This a Rucker overhead valve conversion with two Stromberg 97's

Nice. Route 66 is still open in places and is a nice diversion from Highway 40.

What have you done to the bottom end to support the head and carbs?

I've heard this has been approved.

MAFCA 2027 National Tour – Proposed – Route 66 West to East and East to West - Temecula Valley A’s (California)


When I send in a photo for MAFCA's A of the Day I include the Route 66 logo if it's along that historic highway.

Is Rucker a new product?

History lesson for today,

Rucker's were made when the Model A was new. They are somewhat rare now. They were similar to several OHV heads of the day, like the Cragar heads they could use stock A manifolds or aftermarket manifolds to suit. Miller, later made by Cragar, advertised that their head would double the A horsepower when a slightly larger carb was used.

Cragar's, and likely others, used 6 cyl. Buick rocker arms, 1.25:1 ratio.

There were at least 50 OHV conversions made for the A/B engines back in te day, and some are still being made today. The ones being made today are much improved, I've seen 225 HP on the dyno, and that engine was built as a touring engine, not a racer!
