gen 2 motor build 1441/1507/1535
« on: November 04, 2015, 10:30:04 PM »
I'm getting ready to build a motor and can't decide what size. I'm looking at 3 options 1441/1507/1535. I know hp depends on combination. What are the gains I'm looking at between the three? (Hp and torque number everything being the same in a perfect world) What are some of the draw backs of running a weld up crank?

I'd say go for the Carpenter 1630. I know one or two folks that have them (Hi Fred) and they are f'ing fast.
Have a Harley, spent lots of money on it, thought I had a fast motorcycle, bought a Busa, realized all I had was a fast Harley, not a fast motorcycle!

I have an "old" style Carpenter head and 1657cc. It runs OK!! :hys: The newer Carpenter head, 1635cc, make more HP than mine.

You are right I'm sure it flies but i'm on a budget and I mostly bracket race with the occasional heads up race with some local guys for very little money. Really wondering was, is thousand dollars to stroke a crank worth the money?

I Don't know what they charge, but Marine Crankshaft is the only place to have stroke your crank.
