The testing we did on my motor showed no gain going from a 95 to the 103. I made 705 at the crank just for reference.
I ported my own MSD also, watched a couple of videos and picked up a couple die grinder bits then went to town. The Holley Hi ram is the new buzz word but the MSD does hold its own up to 7k rpm, it leaks like a bitch so rtv that sucker when you're done.

To make 705 crank you probably are stroked to 7L (427) right ?
My interrogation is will a 95mm non ported be better than a ported 87mm ? The 103mm are expensive also, at $650....
I'll take a look at porting the MSD...thanks. When you say it leaks, where ?
