I remember a certain "Miracle engine" guy, (Flanagan?) that used to butcher, er, I mean 'improve' blocks like this. You get the best of all worlds:
1) The cam/crank gear spacing gets pinched too tight.
2) The pistons, already higher after decking, will now be alarmingly high.
3) About the oil grooves- those appear to be Rich's A.E.R. inserYour transmission will now work automatically. With the lost alignment of the crank center to the ******, the thing will pop out of gear all by itself!
ts, not poured babbitt.
This is interesting. I have a rebuilt engine (babbit), the cam/crank spacing was tight and the transmission jumps out of 3rd when slowing down. In order to get the flywheel housing correct, had to have .001 shim on the left ear and .010 on the right but still jumps out of gear. Have also suspected the rebuilt transmission (by one of the big three) may be the problem. I'm not a machinist. Is there any way I can determine exactly how far out the crank alignment is. Even if the crank is misaligned. shouldn't have gotten the flywheel housing alignment correct fixed the jumping out of gear problem??
