bore to 306
 
hey guys anyone know where to get a good quality bottom end kit for my stang. i ordered my trick flow top end kit yesterday and decided f*ck it i'll do the bottom end too. cuz i might through a 75 shot on it as well and i want the motor to be solid. so where should i purchase the piston, rings etc?.. and does anyone know of a machine shop in Austin Tx or close by that does good motor work? thanks

are you going to bore it?? keep it a 302?? or wanna stroke it?? ;)

well i don't think i have enough money to stroke it. i have maybe close to a grand for parts and labor to do the bottom end, what do you think i should do? i wanna see around 350 rwhp roughly.

iff you want 350 rwhp..your gonna need a well thought out combo..but since you already order the trick flow kit....rwhp will be around 270-280 and a dyno tune may help raise that a little and the 75 shot should help you come really close to your goal... but as far as the bottom end goes..take it to a machine shop and see if it'll need a crank clean up/polish or a bore or just a hone.. they'll be able to tell you exactly what is reccommended...but you should be able to easily freshen up the bottom end for 1000 and for added strength I'd add a main cap girdle:D

since i'm just learning how everything works i decided to go with a kit. (trickflow). i got buddys that know how to do this type of work but they were bullshi^ing on exactly i needed. if i did throw a 331 stroker on there where would that put me on rwhp. whats a good kit and how much labor for the machining and the kit would i be looking at? and i would probably have to get a different cam? right?

I just had a 347 short block built by fordstrokers.com...check them out for prices= good......and you'd really need to rethink your top end combo for a stroker.. that kit is for a 3o2 and will produce 302 power.. you'll need better heads and cam and intake for a good stroker set up and rwhp can put you over 350 easy with right pick of parts;)

RE: bore to 306
 
true i would have to port everything to use this kit i'm getting so i'll just rebuild the bottom end and throw the nitrious on it. where do i look for pistons, rings, what brand, etc. thanks

just check summit out.. trw makes inexpensive forged ones.. if your budget is 1000 then you'll have to stick very basic as a decent set of forged pistons can run 450 to 600;)

well i'm pretty sure the machine work at one local shop will cost around 400. i might be wrong but i think this includes turning the crank, boring it out and blue print, and shaving down the side were the heads hit, i don't remember what thats called. so exactly what will i need for parts. i know the piston and rings kit. what about rods? is this it? sorry like i previously stated i'm still learning. i'm a hands on learner so when i do the work with my buddies i should definitely have it figured out. should i bore it .30 over or .40? thanks

RE: bore to 306
 
.030 is standard and you'll need a complete gasket kit and oil pump and cam if you decide to swap at this time..new timing chain....and once machine shop determines it needs a bore of .030...then buy pistons so they can match bore to pistons and matching rings to pistons and you can reuse your stock rods...and can have them reconditioned if desired;)
