I just bought a car with a fresh professionally built engine. It's a 1969 Pontiac 461 stroker, a Butler Performance kit. It was assembled by a local race shop for the previous owner in TX. They did 2 or 3 pulls on the engine dyno and now it has 100-150 miles on it since being installed into the car.
I looked up the Butler kit and it uses Total Seal rings, so I don't think they are moly rings. The block had ALL the prep options done to it going by the paperwork. It's .030" over with a proper machine shop cylinder hone. After the initial cam break in (it's a hydraulic flat tappet) and engine dyno pulls (not sure what break in oil was used) it was then filled with Brad Penn 15w40 according to the paperwork. The engine is carbureted but since it was engine dyno tuned I don't expect it to be running so rich that it will have an adverse affect on the cylinder wear.
I am flying to Texas on Monday to drive the car back to CA, so the engine will has just over 2,000 miles by the time I get her home.
My question: Is that enough miles that you would feel 100% great about switching over to Redline? Or would you wait until how many miles, 3,000? More?
Thanks!!!
