Just wanting to know what clearances people are running in 1000+ hp engines Here are my questions.
Rod bearing clearance (steel rods)
Main bearing clearance
Piston brand and cylinder wall clearance
Ring type and ring end gap
Crankshaft end play
Thanks folks!
 
this is on my motor I'm not making any suggestions to what any one else should do.
Rod clearence .0025 (titanium rods and rod bolts)
Main clearence .0025
Crank shaft end play .0055
childs and albert z gap( gapped to there recomendations)
venolia pistons ( suggested clearence)
Im not sure what type of power it will make yet but should make over a 1000hp
Its a twin turbo 276 in stage2 block and heads, motor sports crank, solid roller

I have seen buils sheets on indy motors that had .0035 on the rods FWIW
