We can typically deliver had an engine ready for delivery within four weeks of the order. We offer five engines categories.

• High Performance Street: While both more dependable and more powerful than what was delivered from the factory, these engines offer a smooth idle and good vacuum on today's lower octane fuels. The reconditioned blocks are precision machined, the rotating balanced, and the irons heads receive a Stage I porting. This category of engines have a hydraulic cam for ease of operation and roller rocker assembly for less friction. All parts used are at least as good as original -- and most are better.

Custom Race Carburetors

While Diamondback Engines is mainly known for its Race Engines -- many do not realize that we also build the best racing carburetors. How much is 2/10 of a second worth to you? Many racers have a killer motor, but slap an out of a box carburetor on top of it. That's like a Golden Glove baseball player with a $2 arm! Too many racers are leaving a lot of speed on the table with a poorly built carburetor.

In the sidebar to the left -- you will find links with more specific details. Give us the call, and we will build a custom carburetor for your car and your racing class. It is not unusual for racers to pick up 2/10 of a second and more. Diamondback Engines builds custom carburetors for gas or alky; for drag or dirt track racers; 4150, Dominator, or AFB; and for automatics or sticks.

Attention Nostalgia Super Stock Racers!

Or any other class requiring an AFB carburetor. Here's Your Advantage

Diamondback 800 AFB Powder Coated in Black

One of the limitations of running a Mopar Wedge Motor in Nostalgia Super Stock (NSS) is that your carburetors have to be of the AFB design, and no larger than 850 CFM. Most of the original Super Stockers never learned how to turn this disadvantage into their advantage -- but a few of the best ones did. Damon was taught much of what he incorporates into the Diamondback AFBs by a pretty famous S/S racer from the 60s/70s -- and then he improved on that foundation. While you will immediately recognize the mill work to remove the choke horn and to make it breathe better -- there are quite a few unseen tricks that make these the choice of the faster NSS cars required to run AFBs.

We start with a brand new Edelbrock Performer AFB 800CFM carburetor, disassemble, mill, and reassemble with tricks geared towards the 8.50-10.0 second racecar. Automatic and manual transmissions require a very different AFB carburetor -- so we make a DIA-800AFB-A for the automatic transmission cars and a DIA-800AFB-M for the manual transmission cars.

The below are four cars that you might recognize, which are running a pair of the Diamondback AFBs
