Exhaust is getting fabricated then back to the transmission shop.

Going true dual 3", no cats, dual electric exhaust cutouts, Black Widow Angry Housewife mufflers (should have seen the wife look at me when I told her lmao), and 12" black stainless rolled edge tips

Yeehaw! Definitely going to need some video of that!

Yeah buddy! Just gave the guy a deposit. He's ordering the parts today, then we should be about 2 weeks out to get the Hoe in

So I found a deal on ebay that I couldn't pass up. It's a Chevrolet Performance 8.0L (488 cubic inch) LFI! Was meant for industrial use, and can run on CNG, propane, or gas. It uses a Gen VI 7.4 block, but uses a 4.250" stroke, forged internals, so it's pretty much a stroked 454!

Motor was used, but it looks like it's hardly been used. Thing is super clean!

Let me know what you guys think!

Drove the Hoe home and my GAHD does it sound beautiful! Idk if video clips will do it justice. Under light to medium throttle, it's deep and throaty, but when you get into it it's raspy and deep!

You'll see it didn't start or idle the best, but it's due to too much fuel pressure. Doesn't always do this, but just need to swap our fuel pressure regulators. I'll get a better video next time, and I'll get one while driving.

EDIT: uploaded a different video
