ok im looking to buy a cheap v-8 i have a questions if i buy a 289 will the heads be the same for a 302 and other items too the reason im asking is cause i want to build a hi profromance fi twin turboed engine ( i no it is gonna cost me but imm will ing to do it i love my car and im gonna make it how i want to plus why build something whren it wont be wat u whant when ur done) i no there a thousands of items for the 302s and some one once told me that the 302 is just a bored out 289 and they are widely used as replacements for the 289 ( and form what ive seen a bit cheaper ( yes i know with a turbo it wont be totaly cheap but im gonna go cheapest way psoible after all i am 18 and have other things people say are more important than makin my car the craziest daily driver in cumberland county nj (College lol jm it is important ) so most of it might be form a yard but can you interchange 289 parts and 302 parts is the utimate question if anyone has sugestion im open to them thanks (if i can find a 351 cheap enough i might go with them too so just give me some ideas thanks ) if anything sounds upsurd im am heavly medicated so please just dont kill me ( i had surgery on thursday on my knee)

 

the 302 is a 289 with a longer stroke


either is a fine engine, but the 302 is about 100 times easier to find

 

You will need low compression pistons and forged everything... unless you plan on running next to no boost. Honestly, I love twin turbo setups, and I would love to do that to my Stang, but being 19 I know I have no where near the funds to do it right. A big cube motor is waaaaay cheaper and less maintinance.

 

As said the 302 is a 289 with a longer stroke.But they dont make the 289 anymore so keep that in mind,hence 302 parts are easier and cheaper to come by,however once again they are practically the same motor,so a lot of parts are interchangeable

 

yeah but if i find heads for a 302 will i ber able to put them on a 289 block

 

Yes you will be able to put them on a 289. Not sure what your situation is, but try looking for some gt40 heads instead of the 302's.

 

+1. Stock heads wont flow near enough for any kinda performance setup, muchless twin turbo.

 

i wasnt gonna use stock heads i was saying if they only say 302 and nothing bout 289 i was looking at the gt40 heads

 

one more thing what items sould i invest in to ensure reliabilty with the turbo setup and what is the specs of the gt40 heads i have read alot abot them but i cant seem to find the specs now thanks guys

 

turbo motor reliability = exhaust valves made to work with high heat / turbo applications. forged dished or flattop pistons, ummm.... thats about it.
