duncan motor

[LONG-ROD]

just was wondering what it might be worth. the complete motor. L.A. sleeved 310 at 67.50. duncan cool head with 19cc dome. 210psi. polished clutch cover, chrome powder coated stator cover. only has had vp 110 ran in it. 39 pwk carb. pyramid reeds. brand new clutch plates. new mechanical seal. new oem crank. excelent motor,

also should mention has Duncan national mid rang port job.

i would say, with the carb and all the other extras, around $600-700. but then again, polished covers are not cheap. so with all the bling i would say $800-900.

If its got a 67.50mm bore it not a 310.

[deathman53]

its something like a 259 with that piston. 68mm is ~262 and stock bore(66mm) is a 246. If its a stroker motor, then it could be 300+. Many people don't realize most 310's are 72mm X 72mm, that makes a 293cc. Only at the last bore of the cylinder 74mm its a 309cc.
