Re: Diamond Block Questions
I would say you can tell by the fuel pump cam lobe and the maximum lift.The lobe if you have it is a dead give away.I have a B cam that appears to be unground yet only has a max lift of .270,yet all I can find on B cams puts the max at over .300..

Re: Diamond Block Questions
I looked at mine and it has the b cam with .315 of lift. It measured .895 and 1.210 I did that quick with a dial caliper so may not be accurate. It has hardened exhaust seats and I tried to do some rubbings of the casting marks and I think I see F1210 or FA210
looking at the picture. under flash it looks more like FA210. The F is the lightest letter and may just be a interesting rust formation. |
