I would but my connection is SLOW. It barely loads this page.
Anyway, off the block is GM 3970010. Years? 2 or 4 bolt or anything else you can tell me.
Heads say SN 30055 and the other SN 30061. TFS TW? G1? G2??
Thanks

010 casting blocks are good high nickle content blocks and are worth keeping. Whenever I go looking for a 4" bore block to build a 350 I'll only grab 010 castings.

Best MPH on a time slip: 117.87 altitude corrected to 126.10
Altitude corrected rear wheel HP based on power to weight ratio: 476.5

Racing at 3500 feet elevation but most race days it's over 5000 feet density altitude!
