Mild 383 build
I appreciate You digging for relevant dyno tests, & the amount of mass reduction doing a stroker varies combo-to-combo, but yes it is often overlooked.
Not mass, larger piston more surface area for force to be applied. When people see a 400 B engine vs a 408 they see 4" greater torque multiplication over the 3.38", but fail to recognize the greater force the 4.34" piston will have over the 4" piston to be multiply by the crank in the 1st place.
The 2 primary statements fishmens67 made were; no less than 3,800 stall,
Again never argue against his 3800 stall recommend or for the OP to run a 292 cam.
& that Your math doesn't add up in the real world....referring to the projected bump/CR increase...which He is 100% correct on both points.
He gave no CR numbers to work with, I gave a half joking shot in the dark answer to a question I wasn't even talking about, again I was talking about torque and cid.
Plus I don't see any evidence I'm necessarily wrong, the cam specs for the xe285hl and Mega 292 are fairly similar, 9.2 cr ain't considered high compression the engine at 3000 rpms is still making more than stock and we don't exactly know how much gain going to 10-10.5 from 9.2 will add, rule of thumb is like 3-4% maybe is maybe it ain't, all I know fair size cam in this relatively low cr engine didn't kill the bottom end.
I got a 360 (380hp crate). 9:1 cr 288/292 cam 108 2800 stall and 2.94 gears is it the best it can be no, still burn rubber and is fun I'm sure more stall and gears will make night and day difference but till then it is fine. Not saying/recommend the OP should run a 292 cam with 3000 stall and 3.73-4.10 gears but if he did probably wouldn't be the end of the world and can always do a converter swap down the road.
Everything doesn't always have to be prefect from day one.
Can we move on now?
