Better build?
If you could build on either the 88B or 96B motor, which one would you choose and why? Looking to build somewhere in neighborhood of 124 inch or better.
I have a custom frame in the front room I'm looking to start on soon and it takes the "B" motor.
Thanks,
Chuck

The 96 of course
The 96 has a beefier flywheel and you could just big bore the top end, the 88, you will have to split the case and get a stronger flywheel. I just bumped my 88 to a 98, thats the biggest I could go without splitting the case.

I'd suggest the 96, as you would have the hydralic cam plate, and better pump.
The cases are both good, as the 124" platform, but the later model head castings offer some better qualities for re-working, to accomodate the airflows needs of a 124" powerplant.

You might be able to get a good deal on a 96" removal from one of he guys upgrading to the 120R, or just drop in the Screamin' 120R and be done with it. To me the 120R is a freaking bargain if you're buying new.

Good platform to get off the ground with, but it ain't gonna hang with a dedicated, hand-built powerplant of the same size.

I don't think it makes any difference. You need a new crank for either and it would have to be worked. If the cases are early 88B, you already have the Timken, otherwise more machine work. The heads need porting, so, once again, doesn't matter which heads because you will end up with the same configuration with either one. The cylinders are of no use, so the basic difference will be the machine work required to prep the cases for the new bottom end.
I like the 117" approach, will save some money; use the stock crank but have in "Hobanized". More power than you can effectively use.
Scott does make a good point about the cam chest upgrade; the hydrulic tensioner - roller chain setup is nice but you can upgrade the 88B for about $400.

Pefer the hydraulic over a gear drive? If both motors are about the same for build, I believe I'd just look for the less expensive unit to build off of since either would basically just be stock lower end. Correct?
