A/A 21 Pro Engines

[Al Hobbs]

Here are a few photos of the A/A 21 Pro engine parts.

The billet crankcases will not be finished until I receive the pistons and sleeves from the NOVA factory. I've been waiting 6 months forw the pistons and sleeves.

Also picture are the A/A 21 Pro carburetor barrels.

All USA produced parts are ready, just when will the NOVA parts show up?

Al, top notch as we can all see. Question, are you going to be using General size bearings for this line of motors?

Yes, the A/A 21 Pro will use the same bearings as do the MAC 21 and CMB.

When they are completed and ready to run, the A/A 21 Pro will drop right in where you had a MAC 21 or a CMB 21. Except for the piston/sleeve and crankshafts, all parts are made in the USA. These will come as kits for you to finish.
