412 Stroker said
Newest issue of Popular Hotrodding, has SKMFX Engines (from Canada) built a W2 headed 360 I think it was .040 over 360 block, 519 hp and 476 torque, the builder says he doesn't like strokers as they pound the crap out of the mains, can anyone confirm this?? I had not heard of this, how is this possible, I am new to the stroker stuff, I have heard some getting over 10,000 miles on thier stroker, to me thats seems good life, especailly if you pound on it. the way I drive my car 10,000 miles is like 5+ years as I only get to drive my duster about 2000 miles a year.

That was a competition engine for the Engine Masters. Those engines usually see alot of detonation as they push them to the edge of destruction. Last year over half of the entries failed on the dyno!
I have not seen any evidence of strokers hurting mains unless there was something else wrong. The caps will walk more because of the added stress the extra stroke makes but it's not a problem unless you have detonation.
