I have a 91 caprice witht he stock 305. I am replacing it with a 95 LT 1 with a super charger...ok i know i have to change the fuel pump, rear end, and the computer setup.. my question is can i get a chip to upgrade my stock computer? or do i have to change the whole thing? and can i set my stock throtle body on the back of the charger or do i have to get an aftermarket TB? and my final question is what else? i know that there a 101 things i CAN do to get a ton of horse power but for now i just want it in the car and operational..i plan to upgrade one part at a time once the motor is in.. Please help if ya can.. I am ready to turn my grocery getter into a GT eater.
