Question on throttle stroke

[AnthonyG]

Reporting back: Steep angle from the accelerator throttle lever to carb was an issue and I went to a cable. However it turned out the throttle lever mounted on the firewall was cracked causing a lot of flex reducing stroke significantly. Found good replacement lever and installed. That in combination with throttle cable replacing the hard linkage & mounted on carb base to have a more level operating plain corrected the problem.
Thx for the help,

I modified a ss braided throttle cable to snap on the ball on top of firewall pivot and used one of the rear carb mounting bolts to secure cable on level pull plain approx 8 " behind butterfly throttle shaft. Seems to open all the way now. Will test today. As Mart and V8Coopman indicated it most likely was the steep angle due to hi- rise messing up the geometry. PS V8Coopman, I like the "goofy" hi-rise setup, eyes of the beholder you know and a lot more torque. also gives me a good platform for running multiple carb setup which would normally have interference with alternator setup.I do thank you for picking up the geometry issue, it was a good call
Thx to all for the good advise and ideas.

If you read JWL's book, his dyno tests show that the riser for a 4 bbl carb actually hurts performance.

It may not increase HP but definitely feels like the torque curve changes at low end and pulls harder. Never race or beat the car. Just an occasional punch off the line. Mainly for the looks. I have just switched over to another " Goofey Hi-rise Tri-power setup" . Again "eyes of the beholder" I like the look.
