Ted, you are so very right.
We still have to do some fine tuning, driveability is tuned with no issues.

This 391 motor project took 3 months to complete.
Other repairs and issues took an extra 4 weeks diagnosing and waiting for parts.

Ted you and i both know builds like these used to take 1-2 years.
Evan was great to work with very patient.
Thanks

Pete

Thanks Pete, I have to say again, I'm really, really happy with Pete and the way the car turned out. Not only did he do a great engine build, but we addressed a lot of other minor issues the car had. EVERYONE at the Mile event was blown away with how fast the car is, and that it was reliable enough to drive it home from Chicago to Dallas, and then a week later beat on it at the Mile. For anyone that's been thinking about doing a 391 build from Pete, DO IT! Just be patient and let Pete do it right, don't rush it.

So it's been a while since I posted on this, but figured I'd give an update. Was at a dyno day today, and got a couple of runs in. No wideband, so I still need to do another run somewhere with that so we can finalize the tune. As is, it's running very rich with conservative timing, but numbers were 494HP & 442TQ. Pete thinks there's probably another 20HP in it with proper tuning.

Here's a video of the pull:

One, because Pete tuned it to be rich (safe). Two, you could see it/smell it. When you've been around as many dyno runs as I have, it's pretty obvious.

I really want to do this.

Do they still pay good money for a kidney? Maybe half a liver?

It's a great setup, I really love it. It's a perfect blend of streetable power, that sounds mean while being very drivable. I'd strongly encourage anyone that's considering an engine upgrade to do it.
