A friend of mine is buying my 95 Formula roller and will probably be putting in a carbed traditional SB. He has the motor and will be using it as a drive it to the track weekend kinda ride. I would like to know if anyone here has done it and what were they able to still use? Can he run a 700r4 and use an electronic speedo sensor? Is there a wire that the pcm uses for tach signal to make the factory tach work? Will the fans operate normally with the lt1 sensor and the pcm not seeing the engine running? other questions to follow im sure. Just please dont lecture on how the lt1 would be a better way to go. Thanks in advance,you guys have been a big help on alot of things with that car for me and will be for the 97 I picked up to replace it.
