Iv seen similar casting. GM's 3720991. Also have one in the front under passenger head of 0257665f56ge. The ending of g iv seen on the forms but the ge iv never seen anything about? What do you guys thank. Sorry but I could figure out how to post picks from my phone. This motor now has a two quad car's border 30 over mild cam. I'm trying to figure horsepower so I can put the right gears in the rear as of now they are very low.

I think you mean Carbs, not crabs, and it's bored out 30 over, not border. Scrape some gunk, oil and dirt off, the casting numbers will magically appear.. lol

Chevy Corvettes had 265 V-8 and the ones with 2-4bbl carbs had 225 horsepower. Single 4 bbl had about 205 H.P.
