destroker!?
destroker!? ok soo i want to build a big bore little stroke motor. i love rpms and think i would be one of a kind to have a car rep to 9k (without being a ricer). plans were a 6.0 block with a 4.8 crank. ms4 cam and some prc stage 1 heads has this ever been done before? Is it possible? let me know everyones oppion
9K rpm is risking top end damage- yours going to keep TOP of the line pushrods, valves, springs, retainers, so on and so forth, and even then you shouldnt go that high often- ricers rev to the moon cuz their OHC motors
There is no point in building a short stroke motor unless you are displacement limited by racing class rules. A high rpm (9,000) LSx will need a cam that would be a dog on the street and not really come alive untill 6,500 prm or so. A high rpom cam with small displacement is gonna be like a modified Supra. Limp untill 6,000 or so and then BAM!
And besides, a properly built stock stroke 370 will rev to 7,500 and still be decent in the low-mid range.

Exactly even in the Le Mans series the Corvette revs to 6900 and that is a road course. The need out of the corner, long straights, and so on keeping their revs up 90% of the race.
I mean really what would the application be for because I could not see this going into a DD street car.

But the only viable intak choices for LS motors are stock, Fast, GMPP/Vic Jr. single planes.
