You can vary compression by chamber volume in the head plus how much dome or dish you run on the piston and how thick the head gasket is. You're not stuck with any pre set compression ratio with any rod length. Check around before you order parts. Mismatched parts will make any engine run like crap.

Thats a good point. I will have the help of someone with years of experience, hopefuly nothing major will be overlooked.
I have another question, now about lifters. What are the advantages of roller lifters, which type should be the most cost effective?
Also the machinist recomended I get an aluminum flywheel because I have a manual. I looked them up and 300 bucks seemed to be cheapest I could find shipped. Maybe somebody has one, and can attest to its worth.

Roller lifters allow the cam to have more agressive ramps. Basically it lets the valves open sooner, stay open longer and close later. Unless you have a factory roller block, you only have one choice in roller lifters, that would be the retro fit kits. You will also need to upgrade the springs, even with a mild roller. As for the aluminum flywheel, I'd stay away from it in a street car. What it does is reduce the weight of the rotating assembly in the engine. Which will allow it to rev more quickly. But, it also reduces the inertia of the rotating assembly. What does this do you ask? Well, when you pull away from a stop. The motor doesn't try to die when you let the clutch out. With the aluminum flywheel you will have to wind the motor up and let the clutch out and hope it doesn't die. Great for a race car, not good for a street car.

In a daily driver the aluminum flywheel and clutch will have a very short life compared to a steel. Tom is right all the way on that one. I have seen this tried many times through the years and it never works out, they all ways end up back in there putting a steel one back in the car.

Thanks for the info. I feel like I am going into this with a lot more knowledge then I had a few weeks ago. I am keeping my steel flywheel, it will also leave more money in my "budget" for better heads.
I was supposed to be pulling my engine out this week, but with Syracuse nationals in town it might have to wait a couple more days...
