Gonna do a TW-5 build with screamin eagle performance heads that have
a 78cc combustion chamber. Tryin to decide what to do about pistons and
what compression would be safe? Would 10.0 be safe or could a guy maybe
go to 10.2? This will be in an `01 Ultra with final tuning to be done at
World Class tuning.
