Fantasy SB build
 

I suspect Glenn will dominate this thread. Here are the rules, only OEM parts (ex. camel hump heads, NOT Trick Flows), not even aftermarket fuel pumps, pump gas required. Ford, Dodge, or GM.

Post your combo and your predicted hp.

Any maching/porting allowed? What about cams? Do they have to be OEM street Cams or can they be "Hot Cams" or factory racing bits commonly available.

Hot cams are cool, head milling and porting is also cool. Just needs a factory casting number. You can oversize valves but they must be from the maker too!

Here's mine:

SBC (Go figure)

400ci, 2 bolt main caps (which are stronger than the 4 bolts for some reason)
LT1 Solid Cam & Lifters
LT4 1.6 rockers
Vortec Heads 11.5:1 compression & ported by Glenn :D 2.06& 1.78 BBC valves, would that work?
Single plane vortec manifold
4150 Holley carb (from a BBC) tuned by me!

450hp ish?

No welding a diesel blower base to a sb manifold to run a 10-71! That's too much 'machining.'

I'd go with the same parts as Adam except I'd build a 383 using a 400 crank and 350 block with 10:1, the Vortec heads with 2.02/1.60 and a GM 30-30 cam. It should make about 450-475hp with 450-475tq.

Another fun one would be the same parts only use a 283 crank for 302ci. It should still make the same HP but it would be at 7000rpms instead of 6000. It would also only make around 385-400TQ.

I don't think the LT1 cam would have balls up to 7K.

Probably not but the GM 30-30 does. Both Crane and Comp Cams make new replacements for it and the Comp one shows an operation range of 2300-6900. It has 247/254 at .050 with .504/.498 lift with 1.5 rockers on a 112 LSA.

By the way, when you say OEM parts does that include GM Performance parts and FRPP?
