Ok billlsbird, I might have something for you, since you are limited by your compression and dont want to tear down the whole engine to change the rotating mass I have an idea for you. Since you are already putting on a blower no matter what it seems there may be a way for you to lower your compression without changing over expensive parts. The new Cometic gaskets can be had at up to .125 inch compressed thickness, this I believe is the maximum thickness made. The smallest that is made by this company is the .039 compressed gasket. If you have a similar small gasket, which I believe you do you can take off your heads and add this gasket to effectively lower your compression ratio without causing head gasket issues. NOW I have read that this has been done to a big block that puts out 950 hp and there are no issues with the gaskets. You, of course dont have to jump to the biggest one but its an idea. However, here is the rest of the story, the mating surface between the head and the block must be VERY true, so you may or may not have to disassemble the block to make sure that it is good enough for these gaskets...which should be done with a blower motor anyhow.. Next, you would likely require longer pushrods to compensate for the extra thickness, and keep in mind that the quench may not be so great either, BUT since you have aluminum heads and a blower, lower psi, maybe the fuel injection and pro injection would completely keep you from this. The gaskets are like steel shims that sandwich a billet piece and I have heard good to great results with them so far. Just an option you may want to look into. www.cometic.com is where you can get more info on them. You can choose to use em or not to, either way you will make some nice power going blown. Good luck!
1st. Gen, Thank You ... I went on their web site & I'll call them tomorrow. That could be the perfect solution to my compression situation. I need to pull at least one head anyway as I have a striped out spark plug hole & I believe tapping it out from the inside is the only way to go. And yes, you are correct, my gasgets are not thick ones...... Bill....
