Re: .875" Hyd Roller Lifter

I am looking at the non-link bar lifters. Now wonder if the Ford lifters have a .700 wheel like the early chevy

Re: .875" Hyd Roller Lifter

Ok so the question now then is does the sbf have similar oil band spacing and length as the chevy.

.875" Hyd Roller Lifter

Is there a quality commercially available hydraulic roller lifter in this diameter that has the oil bands in the right places similar to a SBC 1st gen, with a .700 wheel?

Re: Blaster Cabinet Help

Give these guys a look, my current unit. Very low maintenance, media change in 5 minutes, clean the bags and empty the dust drawer another 5 minutes. I use glass protectors and LED T8 lighting

Re: Blaster Cabinet Help

Having owned and wore out several, I think trinco, clemco, empire, ABS, are all good. I have owned a BadBoy blaster for a few years and it is decent plus me affordable. Mine does soda, poorly, or siphon.
Aluminum oxide will work well, as well as black diamond for rusty parts.

Re: Pontiac 400 heads

Now flow the head backwards and report. For anyone interested these is a ton of information here and on the web written by Larry Meaux and Larry Widmer on the "Low Lift" topic.

Re: Valve Seat Cutting Process

This can be done on a Serdi too but running a single point cutter on an older lower rpm spindle and an interrupted cut is not easy on them without pilot support. Not in the budget for me to mess with a Newen. The quantifiable gains are important too when trying to justify an ROI.

Re: Valve Seat Cutting Process

So we run a live pilot machine with a dead pilot in the guide and live in the tool holder, offset? I don't think I am in for that. Or buy a Newen, can't afford that.

Re: Valve Seat Cutting Process

Re: Audie Flow Pro

You need to be sure the port is selected properly in the program to assure the program communicates with the module. The newer ones are usb, older used rs232

Re: HD Panhead Valve Stem Height

Sometimes I use oversized valves if the seats are sunk close to limit to restore stock protrusion. On the intake it allows a better throat ratio and the SSR can be fixed to flow better. I always use the lower spring seats with reliefs to seat on the head casting not the guide boss. Kibblewhite seems...

Re: Aluminum metal pretreatment.

David, how would an intake or other die cast engine part appear after the alodine treatment assuming it was glass beaded first? Besides sealing does it change the appearance? TIA

Re: Wet Blasting engine parts

I did a demo of one of these machines at IMTS. I was not impressed. There is so much water flow it is difficult to see and I didn't get the impression this would remove stubborn carbon, but perhaps with the right media it would. I prefer the old standby, glass beads. I then clean the parts well in a...
