I am going to go against the other LS1 swappers out there and say GO FOR IT. Sounds like a cool project.
I am using a driver's side vette manifold and a passenger's side F-body manifold for now. I have a set of long tube headers I am modifying to fit. Oh yeah, and cutouts.

As for the manifolds, does the engine sit in the same location as a Gen I? If so, couldn't you cut a LS1 exhaust flange and weld it to some Gen I headers?

budman, are those the same flanges GM sells, or are these thicker? The nice thing about FI is the flexability of the system. Some guys are running unthinkably large cams and their cars are still streetable.

This is a swap project that never happened...because of cash....I get to benefit (I am getting the motor checked
)
The reason for the CARB... a it will be cheaper than the fuel injection ( I am paying for this job to be done..SORRY GUYS DON'T HAVE THE TIME TO DO THIS ONE....or the patience)
1) it will be different
2) have you seen the lastest craze with muscle cars and LS1 motors?
3) it will KICK THE CRAP out of a GEN I motor
4) the car came from the factory with a carb?
5) I have a carb already
6) less wires and no computer in a already cramped car? MY car doesn't have a gove box... BUT A MAP HOLDER....
Yeah it would be cool to have fuel injection... but this will make my car unique and those who don't have a CLUE will be shocked!
what do you think?
and manifolds.... corvette ones work??? yes or no?
no shorty headers here...manifolds will do. I have no cats and mid america chambered exhaust...

By carbing it, you are getting rid of a major advantage of doing the swap in the first place.
Since I have both a C5 and L82 C3 (actually the C3 is the wifes car) the main difference I can detect is the magnificant throttle response at low RPM WOT... and partial throttle response the LS1 FI gives.
The PCM FI setup on the LS1 always gets you the proper fuel mixture during any... and all partial acceleration scenarios - during all air temp, water temp, and weather conditions.
And then going WOT ... you don't get so bogged down at the beginning when the RPMs haven't climbed above 3500 yet.
I have an Innovate WB AFR setup and the LS1 fuel management system is truly amazing. Of all the previous systems placed on (pre C5) Vettes, I think the General finally got one right.

Well as far as trannies.... a got a viper spec T56 with a stage III spec clutch and all the fixens.... but I have it sold ( i believe) I am sticking with the TH350 for now...ARGHHH stop the flaming
I will be running a 2400 stall...looks like I may upgrade to a 2800-3000 with the cam...
I am trying to keep it simple and inexpensive...
MANIFOLDS..... Looks like or sounds like any of the factory ones will work... I prefer ZO6 02-04 manifolds if I can get them... they flow the best out of all the other factory ones... I saw that in the recent hotrod magazine...
As far a out running GEN I motors... I think (know) I will have edge on them for the mods I will have...IF YOU DON'T know this yet... you will learn it from one of the many heads and cam GEN III motors out there.
I am willing to bet that I will out dyno any factory ZZ4 or fast burn engine....which is basically a heads and cam GEN I

Im pretty sure the z06 manifolds are the exact same as the normal c5 ones.

With that cam, forget the Edelbrock setup. GM has a single plane carb manifold for the LS1 and MSD will be selling the ignition setup separately. MSD builds the Edelbrock version but their own will be much more tuneable (may be via laptop).
For the manifold go to www.sdpc2000.com, LS1/6 parts
Ignition www.msdignitions.com New products
If you can find a copy of the Winter 2004 Engine Masters magazine (Popular Hot Rodding pub), there is a good article in there.
I was thinking a carbed LS with my Tremec but I like the sidepipes too much (and no $$$) so I am sticking with the Gen I for now.
