today i picked up a stock appearing motor for $200.00, the gentleman i bought it from told me that it is a predator Hemi block, Ambush racing 34 degree flywheel, clone crank and arc billet rod. He said with that combination of crank and rod it was a stroker. he also said that it has a 4hp head that is ported and polished. ( which after running the numbers on the head, i believe what he meant was it is a 14cc clone high compression head) it does have a flat top piston with 32lb valve springs and a holy mosses carb running on gas. could anyone help enlighten me on this set up? also he said the motor was showing 19hp on the dyne. is that a realistic number? Also i am planning to build this into a open class motor, would i be competitive if i just swap out the carb for a Mikuni on Alky. Thanks in advance for you help.
