Try running with the gas cap loose. The vent could be blocked and causing a flow problem.

Just for conversation sake, how much oil leeched into the valve chamber during the test? This would tell just how much oil is directed through the filter.

Just a quick note to let everyone here know that I am still operating and don't know why Google lists my business as "Perminately Closed". I can assure everyone that I am very much open and working. So much so that I don't have much time for message boards so, to get in touch, you will have to...

The bolt pattern diameter is 10.375. The holes are 120 degrees apart with a separation of 32 degrees between the two diameters.

Try this

I have one exactly like that. Nice head with a high compression but is extremely heavy. Probably a third heavier than a stock head. Until now, mine is the only one I have ever seen.

Could also be wrist pin rattle. I vote for the center main.

Look for the timing pin under the pulley. If the PO forgot to replace it, that's most likely where it is. As for the backfire, it sounds like you have an intake leak and a rich carb. What carb are you running?

Permatex #2. It does not get hard and will stop the seepage. I find many blocks that have the head studs drilled or rusted into the water jacket and this works unbelievably well. Does not harden to the point that the stud can not be removed.

How much rotational play do you have in the distributor cam when in the motor? Are you running a stock original cam, regrind, or a new cam? The gear on a stock or reground cam all have some wear on them and can let the distributor shaft float rotationaly which, will change the timing according...

Sounds like the builder didn't know how to rebuild the B engine. The pump in an A or B has the capability of as much as 100 PSI but without any restriction in the system, it won't push but about 2/3 # in an A and 5/7# in a B with the stock system. There is a marked difference in the A bearing...

Cast iron pulleys fail from using pry bars to install or remove the engine. I use lots and have several originals that are perfect except for the seal area being worn. I don't see any reason why a cast pulley would just fail from running. Operator error. The only reason to use a two piece pulley...

If you want babbitt bearings, you won't get them at AER.

I would drop the pan and inspect the bearings and check the clearance. The last 2 engines in my shop had bad bearings and a pronounced knock at higher RPM's. One had a bad rod bearing and showed lots of bearing material in the oil, I replaced the rods and polished the crank to repair it. The...

After adjusting the bearings to the correct clearance, this is often the case. Put it in and run it. After a couple of minutes it will work as before but with better clearances.
