A 3.66" stroke isn't all that bad. Here is a Chevy V8 B&S chart with the
engines in that stroke range and longer. Some of these can be made into
pretty high revving motors, 6000 rpm for sure. :-)
325 = 3.780" x 3.62" ('99-later, Gen.III, "LM7" 5.3 Liter Vortec, 6.098"
rod)
346 = 3.900" x 3.62" ('97-later, Gen.III, "LS1", 6.098" rod)
350 = 3.900" x 3.66" ('89-'95, "LT5", in "ZR1" Corvette 32-valve DOHC,
5.74" rod)
364 = 4.000" x 3.62" ('99-later, Gen.III, "LQ4" 6.0 Liter Vortec, 6.098"
rod)
383 = 4.000" x 3.80" ('00, "HT 383", Gen.I truck crate motor) (5.7" rod)
400 = 4.125" x 3.75" (Gen.I, 5.565" rod)
A TR6 had a stroke of 3.74" and they could be made to turn 6000 easily,
even with their old Brit technology and 4-main cranks.
The issue is going to be the quality of the parts, the weights of the
parts, and the design parameters for the parts. And there is where you
may have issues. The motor is a forklift motor, I doubt if it was
designed to see more the 4000-4500 rpm. OTOH you could use it as the
basis for a good motor and just upgrade or rework some parts.
