bigblock or smallblock.....
Heres one with a blower. Its not street legal but it does show some options 4th gens have.

Well, I have a BBC and a ls1 with twin turbo.
If I could afford it, I would put a TTls1 where the 427 is in one second.
BBC 550hp 14mph hwy. 700r4 9" 3:50 11:1 comp. - been very reliable
(till I blew the trans)
ls1 TT 700hp 25mph hwy. m6 9" 3:50 only 8# of boost and has been
very reliable, and way more driveable... crazy fast.
cars like Dr. Jeckel and Mr. Hide.
Ok if I could do a aluminum bbc with twin turbo...........
that would be the way to go.

The cool thing about superchargers / turbochargers...
every 14lbs of boost is like double the displacement.
350ci -----14lbs boost---is like-----700ci.
On the plus side also, when your driving mello you can still get the 346 mpg.

which ever I do go with is gonna be sprayed, but I really dont know if I want the extra 100lbs plus a bigblock brings to the table... my father has me rethinking the smallblock option as I can have a more reliable,driveable bigblock that will still make good power on the bottle 
I dont know what the hell to do... I could have the best of both worlds and buy an aluminum block for the bigblock engine, but I really dont want to spend the $$$$ as far as a run down of the car, its a 94 camaro thats gonna have a 25.2 cage in it and stock suspension on a tiny 325 drag radial and/or possibly a 29.5x9 or 30x9 radial slick...jay
I'd go BBC if it were a race-only vehicle.

So with that math
454ci-----14lbs boost----is like----908ci.

I see a problem with your quote, your only pushing 650hp out of your big block, Im getting 700hp out of my small block (at low boost) and I still get 25mpg hwy. Guess all that extra BB weight kills the handling AND the mpg

I said BBC. Mostly because its a track car by the look of it more than a street car.
If its going to be doing a lot of miles and street crap I would say small block. An SBC is capable of laying waste to most everything on the street anyway and probably much eaieier to hook up in less than optimal conditions in addition to being more economical. Likely more emmisions compliant too in mild form.
If you have a dedicated setup, though, then those advantages become pretty irrelevant, and the BBC just makes more power.

I would say a small block would be an easier transition. Also with the technology that manufacturers are developing, Small blocks could make as much power as a big block. Another reason why I would choose a small block is that, for me, it would be a better all around vehicle. It is easier to make power with a big block, but I think that the small block is more versitile.
Either choice would be nice Jay, the small block would be more impressive (low8/high 7's), BBC cars are automatically considered to be fast, and rightfully so! That's a nice Camaro you got there (This is Juan Silver Camaro you just did!) and either set-up I'm sure would workout!, I'd like the SBC! Good Luck! Great job on my car by the way!

glad your happy with the car bro...
it looks like the big block guys are gonna get their way as it's just not cost effective for me to rebuild the smallblock we have for boost... we have a 572 with all good internals with low compression that was built with turbo's in mind, thats what will be going in the car... more then likely i will put that in and hit it with a couple stages of nitrous until I can get some $$ together to put a nice 106mm turbo and efi on it
