Have the gasket now it'* for a 1996 chev. 454 TB same thing I guess. looking forward to cleaning the engine and trans now then install is next.

Wow, a 454'* throttle body is similar to the Series 1 L67'* TB? At least the bolt pattern and the bore... Could you please post some pictures when you have the time?

This was alot of fun went in no problems. Someone said the frame would have the threads for the upper motor mount that is right, its almost like pontiac wanted to */C the 91 or older at the time but just did not......

Update,I have installed the wiring on to the engine and put it through the firewall. The wiring is still not finished I dont have an air bag or HUD so I know this wiring is useless This will end up being the hardest part of this project. The feul lines are in a different form 91 has metal lines and 92 has plastic I will have to have them made up at the house of hose. the axles have abs differences and one is longer then the other. positive wire to the alt. is to short also no biggy.

UPDATE:Gas lines are done and installed,axles are in,fuel filter, trans filter and gasket done. Had to get a trans cooler to match this setup (done).Power steering cooler lines converted over.Have my dash completely pulled out in order to do the wiring. My best guess is that I'll have to trace every wire to it'* origin to make it work.I'am also going to gut the air box.I'am a bit cunfused with the TCC wiring the original has 5 wires and the new one has 7.??? But all and all guys so far very straight forward conversion.Attachment 1089

Well the car still sits in the garage unable to move under it'* own power . The wiring is the most time consuming for me. I have spark it will turn over (BUT) no fuel the pass-key2 fuel disable works well. I have no pass key 2 in a 1991. This is the only thing between me and starting the car now. ????? Has anyone ever wired around the pass key2 module?THX

I have a VATs procedure, but that'* 92-99, it'* in electrical in the tech info area. It might be of some help.

what ever happened to this project? which year did you end up taking the supercharger from? ever get it running?
