To rebuild or not rebuild, that's the question!

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..
Hey, we dont get this from the Arabs do we? Knowing them they probably hold the patent..

-------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,

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.....
