Hi,
I am running a TCI street/strip non-lockup 700r4 behind a 383 (technically 385 @ .040” over) stroker in my 79 Monte. The TV cable is TCI aftermarket and the carb is Barry Grant sports claw (see picture). So much time has gone by since putting the car together that I can’t remember if I did anything specific to address TV cable geometry. Or if it is even correct. I remember researching it a lot and being confused about what was correct 😉
Using the “self adjusting” procedure (slide adjuster towards firewall while pressing button then rotate to WOT), I’m pretty satisfied with the part throttle shift points but experience shifts that are too late at WOT. I’d like to have it shift around 6100 RPM but if I don’t let up it will hit an HEI controlled ~6400 limit without shifting 1-2, 2-3. I don’t really count 3-4… isn’t there something about the 700r4 design that will keep it out of overdrive unless you’re around 75% throttle or less?
I’m afraid to “loosen” the cable with the adjuster and make line pressure too low/break something. Assuming correct geometry at the throttle which I would appreciate advice on - switching from the carb to a Pro Flo 4 EFI (4150 style throttle body) in the near future, not sure if I need some kind of corrector - anyone know what kind of goals to try and achieve with line pressure?
Thanks for any tips!
Adam
