GMC V6 engine compression ratio

[Erl]

I am rebuilding my 305 V6 and doing several performance improvements. First I bored it .030 over. I had a the cam reground for more performance, since you can not buy a new one. I have GMC 351 V6 magnum heads, intake and exhaust which have much better flow than stock. The heads were ported and polished, by me. The heads have been milled .070 to give 8.8:1 compression ratio. I am using a Holley 500 CFM carb and a custom Buick V6 HEI. I hope to pick-up about 40 horsepower. When it is finished I will take it to a local dyno, then post the results. I am sure someone will tell me to buy a Chevy 350 to get better performance and save money. I want the look of the original engine with some more power.

Thanks Erl, I will be very interested in what your results will be. I guess I'm just a rookie with this engine. I'm fast learning that you can lug this engine more than the norm. I'm also finding out that my old truck is kinda rare so I think changing the engine would be a disgrace to its history. Keep the progress posted.
