i have a 75 280 w dished pitons that are .050 over. i would like to use flat top zx pistons. A) can i use .050 flat top pitons & new rings or B) do i need to rebore again & use the next larger size( i'm not sure there are larger size pistons are available after.050) i'm trying to boost compression for better low end performance.
it all depends on how worn your block is....these blocks are very tough...how many miles were on the engine after the .50 rebuild? you can get 1.00mm over bores...check taper w/ telescoping gauges, and see. good luck
