Hey guys,
Finally getting around to checking out a motor I picked up that supposedly had been rebuilt recently. Piston bore looks good with no ridge and installer had put in a .20/.20 crank. Also getting ready to degree the cam to see what is in there.
The crank and bearings looked good. I ordered/installed a new set of Clevite 77's and all main and rod bearing specs were within specs. I checked crank end-play (after setting the crank up per posts here for setting the thrust bearing) and ended up getting an end play reading of .0013. I saw specs on this are .003-.0011. Should I be too concerned with this? The crank still was shiny on the thrust surfaces and nothing really looked out of the ordinary as far as the old bearings looked. I've seen posts on here where folks have had much more end play and have been able to live with it. (their engines still ran OK as far as they could tell.)
I want to get a new timing cover for the engine. Taking the info. about the end play into account and I plan on going no faster than 11.50's eventually as a goal, (the roll cage threshold here in Michigan at my local track), should I think about getting a high volume timing cover/oil pump combo, get a timing cover and an oil pressure booster kit, or not worry about higher oil pressure or higher oil pump volume at all for a motor that's going to max out at 11.50's? I see arguments either way about raising oil volume/pressure here and wonder what would be best to do. I see several vendors offer timing covers with high pressure capabilities for $150+. I also see posts on higher volume pumps causing issues with wear in some of the timing cover areas. Any ideas?
