on same block, damn bearings... it cost me 2k BOTH times, first time no assembly charges, but second time i had assembly charges and a crank and other stuff, the list goes on.

heres your choices: a. buy a short block from fordstrokers.com- $1,900, i wish i went that route, and get a 347, get the 16 extra cubes.

or b. get another motor, junkyard or whatever, and turbo the bad boy, and a set of heads and and intake will be more than enough to split the stock block.

hey joel can i do a 331 stroker kit with 302 stock heads for know until i can afford aluminum heads
If the bottomend is heading sound quick, take care of the bottomend.

Then add the heads/cam/intake combination that you want later on down the road.

I think about reliability first, performance second, if you are speaking of a high mileage driver.

Maybe I am too new when it comes to mustangs, but why not just put a 351 in. Seems cheaper and stronger than a strokered 302?

City motor supply has 351w roller shortblocks for $650

Not to be the enemy of fun on the rebuild and stroke idea for $1200, but I don't think you'd be wanting to re-use your stock heads so the price would be much more.

FWIW, the Ford Racing GT-40 crate motor is a nice engine that is no slouch in performance. If you want the all new Ford motor with warranty and the extra cubit inches, you could get the Ford 342.

while yes the windsor is a stronger block but in stock stroke form a 347 will walk circles around a stock stroke windsor
