hi every1, i just dropped my block off at the machine shop and they said it would be best if i get custom made 70 or 80 over pistons because my motor is allready 60 over and if they just hone it it might burn oil and may not seal correctly i want 2 keep my original block and i dont want my motor build 2 be half *** so im going 2 have 2 get custom made pistons, what piston company should i go threw? and what size piston should i get? i want this build 2 last 10+ years! i dont race it but i do get on it every now and than, i burn rubber/donuts sometimes and my brother takes it 2 sears point/sac speed way a couple times a year so i want it stong, i really need your guys input on this 1 i have no idea what 2 do about getting custom pistons

Bill Trovato likes CP. You better get the block sonic tested to see if further overbore will leave thick enough walls.

 

sleeve all 8 cyls back to std bore,cost is about the same as GOOD custom pistons.i've done that many times
