About 3 months ago i put a used 97 lt1 aoutmatic transmission, lt1 engine & wiring harness, and front axle assembly swapped into my 97 camaro. I had a v6 in it before but my brother blew up the engine. Im having some problems. When i step on the gas hard, the engine overrevs and back fires. IS this a tunning problem or a transmission problem? Also, Would it be worth it to get a new rear end because only one of my tires peels out and i want both of them to peel out. Last, whenever i go over a bump, i hear & feel something knocking around towards the rear end on the right side which didnt occur before i did the swap. Please help me, my knowledge is very limited.
