and im not sure which heads to get yet
looking at AFR's 185
dont know where to go from there though
can some1 help me there too?
i want emissions legal
but i dont know whether to get 58 or 61cc or what
heres the link im looking at for heads
AFR 185's
i think i want long tube headers
theyre better right?

 

BBK Long tubes....

 

ok
now there are different sizes
what size should i get?
i think it said there was 5/8 and 3/4?

 

since you will be going turbo very soon, get biggest size you can

 

For FI get the 1 3/4"

It will REALLY help with the nitrous also.

 

going to hold off on the turbo for a bit
going to save my money for a dart block after i finish getting the heads n junk for this current 302

how far can you stroke a 302 dart block?
i hear they can go into the 400's?

 

waist of money!!!! the block you have will be fine for up to 650hp they say, for gods sakes just get the turbo son but i wouldnt stroke a 302 past 331, just not enough meat on the pistons with a 347

 

thought i heard the 302's shouldnt really be pushed farther then 500
cuz at 550 theyll crack

Ford:BBK 1979-93 5.0L Mustang, 1 3/4 in. full length, chrome headers
for like 300 bux
those the RIGHT ones?
if so ill order em either tonight or tomorrow

 

Get the ceramic. It will do you more benefit.

 

Everything I have read in the past few years says 550 HP on a stock block is about it. For street use and a 100K miler I might go 331, but if a track only car, that will see a freshening every 2 or 3 years, no problem with the 347. Yes, you can bore the Dart block .125 over x 3.400 inch sroke would give you 364 Cubic inches. You may be thinking about a 351 block. It can go up to 428 inches with a 4.125 bore.
One trick you can use on a stock block is to have it cryogenically frozen before the machining process. It strenghtens the block to handle a greater amount of power. See http://www.onecryo.com I used this process on my old 306 and ran over 700 HP through the block for about 3 racing seasons. The process costs about $1.25 per pound, so much cheaper than a Dart block, but you would have to convert to 4 bolt mains, which can also be done.
