clean up job on a 408/ Question
after putting about 10k on a motor and deciding to swap pistons (only because of performance purposes) how much would i have to bore/hone the motor to ensure a clean entrance for new pistons?
TIA

What kind of piston change do you want to make? If the cylinder walls are not scored, you may can leave the block in the vehicle, pull the heads and run a carbide brush in the cylinders to clean and give the cylinders some tooth to seat the new rings.

hals73rs is right, the rotating assembly will need to be rebalanced. The reciprocating mass of the -32 cc pistons will be different from the -8 cc pistons. The bobweight will have to change according to half of the difference in reciprocating mass for each piston assembly. You'll need to plan on pulling the engine and disassembling the engine.

what about if i did the swap before the motor was ever ran? could i just use another 4.030 piston as long as the motor had never been installed/ran?
