hello out there , nice cars on this site. im glad i found somewhere to get a little help. im restoring my 1988 monte carlo luxury sport. it came stock with a 4.3 l v6 , but i want to put a 69 sbc 350 4 bolt main in it. i have the motor rebuilt on an engine stand, pics soon to come. im running into issues on whether to keep my stock th2004r transmission or but the th350. i think i would have to have the transmission built up some , but sum people tell me i could use the transmission stock if i dont beat on it?? im not running track or using boost, i just want a daily driver with balls! if anyone could offer thier opinion id appreciate it
