Hey everyone! This winter I'm going to be digging into my Monte ('85ss) and swapping in some stuff from my other car that was totaled 10 years ago. I'll be putting in my motor (started as a ZZ4, and now has forged internals, will have AFR heads and a cam to match, 750 Holley DP, etc.) but had some questions about the transmission.
I have the TH350C from my '84ss (along with the driveshaft, crossmember, etc.) with a 3400 stall that worked great in that car (ran 12.3@110, and that's before the new heads/cam). I'm just wondering if I should swap that into my 85 or if I should leave the 200-4r. I know that the overdrive trans is better for cruising, but I had 3.90s and a 26" tire with the TH350C and didn't mind having no OD at all (didn't really go over 55 on any highway!) I'm shooting to have around 400hp to the tire (had 320 with the stock ZZ4 heads and baby cam) and I'm pretty sure the stock 200-4r cannot hold up to that.
Here's what I'm really asking - should I keep the 200-4r (and therefore I assume have to have it built and put a new converter in it - any ideas on cost??) or just swap in the TH350C?
Thanks in advance!
