I used CGM Motorsports in Millerville, MD. The owner has a long history of building high quality race engines and a couple of the machinists in the shop are outstanding. My carb, Holley 750DP, was overhauled and custom built to my application by Baker Outlaw Fuels and the Dyno runs were completed in PA at Baker Outlaw Fuels as well.
I have video of the engine on the Dyno, but haven't figured out how to put them in this post yet, but am working on it.
I will be putting the engine in my truck in the next couple of weeks. (I hope)
Next project will be to have a custom exhaust installed.
The PO had headers and a crossover exiting in front of the rear wheels WITHOUT mufflers, just resonator tips. I am going to quiet it down a bunch and have the exhaust dump just in front of the rear axle like an old '67 GMC is used to own in Arizona.
PM me if you would like some more details.
