I'm looking to maybee put a old sbc into my 94 camaro z28. I was wondering if it's allot of work. What's everything that I will need. I wanted to run my stock t56 with it? Will everything just bolt up. Is this a costly project?

I have not done it, but I think its just a bolt in, the bellhousing pattern is the same, so the trans should be no problem. I am assuming you are running a carb, so you rip out the computer and harness, the fuel line wont lineup, but you can cut that under the car, and splice in a new piece, the gas tank has an electric fuel pump in it, you can use it, and put a block off plate on your motor. I am not sure if you would have to regulate the fuel pressure, I think not, because its carb, but you might have to buy something, to make a return to the tank! LT1's were capable of putting in a distributor, so you should have firewall clearance, but I wouldnt run that stock GM HEI distributor that has the coil on the cap, I would go with an aftermarket, so you dont hit the firewall when trying to time it. Good luck.

The Gen 1 engines do not bolt up to an LT1 T56. There is a kit available.

You can't run a carb with a 45psi fuel supply. Definitely need a pressure regulator. The return line is already there for a bypass style regulator. A lower pressure pump would be a better solution.

Why would the fuel line "not line up"? Its got about 3-feet of plastic tubing after it comes out of the driver's side fender well.

It isn't firewall clearance that's a problem with a conventional distributor, its the cowl. Some people have cut out the cowl and the wiper linkage for clearance, others have found distributors that will fit.

Going to a Gen 1 block does not mean you have to go to a carb and a distributor. It can be injected and have a fully computer controlled direct-fire ignition.



But you need an aftermarket ECU, or to keep the LT1 PCM, you need to find a way to mount the optical sensor from the Opti either on the front of the engine, or using a distributor stub. It has been done.

you may want to look at msd's pro-billit low profile distributor...

where can you get this kit because i'm in the same boat? and what did you do about the motor mounts?

If you mean the kit to fit the LT1 T56 to a Gen 1 block, check with Spohn Performance. Steve Spohn borrowed my spare LT1 T56 to help design the kit. He doesn't make the kit, but he knows who does.

its still a very very tight fit.
