Well guys, I need some opinions. I picked up my 454 Monday night and it's now at home resting on my engine stand waiting for the transplant. The engine was recently rebuilt and is moderately stock. I plan on running headers, an aluminium intake with spacer, a Quadrajet, and a high voltage HEI. Nothing too fancy, just well proven components. I had planned on running a 700r4 behind it to gain the overdrive, BUT I'm starting to think that even if I beef it up that it will not survive. I currently have a recently (13K mi) rebuilt TH350 in there as we speak. I think I'm going to wait for a TH400 before I run the 454, but my buddy has this kooked up idea of slapping the 454 in there with the TH350 just to get the project started. The truth is I know he just wants to see the big block come alive. I'm hesitant to do it because I have the paper work for the tranny (Aamco life-time warranty) and I know I can sell it and at least get some cash for it. So my question is, could the TH350 last at least until I find the TH400? I know myself and I'm going to want to run that BBC hard, so what should I expect? Thanks for the input! It's not what you buy, it's what you build!
