The X-over is part of the Magnaflow exhaust it looks like it necks down a little From the 3" exhaust. I would guess its a 2.75 in and out.

I have already done the Swap. This thread outlines the process from the beginning. Here is the Face book page.

I've been following this build on Facebook on the C4 corvette page. Tea this build is awesome. I thought you were building a 6.0L though. I almost got me a 5.3 w/ all electronics for $400 last week but the guy sold it out from under me. How did you solve the windshield wipers problem?

I didn't have a problem with my wipers. My C4 is a 91.. the wipers are a little recessed in the later body. My engine is a LM7/5.3 but it's bored to 5.7 346CI with forged internals. It was done almost 2 years ago and made 400RWHP on the dyno.

Let me know if you need any help.

The only reason I don't have room for the wiper motor is the Holley LS fuel rails I'm using. They put a fuel fitting where the wiper motor fits.

PS
I also think the engine is about 1-1/2 Inches father back.

What intake? Heads? Cam? Throttle body? Fuel rails? Injectors? What else had to be updated? Did you change internals? I have so many questions.

Heads? Stock LS1 241
Cam? TSP MS3 237/242 .603"/.609"
Throttle body? Stock ported 99Z28
Fuel rails? Stock ls1
