Here is my old A12 that I sold for $3500.00 freshly rebuilt, most the specs are in the description. I sold it for peanuts to who I thought was going to be a long term good friend, certainly wasn't the case.

Sunny Truck worked A12

At her most reliable best she made 106hp at the wheels in full race head outfit and big induction. Street I ran her with tighter induction and smaller port head to get some low rpm power. Great motor, the owner destroyed it in six months, brought it back to me to inspect. A sad day indeed.
