Feedback on these cam specs.
Comp cam told me that cam runs between 1800rpm and 5600rpm range. I purchased some pacesetter longtube offroad headers. I am hoping to run high to mid 11 sec passes at the track with my setup.. I am switchin to turbo 400 trans with a 3.73 gear with 10 bolt. oh, and run a neil chance 3200-3400 stall.
With the dual plane intake they are likely right, BUT understand that for an LT1 with an LT1 intake their rpm ranges are WRONG. The short runner LT1 intake shifts the rpm range up fairly significantly, trusting the tech line has caused a LOT of troubles for a lot of guys. Yes they have skilled engineers at the company, but they aren't the ones answering the phone flipping through the same catalog you could have looked at yourself without wasting your time calling them.
For a street car I would really consider a 700R4, lot better first gear, plus overdrive so you can comfortably run more rear gear, plus lockup so you can comfortably run more stall.
I know when I go to the track the musclecar guys all droll over the performance and driveability we get out of the later model stuff. Yeah the injection is some of it but you decided against that already, but the tranny really helps too. 3.06 first gear to the Th400s 2.43 plus as I said with the overdrive and lockup more stall and gear are just fine on the street.

I know the OP wants a carburetor but for the life of me I can't figure why. I grew up wit those damnable things and have tuned about anything that sucks gas for over 40 years. Webers, Dellorto's, Carter, Holley, Rochester all of them.
Modern Fuel injection is far superior for driveability while making all the power possible over a wider RPM range. To go from a precisely metered fuel charge to a semi-regulated gas leak is quite the step backwards. IMHO.

I good friend built a 331 Ford Stroker that makes 380RWHP in a mazda Miata (friggin wicked fast BTW) and carb'd it for the "classic" looks and performance. He is constantly trying to dial in the carb and keep it dialed in as climate conditions change and is now wanting EFI put it will cost close to 2K to do it. Carbs look cool and run awsome when dialed in but messing with them to ensure optimum peroformace, unless its a dedicated strip car, is no damn fun.

Your friend with the Miata sounds like my kind of guy.
I'll put an LTx engine anywhere it will fit but I keep the injection. There's just something about ricers powered by American Iron that is cool. How's about my old beat up "Z" car? The open differential is quite an issue but it sure is a lot of fun. Sitting at traffic lights it cool to see the other drivers looking around for the car that's making that "Rumbling" sound.
I'm trying to figure how to replace the Kohler 25 horse on my lawnmower with a LT1.
Sorry for the Hijack but I couldn't pass this up and I have already gave some real good advice.

I agree carbing an LT1 is extremely foolish, once you do that all you have is a gen 1 motor with vastly reduced intake selection and a more expensive waterpump. The port injection is a critical piece of what it is.
Then again even as an LT1 lover I don't understand why people bother putting it in retrofits I would jump straight to the LS variants, 5.3s are just as cheap, the swap market is very well supported.

Lets not be snarky now
Now if we can just get Dwayne (96capricemgr) to smile and take a sensitivity training class we'd be one big, happy Corvette family. ;-)
Its really disrespectful and no one is entertained Mr. Jester
