My uncil built this motor and finished a day before i was born, and this is how its help up after 3 generations of my family's men driving it...
Here's some progress pictures of my cam swap, (so far) besides the motor running extremely lean, its in amazing shape, you can still see the honing marks on the cylinder-walls!!!
Still makes 190 on the compression meter.
The carbon build up is quite awful, never using ARCO gas again....ever.
Cam bearings are shot from an awful pitting (no pics yet)
The main bearings are, well, id say another 10k miles, but while im here, why not right?? (Clevland 77's) (No pics yet)
Oil pick up screen did its job and picked up old pan gasket.
One oil return hole was clogged with a leaf, so im sure removing it will just add lube... was makn 60psi strong still!
And thats it so far, will update as i go along if any one cares haha
