347stroker vs. blown 4.6

[josh0092002]

hey u guess, ive just got an 86 302 block. ive read alot about 347 storkers. i posted earlier on making 500rwhp with a 4.6 in my 96gt. an well i know either or will be expensive. so i was wondering what u guys think, i dont know which would be better a 347 or a blown 4.6, i really enjoy this site. i really enjoy all the feedback i can get . please any an all feedback would be great thanks again u all.

i love 4.6 but i would do a 347. thats why im tryin to sell my car and get a 94-95 w/ 347 w/ vortech or procharger. but the long and the short of it is its your car and its about what you want in the long run

have fun switching k-members and the wiring harness to make that 347 work.

unless you are paying 2 grand for a dart block then your wasting your money because the stock block literally breaks in half with hp over 500(a good 302 hci and supercharger). a forged(pistons and rods) 4.6l will handle 1000hp.

so the 4.6l is a better block huh??, the reason i asked is cause i got the motor out of a van, and as i was told, the 302 block was like a truck block, it was supposed to be built stronger than normal 302 blocks. i love my 4.6 but i would love to have the low end torque, from the 347, i look up an asked about a storker kit for the 4.6l and everyone says dont stroke the 4.6 to long of a stock stroke in the first place. "it is to be noted that i no nothing about engine blocks or hell even where to look up info on them"

 

[quickstang_1994]

Yes by far. All you will need is a set of rods and pistons for a killer bottom-end. All Ford 302 are the same minus the $2k dallar block and if I was spending that much Dart has the best block.

I'd bore out the 4.6, forge it up and run Big boost.

ported PI headswap kit with cams, tune and your good.

well, you'd have to then worry about your tranny, axles and suspension to get the power to the ground.
but that's all fun stuff

ok i think ill go the 4.6 route instead of the 347. so with that in mind someone tell me what big bore is, ive read a few things on here with people saying something to others saying "just go big bore" iam lost on that one, is that another/better way for hP?

check in the 4.6 forum there's some threads on the topic.

basically better power curve from a bore, but it is more expensive.

Stroker is also good, don't believe the hype about the length.

or you can just forge it up good OL 281.
Remember the "terminators" are 281 cubic inches.
