11-12 is usually considered minimum. I think I am making 7-9HG and my power brakes worked but were not the easiest as the pedal was kind of hard at times.

Thanks Flash. It's what sold me. I'll update my profile and get some pics posted. Thanks again!

This. I tend to not like a cam with less than 15-16 inch/hg for a driver/cruiser. (I'm getting old)

I have not yet had the chance to test vacuum yet but I did have a question. While working on the rear end this weekend I noticed the fuel lines coming out of the gas tank, the rubber sections look like they need replacement. I believe one of those lines is a vacuum line is that correct?

I think one line is just a return line ,no vacuum I think .

I'll have to look into it. It seems as though there were at least 3 lines coming out of the tank

Finally got a chance to measure the vacuum. I have about 6-7 HG at idle. I'll need to look into an electric vacuum pump or the hydropump. I am sure there is much opionions about what is best and what people like. the Hydropump seems to solve the problem and not look bad either. Any feedback would be appreciated.

When you say hydro pump, do you mean a hydro boost set up? Like what Turbo Buick Regals had? And what the late model Ford Mustangs employ? It relies on the PS pump and fluid, no vacuum involved. 6-7 is horrible, must be a really lumpy cam with a lot of overlap.

I purchased the car with the rebuilt engine but I did get the cam specs and talk to Comp Cam. intake lift is .508 and exhaust is .511- And yes I did mean hydro boost. Reading other fourms/threads, I hear of it often being used successively albeit has cost associated with it

Lift wouldn't be the deciding factor. What are the specs for ICL, LSA, and the duration at .004" & .050"? Those are the numbers that are used to determine the manners of a camshaft.
