If I was trying yo determine the most important valve timing event, I would be trying to find somebody who has tested thousands & thousands of cams.....& did so without any pre-conceived ideas about the results. I only know of one such person who has done this. And he found that IVC was NOT...

Wow! Such a remarkably gracious intro! Perhaps you aced a Dale Carnegie course? Ya know, you've joined-in on a site where there are lotsa rather knowledgeable, experienced guys; including a well-respected & successful cam designer-manufacturer. Good luck in your endeavors. Out. Well, the initia...

How would it be the same if it's a flat head engine?

it will run pig rich with a blown pv at idle it won't run pig, cow or chicken rich with a blown power valve. It certainly will run super rich with a blown power valve because fuel goes right past the diaphragm in it, directly through the vacuum supply hole for it. i stand corrected......i should ha...

the right dampener will actually gain you power. i did a bunch of different Damper tests for Troy Coughlin's (Jegs) NHRA ProStocker in 1994 ATI , Rattler, Fluid Damper, etc. and then i personally did a bunch on various engines i had in my Shop -vs- no Damper you will always loose TQ and HP if you r...

You got a picture of these OEM carburetor intake manifolds that are made of plastic? Got and pictures of you laying on the hood fingering your tunnel ram as the car drives down the street? I'd pay to see that ha ha. I see from your comments with your apparent limited , real world experience, a keyb...

You have tune the idle circuit richer and the primary jet richer when running a cold manifold... Fuel vapourization requires HEAT INPUT.. You get BETTER vapourization around town with a little added plenum heat. Thats why every OEM uses intake plenum heat. The exhaust is cleaner. The plugs last lon...

You can use spacers to drop the K-member down to gain clearance for a better intake. The intake isn’t changing. I’m trying to pick a carb I think the intake you have is about as good a choice as any. I'd avoid the 830 carb. I understand your idea of the annular boosters to compensate for the poor t...

Its a old Coronet not a vette. It will take a high rise intake with correct aircleaner. The Edelbrock Perf RPM 440 intake is the best single 4 bbl intake for your car . Especially with a generous carb. Time to move out of the '70's. All the low rise single planes are bad for your car setup.. I have...

Good grief. In mid-1971 a few select Chrysler high performance engines got the electronic ignitions. By 1972 all Chrysler performance engines got the electronic ignition. By 1973 ALL Chrysler engines we're electronic. since I didn't personally see all of the 1972 performance models that came out I ...
