"The BON mentions a gain of 40 horses with the F4b setup, so maybe
approx. 200 at the flywheel translates to about 135 at the rear wheels?"
A Tiger email lister said he was able to get 278HP out of a 260 by using 4bl carb, high rise manifold and street roller cam ( also roller rockers) with screw in studs (revs up to 7000rpm). By the way, Edelbrock electric choke carb and F4B manifold. He may have been able to get 10 – 15 HP more if he used a current Edelbrock high rise like the RPM manifold.
I recently built a 260 with street roller cam, roller rockers, roller timing chain, F4B, Edelbrock carb, and heads with porting and slightly larger than stock valves. My goal is 275 – 280HP.
