[TPR] Checking the specs,Asa's current Mach I engine

[Asa Jay Laughton]

Honestly Russ... it's been 10 years now.  I'm beginning to even wonder  
if the initial oil -was- non-detergent.  I -know- it wasn't synthetic,  
but that's the extent of what I remember.  I probably ran it for about  
500 miles and then changed the oil to whatever I was using at the  
time.  I think it was an off-the-shelf synthetic blend from Napa.  I  
moved back to Amsoil about five years ago.

I couldn't tell you what the clearances were, except to say they were  
within factory specs at the time.  If that means low end or high end  
of the spec, I don't remember and apparently didn't document it either.

One thing I didn't do when the crank came back, was to make sure it  
was clean.  I made sure the journals were nice and clean but...  I  
didn't run a bore brush through the oil holes in the crank and I'm  
betting there was debris in there I didn't know about.

The carb will be the Holley currently sitting on the Pantera, -not-  
the Carter AFB that was running extremely rich on the Mach I.  The  
Holley is already tuned pretty well for the Pantera... though I may  
send it out to be rebuilt to the engine specs I'm putting in.  No  
budget for that currently though.

The cylinders still show cross-hatching, even so I had planned on  
borrowing a ball hone to run in the holes prior to assembly.  The  
rings still have gobs of tension.  I hate to spend even more money I  
hadn't budgeted, on rings.  What's the downside of using them again?   
Especially if they didn't seat the first time?

... and further to that question, what rings would you recommend?

Thank you,
Asa Jay
