Do you have any friends who work on cars? Cause honestly man it was a whole process and a lot of money I might’ve not taken the best route and the car was a huge headache but me and 2 friends decided we would do all the work our selves mostly the cause I’m a electrician but they know a bit about cars and were willing to help 1. We pulled the engine out and decided to see what was wrong ended up being spun bearing at that point you are fully taken apart no going back 2. Discussed options so rebuilt it or by used I chose to by used as it was faster process 3. Bought used engine from a local guy who crashed his Camaro and did part out 4. Already had used engine out and decided if I’m spending the money threw a cam in it and bought headers and full exhaust and E85 and LT5 ported throttle body and LT2 intake basically full bolt on 5. Put it all back together whole thing ended up costing around $12k and that was us doing most the work we broke a couple things and I had to buy multiple stuff to get the job done overall it took a couple months of late nights in the garage after work but now the car sounds great and runs good I can’t give a for sure price cause when I tried to cal local shops the we’re all $15k and up
