We run a 440 w/Eddy rpm heads and the Eddy 2x4 intake. Box stock 600 Eddy carbs, 10.0-1, Mopar 557 solid, headers, 4.10. In an all stock 65 Belevedere II. It's been a best of 11.28@116. Doug

I had one recently with a crack wall next to the throttle valve. It had no kickdown, and early shifts. The easiest way to test? Install a pressure gauge in the accumulator port. Disconnnect the kickdown and manually move the lever full rearward. There should be 90-100psi. If its low it's time to...

Close to 100 psi Lifter bores are a huge internal leak, especailly when worn. Doug

Now this is an area that can be tailored. Though not necesary. There is nothing the matter with 70 psi. The power loss is miniscule. How ever by using a lower pressure relief spring, adjustable relief spring plug, or trimming the length of the relief spring will lower the upper rpm pressure...

Thats only below 11.49. When required those extra bolts do not go into the block. They go into a mid plate between the block and bell housing. Doug

If you think getting the pan off is a pain? Better rethink trying to fix it in the car. In the last week my pan has been off, cam was damaged, new cam checked for spec and degreed, valve springs pressure checked, checked for coil bind, (required master cylinder removal, built a new windage...

I would like to know how the water jacket issue was repaired? Being these heads are nearly 60 years old my bet is the water jacket dimensions vary. Not to mention the corosion aspect. Doug

318 Magnum heads, 360 Magnum short block, long headers, smallest duration roller cam, T-quad. Doug

Run a HV pump w 5w/25 0il. To be honest the groove won't affect pressure. The grooves are larger than the bearing clearance itself. That's what controls the leak. Doug

In this instance the thrust was the concern. As you can see the trust surfaces are heavily relieved. Personally I like the 3/4 groove as well. Cleite has done testing for those style grooves. According to Clevite they performed better than other styles. I'm sure Clevite/Mahle knows more about...

I personally have never seen a worn cluster gear. The shaft. Bearing kit and blocker rings are pretty cheap. I can do them. How far are you from Detroit? Doug

Slightly more like 3/4. Doug

Oil pressure is very simple. It's flow volume minus internal leaks minus viscosity. At idle the volume can not be increased by a stiffer spring or shimming the spring unless the by pass is open at idle. Which is not the case at 20psi. The internal leaks can't be changed at this point w/o engine...

The counter shaft is loaded in 1st, 2nd ,3rd but not 4th. It also spins in neutral with the clutch released. My bet is it has worn counter shaft needle bearings and possibly the shaft or counter gear. Doug

The Inland shifters were problematic even new. Hurst will be a much better option if you are nit worried about originality. Doug

No need to file slots on the Clevite MS2233HG . They are notched already. Doug

I'm about to degree with the head on. #1 Mount the dial indicator pointer on the edge of the retainer where it clears the rocker. The 2nd valve backon the head being the intake valve. #2 Mount the degree wheel with a pointer at TDC when the crank is at TDC compression stroke on the #1 cylinder...

First of all nobody checks for anti-freeze. I always run some. The cut on the surface looks pretty rough. Looks like it was done with a Storm Vulcan cutter. I'd clean the pits real well. Scrape some JB weld into the pits with a razor blade so it's flat. (dont laugh it works at 15-1 comp). Then a...

My race motor uses unmodified Clevite 2233HG mains. Race converter that is always loaded hard at the starting line. 5 w 25 oil. Never had a thrust issue in 11 years over 1000 passes. Motor makes around 900hp. Doug
