[Svo 377w]

Hey guys building a 377w svo 9.5 block bought a shortblock dont know much about it has build sheet but not alot written on it has eagle rods and a ford racing crank. Has venolia inverted dome pistons. Was wondering what size combustion chamber would be the best for boosted application. Want to go with the AFR 205 heads dont know whether the 58cc or 72cc

Without knowing the dish volume you will never know the actual compression ratio. So it's one big guess right now

Do you know how to measure dish volume?? What tool

Flat piece of plexi with a tiny hole. 2 dollar graduated burret and do as the picture shows except with the piston. Problem is if the piston is below the deck at tdc it wont work since the plexi needs to lie flat on the piston.

Piston sits flush with block at tdc

What is the piece of plexi with the hole for?
