I'm willing to argue the point. it's ridiculous to pull the race-car thousands of miles and get 1/2 a lap in a the cable breaks! I haven't talked to anyone who has an idea how to fix this problem. Apparently Gulf gave up on the cable also.

i think you should try and convince them you should use a 600 CFM holley carb with the center pivot float bowls.

i think it might have been a 370 inch motor and i don't think the FI even with dual air meters had enought air for that size engine.

It was definitely running out of air or cam

Quite a few drag racers in the late '60s early '70s experimented with modifying FI units because of their desirable "ram" effect. One that I raced with, Ralph Ridgeway, was one of the more successful to do so. He developed the "Ridge Runner" which was made in Rockville CT.

Back in the early 60's there was a speed shop "Dyno Tune By Deb" in Springfield, MA that modified a Corvette F I manifold to use with a carburator and got very good results. There was big article in the local paper about it.

Tom. Do you know the source of the drawing (thumbtack)that you included. Do you know the intent of this modification? Jerry
