I got a 1995 383 stroker engine in my car. Heads were never ported and polished so im runnen stok lt-4 heads with a 224 cam. The decision im having problems deciding is go with sts rear mount turbo or go with heads ported and polishes with bigger cam. My cars is maken 350 to the wheels now will i see 100 horse out of the turbo and is anyone running the system?
