hi. i built and ran a turbo 350 in my 700 horse big block chevelle for 10 years.low 10 teen foot brake car. i still have it in my 71 vette and if you want i'll try to remember how i did it. i checked it out after about 120 runs and still looked very good. i did what i called some unusual things but i had some help from my machinist friend and some tool and die maker friends. they know metal and hydrolics very well. denny
