this bore and stroke...vs...this one ?????? 4.125 bore...4.000 stroke
and
4.125 bore...4.100 stroke
Besides the 11 cubic inches, is there any DIS-advantage of the longer stroke? Piston speed, oil burn, etc...
Is the 11 cubes really only worth about 16 hp, all else being equal.

I would assume that you would gain more "under curve" tq by going with the longer stroke vs. peak hp. The only disadvantage that I can see is the ring placement being tighter. It's not that big of a deal in a N/A application, but if you wanted to go power adder it might pose a problem if you got to heavy with it. IMO, get as many cubes as you can.

I personally want to go 4.125 bore and 4.125 stroke...441ci But if I have another engine that burns oil like my 436 does, even after a year of daily driving, I'll drive the car off the end of a cliff, with me in it.
Do you have your Harrop yet?

I thought the oil burning problems come from the piston traveling so far down the sleeve that it comes out of the sleeve a little bit and causes the pistons to "rock around", which cause ring wear, which allows the oil to get by after the rings have worn down.

Yes, I've had the Harrop for a few months. Just wish I had the money to get the rest of the stuff I need. Should be done soon though.
