Hi Chris,

Thanks for the information. I have not really used a ton of these blocks for race engines, a few but not at this kind of rpm

I usually use a 2 bolt main, filled with hardblok with Milodon splayed main caps (which i thought about on this one)

Being this is what i would call more of a budget build i thought about using the domed pistons which are 480gram, that would allow me to keep the 329gram pistons to save a few $ for a super light aluminum rod (about 435gram rod)

Im gonna use my Comp cam which is HXL intake lobe and RZ exhaust lobe. 307/317 @.020" 278/284 @.050" 201/197 @.200" .726"/.660" with 1.6/1.5 rockers 106 degree lobe seperation
