Re: Question About Sleeving A Block

I have sleeved and re-sleeved hundreds and hundred of holes. There is no reason to use a torque plate or anything else. The sleeves are not that round anyway. I never used .062 wall sleeves either, unless I had no choice. Once the sleeve is installed you want some wall thickness because you have to ...

Re: Solid roller lifters on hydraulic roller cams

I have heard of people doing this. Question is why? And what's the reliability on this? Will it last very long? I don’t use hydraulic lifters any more because they are just as noisey as a solid anyway. Plus the hydraulic lifter is a shock absorber in the system and a solid lifter takes that out. Yo...

Re: Who regrinds the lifter face crown on used lifters

I have a few used sets of older solid SB-BB Chevy lifters. Do you Guys know of anyone out there that will regrind the lifter face crown to the 35 degree face radius and add the small oiling hole to? What’s the price? And who dose it? Thanks for looking, =D> Ron I sent mine to Schneider Cams and had...

Re: Push Rod Length: Shorter vs Longer

When your calculated push rod length falls between two standard measurements, do you go longer or shorter? Say I find 7.385" is ideal. So is it 7.375 or 7.40" ? This is a hydraulic roller with .575" lift via 1.6 rockers. With a hydraulic lifter it won’t matter. Buy the one you can get and send it.

Only if you can’t buy an aftermarket rod. I you an any work an OE rod is just maximum work near zero gain.

Superflow parts

Any idea where to get the parts to rebuild my 833 absorber? I can’t find a thing on the web and the last time I called Superflow I wanted to be the last time I called Superflow.

Thanks

Re: Diamond hone oil/coolant

I have never seen a Diamond stone use anything but a water based coolant. An oil based coolant is needed for vitrified abrasives but not Diamond or CBN. Water based coolant keeps the temperature way down and makes it easier to keep the bores straight.

Re: How much to flow heads

This is a red flag for me. I'm a retired aerospace machine shop owner so, I have been in business and couldn't do the above, to anyone. The only way I can see something like that that to be ethical, would be to give a big discount on the flow bench so, the customer could actually see what that "spe...

Re: How much to flow heads

You need to cover the additional employee's salary + benefits / insurance + taxes + resources consumed (consumables, bathroom supplies, etc.) in revenue and then profit on top of that. So an employee making $60k (which isn't even all that much) will need to bring in $100k+ in revenue for it to real...

Good questions.
