By the way, I use Mobil One synthetic religiously in all of my street and race cars. They were first, they are they are the best. I punish my equipment much harder than most enthusiasts and have never had an oil related failure.

Our overall fuel bill went noticably down when I switched all the trucks to synthetic,it more than pays for itself in the short and long run.. https://www.yenko.net/ubbthreads/imag...s/headbang.gif

-------I have nothing against Mobil 1. I also cannot account for my experience, just an anomalie. I guess I may have broken my 502 in incorrectly as I had to make a run to Carlisle within about 300 miles of installation and took the break-in oil out at that point and went to Mobil 1. Maybe things didnt have a chance to seat correctly??? For the period after that trip until I changed back to regular oil people thought I had installed a diesel in my Suburban. The lifters were unbelieveably noisy. Since I have never even had the valve covers off this engine I have no idea how it is wearing, but am very interested in seeing what the inside looks like when I do take a look-see.........Bill S

I always did the swapping after the first 2,000 oil change and never had a problem..then every 3k miles after..

Yeah, Mark I would like a high rise manifold, but the only way to do that would be to get rid of the shaker hood or modify it by bolting/welding it to the hood. That would be ugly

Yep, if I do rebuild it this Winter, new valves, guides, seals, springs, retainers, hardened seats, and a mild port and polish job.

Thanks,

John

Hardened seats are not necessary. Maybe with a monster cam with huge seat pressure. But on a stock street motor, keep the valves adjusted and it will be fine.....
