Hi Hounddog
I would be intrested in this we used to take the crank out of the 400's and put them in bored out 350's change the pistons to 327 pistons so the skirts didn't hit the throws on the crank and you had a 383 stroker. Do you have double bump heads on it? Do you know the compression? Cam specs? I am about to get started on rebuilding my car I have had sitting for to long I do have a 383 stroker for it but it is nice to have some options or a spare in case something blows up.
Now here is someone that knows the old tricks.
The 327/375 hp fuelie heads are the BEST ever double bump heads
The cam is a solid lifter cam. If my memory is right it is a 310 with specs close to the original 302.
Motor would be 10.25 compression. The 302's and 1970 LT1 were 11 to 1.
I had both motors. My 1970 LT1 Corvette I purchased new in 1970.
I ran an original 1968 Z28 302 motor in my 1957 Corvette. I sold that motor because I had to rev the hell out of it to get a good start at the light and it was a dead give away. I replaced it with a SLEEPER 400 cubic inch, the twin of this motor. The motor mentioned in this post was the back up motor. The original 400 never broke. Young people to-day don't realize how fast the old Vettes were. The 1957 Corvette only weighed 2300 lbs. We would run the 400 motor with a M22 4 speed and a 411 rear end. A solid lifter cam motor has a wonderful sound. Thompson and a few other performance tire people made street race tires. The Corvette had a strong solid frame and they would hook up well with a good street race tire. The late 60s and early 70's muscle cars didn't stand a chance when they raced one of the sleeper Vettes.
