Quote: None this answer my questions. Its going off in a totally different direction. My 383 is all ready, that's the block I'm building. I'm either going to put it back stock stroke or 440 stroke. Who out there has a 431-438?
I have a 383 in my car. Very mild with stage IV heads and it really works well and im suprised at how much torque this thing makes. Starts and runs and has no attitude. This little motor has broken lots of drivetrain parts behind it and after 5 years of running constant 7500+rpm shifts , it remains in good condition with very minimal maintenance. Its not trying to push off the main caps , doesn't need a girdle and still runs hard. Has run best of 9.86 at 135.60 in a 3100 lb car through mufflers.
