LS2 or FI small block?

[parsonsj]

Here's one for ya:

NASCAR-sourced SB2. 355 cubic inches. Turn 8000+ rpm.



Stielow did a carbureted SB2 in the Thrasher, I think. Add some fuel injection bosses, a Holley dominator-style throttle body and go injected.

That would be dynamite.

[Mean 69]

How timely! I am pondering the bullet for the new project car I just bought (a second gen). "Everyone" has an LSx motor these days, they are terrific, clearly, but not so unique anymore. I have a 530+ HP solid roller SBC in my 69, and frankly, it is pretty brash. Full roller, ported heads, forged 383, it idles at 1k RPM, and it's rough. Makes 10" of vacuum at idle, so power brakes are not an option. It's a great motor, I love it, but it is rough around the edges.

Light weight is clearly important, so....... Merlin X block, hyd roller cam, appropriate heads, and FI is the way I am leaning right now. The block weighs less than an iron SBC, and although the rest of the stuff will weigh more (crank weighs ~70 lbs, my SB crank is low 40's), overall it'll still come out attractive. 540 CI, nothing terribly outrageous, and it'll make a simple 650-700 HP with nice manners. It makes sense now that the price of the blocks have come down a bit. My budget is ~ $15k, but that is starting fresh. With a motor already, you could lick this for your budget, or at least really close.
