I have a 383 in a 78 chevy that I wanted to put EFI on it. I modified a LT1 intake manifold to work with it and got megasquirt to start the motor.

I bought a 1999 suburban with a bad motor and bought a core to rebuild, I am sitting with an extra vortec manifold. I like the looks of the vortex manifold better than my cobble job.

The 383 has 11:1 compression, dart iron eagle heads and an RV cam which I can't recall the specification on.

I have read the 411 ECU is a good ecu and it would allow me to put an over drive transmission in the pickup as well.

I am looking to see if anyone knows about any pitfall I might run into or if the LT1 intake is a lot better and I should just deal with the fact it isn't pretty.

Before I waste a lot more money and cutting stuff up, I thought to get some input.

Thanks
