340 compression ratio

First of all, Thank you all for help and information!

Rick - I need to get a compression tester and a vacuum gauge, whats a good brand and where should i get them? Once i get them ill try that out. Thanks Rick!

BluNblu - Ill get some pictures on here soon, thats a nice car collection you got going, thanks for the info!

Mark - that would be great if you could get some more information on his process and where is a good place to get a cubic centimeters graduated cylinder. do i want cubic centimeters (cc) or cubic inches? Thanks for you help!

Rocky - I will double check that vin number. I looked really hard for any and all numbers and letters on the block, but i will double check under the front left under the cylinder head bolts. I will check the balancer to see if it says cast crank only, (what other types are there and what is the best?) Where is a good place to get a inspection camera and what is a good brand, ive been wanting to get one...then i can check the top of the pistons for numbers. i could also look at the shape of the piston like BluNblue was saying. (domed, flat, ect.) Thanks for looking up that camshaft info.

Thanks again for all your help! I have been working so much. i haven't had much time to work in my shop, i need to get in my shop and get going on this soon...maybe i can get some of theses tools ordered at least.

Thanks Again!
