Its an LS1 and done. I finished it about a year ago but was still having some trans issues. They have been resolved and the car is street legal now.

I say it's done because the swap is complete but the car is not done yet. Prob never will be, I want to do suspension and rear next.

Whoa my eyes..
Give me a minute I'm going to kick my car real quick.

Just Yes.

That's all that needs to be said about the ZR-1. Yes.

BTW: Had it out at CotA a few weeks ago and the instructor riding with me said "I didn't think C4's could do that..."

I said "MOST can't!"

It's pretty stealthy...

Unfortunately no dyno sheet yet, so i cannot say but I can say yes I modded the hell out of mine so I could be the loud, obnoxious, almost 50 year old living in my town. Which every one talks about will never grow up and is going thru their 3rd child hood and mid-life crisis, but oh yea his car is cool!

As my log on say, I am new to corvette and definitely new to C4, is that a stock engine. That one awesome looking machine under the hood. I think I just change my mine on which model to get for next C4.

This is a stock 405hp LT5 in my Yellow 93 ZR-1, the one in old blue 91 ZR-1 has been refinished and has mods listed.

I think randy ransome puts us all to shame!!!!

ch@0s

That is impressive! Good Job.
This really goes to show that a well thought out L98 can perform.

The truth is being stretched really hard in this thread.

1991Z07

Just waiting on some time (and open space) to start on my '92 ZR1-bodied track car...

Intending to drop an LS7 in it...full cage, C6ZR1 carbon/ceramic brakes...

Got a huge job scheduled out for the next 4 months...it is certainly paying the bills, but I don't think the car will get started until fall now.

Just dumped a ton of money into getting 300rwhp into my beater Civic.

That being said I haven't done too much to my car just yet. So far the list is X-Brace, Camber Brace, muffler eliminators, skip-shift delete, and splash guards. I'm currently collecting parts for a cam swap. Hoping for 370whp

You mean we were supposed to tell the truth???

I appreciate the compliment but I can't take all the credit for my motor.

It was already somewhat polished when I got it but it was clear coated and it had turned Yellow over time. I just stripped the clear and did a resand and repolish. Thanks again.

I like your yellow Z.

ch@0s

I keep waiting for you to start and post up.

I cant believe i missed your post..more details please?
