Thanks for the info Frank...FYI, I've been running premium gas
all along....This old engine deserves it...It sat idle for over
8 years and surprised me when I first got her running again..
I am using 15w40 Rotella oil, changing it every 1,000 miles or
so. The engine will pull smoothly from 1,400 RPM in 3rd overdrive on a freeway uphill......So, it puts out gobs of torque

I'm just looking into a little more poop @ 2,500 RPM.. I put
the 2 barrel Weber on it, petronix ign module and advanced the
timing to 12* BTDC at idle...No pinging or hard starting..

When I get a chance, I'll pull the head and oil pan and inspect
the general condition.... Then, I'll either mill the head and
reassemble or, pull the engine for a major overhaul... It runs
so good right now, it's hard to make working on it a priority.

I've been screwing around with old cars for 50 years and this
engine is the smoothest, torquiest little motor I've ever played
with..
Thanks Again,
Larry aka, Melon
