Oh yeah, I remember the Chevy 305. A 350 with decreased bore
but the same stroke. Never understood why GM did that. A much
better idea is to keep the same bore as the 350 and increase the
stroke from 3.48 inches to 3.75 inches (400 crank) to make a 383,
which ought to be well over 400 hp.[/quote]
That's the plan. If I ever freeze crack, blow up, wear out, or otherwise get sufficiently bored and have the money sitting around, the 305 will be replaced with a 383. A 200 hp jump should be a hell of a thing. I can nip at 50 mph with the 30 year old stock engine so would hope to be well into the 60s with a 383 and the right prop. I think the Alpha drive will survive as long as I don't pound it too hard out of the hole. A Bravo 1 would be awesome but it's a damn expensive upgrade.
