FWIW our very own Ron Golden built a HOT rod jimmy with some interesting parts, I'll list some quotes from him, but if you're going to boost it I wouldn't reccomend the Hudson rods (beam's kinda thin for that).

I used 308 Hudson rods (8.115" C-C) vs 7.0" stock GMC rod.
1940-50's Chrysler, Dodge, Plymouth rod bearings
Pontiac pins (.984)
Custom JE pistons with a 50cc dome (11.5:1 CR)(very light)

The inline 6 Jaguar rod is 7.7" long, I think, and looks very nice. I don't remember the dimensions but it warrants having a look.

Those were both edited for relevance and space saving, if you want the whole converstion, search 'Ron Golden' for user, 'rod' for keyword and set the search for posts newer than 1 year (I still have yet to figure out how to set it for further back than that).

My, what a steep learning curve. Erik II#5155
