Thankyou for your feedback and info... i hit the wrong button on my laptop. lol I found out about the block and it is a 202. now on to the fun stuff.... to bore it out. :) Discovered that is is a highly sought after engine, my guess would be due to harmonic balance that is actually internal. I removed heads today. need to do some more cleaning on it to get more numbers off of it. I guess my 64 Chevy pu truck is gona be a lil faster than I thought. ;) Thankyou for all your help and information.
