This will be the 4 year on the motor in 09, but it could also be the last? There was also a little nitrous there to help me along....hehe!

It seems this is 50% of the failures, the other is the main caps breaking. The after market stuff helps in this area, but nothing can be done about the cylinders...Im sorry filling the block doesn't help [color:"red"]65 Hemi Belvedere coming soon [/color] [color:"#00FF00"]557" Indy engine 1.07 60ft 144mph in the 8th 2100 lbs package [/color]

Actually never broken an alum capped block. Definitely not saying you won't break one, but I never have. Monte

I guess I should have asked before I bought my balanced rotating assembly.

I have been thinking about a procharger set up.
