NEVER THOUGHT ABOUT kEVIN OR STU
I WILL GIVE THEM A CALL MONDAY

Hi guys I have a KW FN bar thats been sitting in the corner for years as the air center head was crashed 1 to many times byt I want to put it back into service. I talked to the KW guy and hes asking $4000 for the parts. I called a couple years ago and was quoted about half that cost to do the same a...

The carb base is flat. The manifold flange is flat except for that eroded area on the left side. I'm going to try the $10 solution first (RTV). If that doesn't work, then off to the machine shop. Thanks for the suggestions. Here's something to consider RTV silicone in not for use with gasoline. I d...

Hi Archie
You may consider a midget hone head if its fora sunnen machine,
I hane a std and a midget and they cover everything I do

The 2bbl will give you more low end and the Rochester carb does work well for this application. Putting a 4bbl intake on it will kill what GM already designed well. Making the throttle bores in the intake slightly larger and putting a balance port between the divider wall much like an H pipe in the ...

I recently picked up their double adjustable pushrod length checker. It looked like a nice piece with a super wide adjustment range. Turns out it was .040 off. I set the length to match a pushrod with a 12” caliper. So checker and pushrod both measure the same oal. Actual pushrod had .040 more prel...

Noisy is the complaints I hear. I see HD heads from time to time and the valve train parts on some new replacement heads just seem to float around over the guides also causing noise.

But I am told by the local HD guys the GM lifter is much better then the HD lifter.

Personally I would go with the 781 castings. They take all the std valve train parts and there is less chance of pulling a thread insert if using stud rockers and the extra costs that go with non common parts. Guys worry about the exh guides leaking but theres a fix for that. Pull them and ream to ....

PM me the details regarding condition etc
A pic would be good as well

Some use a roller hyd. lifter and I have been told that there is some GM factory roller lifters that sub in place of the HD lifters. I would contact Johnson lifters ( not Hy-lift Johnson ) as they produce a high end roller lifter and I am told that have restarted production on FT stuff for solid lif...

The modern Rover engine uses a straight sleeve in an alloy block. While they come loose over time the fix is a flanged sleeve so they stay put for ever. The original blocks used a chemical retainer of some kind but they were prone to cracking behind the sleeve as well but its funny when they start t...

Liberty heads look just like all the other china heads. There's a ton of them out there you can use, I would get them bare and add my own parts and get a good valve job done. X2 There is lots of those off shore heads out there but again get them bare and add some better quality parts. There is real...

Hey guys looking for a set of decent light weight I beam or H beam rods for 2.100" LJ GM crank 927 pin. Must have 7/16 cap screw style Bolts. Nothing thats burnt up bearings and sprung the caps. This is for a claimer style engine so cost is kind of a concern but just did not want to go the ebay...

Without the rocker ratio, no one can make an intelligent recommendation. [/quote] 1.5 ratio on intake and exhaust. Mike, also would you take a stab at what a safe valve lash would be? Thanks [/quote] Since there's no way to know how aggressive the lobe profiles are, I would go with the ISKY 9935 spr...

What cam core size do you plan to run??
A customer had issues with a world block and cam flex and would loose a couple bearings from time to time.
Went to 60mm cam core and issue was solved.
Not a Hemi block but the RB style block.
