It is 4" stroke with a 4.182" bore.

The only changes I made were necessary. I had to change the motor plate but, retained the newer belt drive. I also had to install my pan and dry sump pump as it all fit. The only performance change I made was my Edebrock 2816 Intake I had. I did convert it to a 4500 flange. I will need to do some welding and cosmetic work on it when I get a chance. The Intake that was on it was a very small runner Mopar intake.

I really can't wait til the winter where I can take it all apart and tighten some clearances and fix it for spray. It should really be fun then.
