Hi Guys,
Silver top / black top later modle info.Any chance of some pic's or other info. Pin height is there any difference. Piston shirt depth below pin?
H beam or I beam rods. Crank journal size one bigger than the other? Cam Journal size one bigger than the other?
Rocker gear does one have less off set with a straighter push rods.Size of push rods? Valve size and duration?
Are both engines 22.7 to 1 comp ratios.
Don't want to know the weights or sizes just yes / no.
Tony may know all this stuff, picked up on the later black tops have lighter pistons which makes them smoother.
Thanks
Kel
