A classic truck needs, a classic motor!

In-line 6 with running issues out and a stock 350 in!

Bone stock 350 with a set of Speed engineering stainless steel long tube headers and a custom X pipe axle dumped 304 stainless steel exhaust!

This truck is a perfect running and driving and now incredibly reliable truck that Troy and his wife Katie can now enjoy the way they intended on enjoying the truck ever since they bought it!!

Clinched another 1st with our shop pull truck in the comp efi class securing the points lead for now.

Took 3rd in street open, can’t complain about street open the trucks that beat us have double the horse power and double the displacement.

We will continue to tweak the truck to hopefully hold our lead for the rest of the season.

Abe is back with another build!

We hooked him up with a set of brand new BFG all-terrain for his new aluminum rally style Chevy wheels!

And we also got him sounding just right with a custom 2 1/2 inch stainless steel equal length exhaust! 

I must say, especially being a big square body guy at heart this square body is looking pretty damn good right now. I can’t wait to see what it looks like when it’s done!

Don’t forget, we are a tire dealer, and a Custom Offsets dealer. We can get you pretty much any wheel and any tire you need!

We can mount and balance your wheels without a single scratch!!!
