I am building (another) race Amazon - this time for late '50's racing with the B16 engine and front drum brakes. I have previously built a B18 for tarmac rallying (see Youtube 'volvo' & 'targa')
Has anyone had experience with modifying the B16 engine for racing - HS6 carbs?, big valves, head work? crank?, cam specs. The Group Na class of racing allows boring to 1642cc. Any information, advice welcome.

 

Sounds like you can answer my question, or maybe point me in the right direction. I bought a MG TF that has a B16 w/ H6 transmission. I’m looking to find the year of the engine by serial number. Any help appreciated

 

Ken Rudd (UK) made a business of modifying Volvo's "back in the day" You might search and try to find his specs. Bigger carbs were definitely part of the package. The package had enough go power that the drum brakes were marginal at best.
