Thank you for your comments Ernesto, I include scans of Carl Dodge's barstock engine that was used to win the 1990 World Champs at 302 kph. You will notice the way the transfers are swept back to accelerate the gasses into the cylinder. One Exhaust, two Transfer and two Boost ports, ABC with rear disc induction.
I agree with you about the need to test these old engines like the Dooling 61, G24 etc. I am just begining to make a TestBench that will record Torque and RPM as there is a need to try some of these things out. I will let you know how things go later. I could send you some bits so you can make yours ( Gratis ) later if all goes well. Do you have equipment and machining skills or someone who has?
Would like to also know how the original OPS 60 with ring compared to the same engine with ABC. David Leigh ( the boat modeller ) used the original OPS 60 but with Redhead Piston and Liner to do 299 on 28 thou monoline in 1974 here in Adelaide ( 10*10 prop on 3:1 fuel with full length tuned pipe on suction ).
Greetings to ALL from sunny Adelaide, South Australia.

Hi David,the Dodge's engine is very interesting, I had never seen this sort of transfers. It seems modified Schnuerle, with two Boost.
I do have some equipment, I'd like a TestBench, unfortunately I don't have milling machine, but maybe a friend can help me. Many thanks.
All the best from Sicily, South Italy!
