Serious Engine Mods

Hello All, I'm new to the forum,

I have an '03 Sprint that I bought 6 months ago with 6,600 miles on it and I've put another 750 so it is about time to start thinking about modifications (my wife has a rule that you have to drive/ride it for 1,000 miles before you can tear it apart). My question is:

Has anyone investigated retrofitting the 1050 crank into a Daytona 955i engine? Are there issues relative to the cases that prevent doing so? As an alternative, is there any problem fitting a Daytona 955i head on the 1050?

Building the Daytona stroker seems more advantageous because the balancers are sized for a lighter mass. It should be possible to replace the pistons, rods, pins, rings, etc. with lighter specialty parts and get a 1050 with the same rotating mass as a 955, thus retaining the balancers. Yes I know it wouldn't be cheap.

Also if anyone has had their head flowed or has seen flow bench stats published, I would appreciate having the information. I would like to run some simulations to estimate the exhaust system size and cooling requirements, but without some real numbers it is pretty crude guess work.

Thanks and I'm enjoying reading all your comments
