Dude

I was thinking more of class rules than cubic inch/lb restrictions with no restriction on cubes

We are limited to 412 CID by class rule hence the question if a 3.75" would be avaialble. I am not after a crank "just for me" but thought there would be more of a market for the 3.75" crank

Seems to be a few 400" stock and super stock class racers also. Would an aftermarket crank be legal in any of these classes ?????. "Cube for cube" is the 4" stroke going to make any more power than the 3.75" in a race application with factory iron heads ??? (or any heads for that matter). Thinking of restricted factory type classes here.

Although not a problem with my boat, the 3.75" is probably going to be alot easier to hook up in limited tyre classes or on marginal tracks

I think the reason the 400's do so well in cube restricted class racing is the fact that although we dont have a modern cast iron head the factory stuff with 2.11/1.77 valves vs the oppositions 2.02/1.6 dosnt fare to badly when other "brands" are restricted to factory cubes/heads

Is the RAV 3.75" crank a 3" main deal ???. If theres limited demand for them I supose they will be cheap ??? LOL Anyone have one for sale or any idea on price ??????

I will be running an early (N) 3.75" 350 crank in the boat so will see how that holds up first.
