I don't think you realize how much oil flow I'm talking about with this problem and this is with stone cold 20W-50 Valvoline oil what's it like when the oil is at 200 degrees vs about 75? Think...

I didn't run the engine with this set of lifters so I can't say exactly what it would have done to the oil pressure but these lifters were producing a gigantic leak. There were always at least a few...

I dug up an old Competition Cams 836 lifter for some comparison:

This is from a set that was made maybe 5-10 years ago but not before they added the EDM hole(this lifter has that feature). What's...

Building the engine with sensible clearances is the first priority. In a low application I'd shoot for .0015-.002 rods and mains.

The big Ford oiling system is adequate and not a problem. Your...

The lifter in the picture(not taken by me) next to the Crower is not an 836 most likely but it is machined exactly the same where it counts and the oil hole which feeds the pushrod is not involved...

Look at the holes that are in the gasket, see how they compare size wise to the holes in the deck.

The ones in my picture(lifters laying on the block) are the Comp Cams 836 which are machined in the same way as the lifter body being compared to the Crower. It will be very interesting to see how...

The cam having more or less lift shouldn't make a big difference with this problem because the lifter tends to stop at around the same place at max lift.

A friend just so happened to have another copy of that cam and it plotted and measured identically. It's only .387 lobe lift so that means that the base circle is big but that shouldn't effect...

Why couldn't it be the exhaust? He says it just flattens out. I've run that same cam in a 545 on the dyno and it was peaking close to 6000rpm with a chassis header and a 3.5 inch collector into a...

It won't be difficult to make the low compression engine run very well on cheap gas with the right camshaft choice.

I don't think that all 370 engines come with the large snout crank but maybe they do... I do think that 370's are all 2 barrel carburetor equipped.

I doubt it has a burnt valve with only 85,000 miles and an exhaust leak causing one to burn sounds like a fallacy to me. I think I'd be looking at the valve springs closely but more closely for a...
