I'll measure them out at some point in comparison to the Cranes I have laying around, but given work and the holidays I was hopeful that maybe someone, I.E.(You) wink had good info on them already to tie me over until I got time to look into them myself. -Trent wave



Run them. They are durable. Most I've tested are accurate. Contact Mike at B3 racing engines and have him hook you up with a geometry correction kit. That will eliminate 99.99% of any valve train issues you would be having.
