340 - This thing should run better

Thanks. I'll check the timing. The 3,000 converter and headers will have to wait for a bit.

I am afraid the biggest problem might be the compression. They have 4 eyebrows (I assume eyebrows are valve reliefs?) The kit (through Mabbco) advertised the pistons as 10.2:1 for 68-71 340s. Since mine was a 72 block I called the manufacturer of the pistons to get a little more information. They said my heads have about a 65cc combustion chamber and that the pistons should provide approximately 9.4:1 compression. How can I check this figure now that the engine is already installed?

Sounds like I might have gotten screwed.

I assume a set of Edelbrock heads would be the cure all?
