Yes it was in at the factory specs and 108 degrees. All seemed to check out ok. The crankshaft, after checking for TDC, has 16 degree advance in it. I think thats normal? I know the old engine didn't have the best compression (100-130) but still think it should have run better. Came on strong after 2500 though. I have another, non blower cam, or unknown lift. I think while I have the Block on a stand I'll check it out too. I hope to ground hop the engine in a few days and see what it has for compression at 4 degrees advance. Chuck in NH

I think there were some other issues with that other engine, though. I had the same cam in my 60 over 292 and the low end was good. But it did (and still does with 17 more cubes) feel like it comes on between 1500 and 2000.

Was yours at 108 in the 0 advance keyway of the crank gear? I had to use the full 8 degrees of advance and mine is still retarded 2 1/2 degrees. This makes me believe that it was quite retarded in the old engine, though I never degreed it. I compared the cranks and the keyways appeared to be indexed about the same.

I did degree the cam and it came out to the 108 centerline as advertised. The engine is on a stand so cranking compression isn't a current option. I'll go 4 degrees advance and see what happens. We all know what a pitiful low end, even with 3:80 gears, the old engine had. It was a 40 over 292. Thanks again, Chuck in NH

Ditto on the four degrees of advance.  Two degrees typically doesn’t show a step change in performance unless the camshaft is already borderline in being too big.  I’m assuming the camshaft was originally degreed in?  If not, then it’s a stab in the dark on the advance as you don’t have a baseline to really base it on.  A compression ratio check before and after the cam advance change will also validate the change by showing you an increase in cranking compression but if this is being done on an engine stand, then 'never mind'.  And John is right as usual in that a higher stall converter will undoubtedly be the best bang for the buck in this case.

It is one of his blower cams. I just couldn't get used to the idea of missing the timing to get it set right. We'll see how this one runs. Chuck in NH

Chuck, you got it.  I had lost my instructions when I degreed mine.  Couldn't figure it out.  Had to call Mummert.  Is this one of the repro blower cams he offered several years ago?  The specs are curiously similar to mine.

Just for clarification on the timing advance I've attached a sketch of a crank gear, actual dot locations may not be correct. If I want to advance the cam by 2 degrees am I correct to move the crank pulley from the stamped dot to the 2 degree adv location (imaginary dot in red) and also relocate the timing chain to the 2 degree adv tooth (imaginary dot in red). Thanks, Chuck in NH

I'll be putting in an AOD with a 3000 stall converter this time. Chuck

Chuck:

The best help you can give that 272 is a higher stall speed converter.

The 272 is 40 over and decked and balanced with ECZ-G heads. I have a 4" and a 5" pulley for the McCullouch so I have a little boost adjustment. The 4" puts out 6-8lbs of boost with the improved impeller. The last engine was a 40 over 292 with the same set up and cam. It had no torque at low end. Wouldn't break the tires loose for anything (except maybe wet pavement). I've got a big 292 block coming in the fall (3.875 bore) and will probably build it this winter. Just want the little 272 to scream until then. Is there a better cam for this setup?Chuck in NH
