Low vacuum question

I dont believe 360s ever had any steel shim. The originals are composite, and were about .035" thick if I recall right. That cam grind may be a circle track grind, like for a "claimer" or stock type engine..I had a rebuilt 440 I bought that had one similar to that grind.

Ok on the head gaskets. I thought all had steel shim types but it's been yrs. since I tore apart a stock 360 and I didn't remember. So if that's the case the Fel-pro probably isn't much thicker than the stock gasket and the lifter preload may be a little tight due to the shaved heads so Sox and Martin may have been right about that. I'll have to check into that.

Thanks Moper and BJR for the cam lesson. I think I'm starting to understand how they work now. I wish I would have known a little more about them when I put this thing together but oh well. I opened it up in the alley the other day and it actually didn't run too bad. Not a terrific 60 footer but ater the 60 foot mark it came on hard. And that is with no tuning on the carb. and a old style Torker intake which I plan on changing to a better RPM air gap which should help the 60 foot. Thanks again guys.
