the good thing is i have 8 1/4 rear on the car right now i have trans that went with the 318 :rock: what i want to do before i get the engine is is to rebuild the front end and upgrade the suspension also get the trans rebuild so i don't have to worry about it. i was wondering if a trans cooler would be good idea, i also was think about putting in oil cooler too but i think that would be little over kill but if it help it is good in my book
