If he still does it anyway.

Adapting a Edelbrock to a pre 73 Chevy pickup isn't the easiest thing.

Throttle and kickdown cables are funky on them.






Yes, if the trans is Th400, that tv cable....

The TH 400 uses an electric kickdown switch, there is no tv (throttle vavle) cable... The TH 350 uses a kickdown cable (kicks trans into a lower gear for better acceleration) operated by the carb linkage... There is no tv cable on it either... TV (throttle vavle) cables were used on TH700 4r's and TH200 r4's in the 80's to control hydraulic pressure in the transmission...



I was fishing for a reaction from JC, he questioned of TH400 would be in there behind a sbc in a c10 so that sort of dead ended on me. No cable on th400.

You should come and fix one of my aluminum powerglides. It shifts super prematurely in drive and will not kick down. Does fine if shifted manually. I think it's a governor issue, thoughts?

Only powerglide i've ever messed with is the cast iron version in my 55 Bel-Air... Had my trans guy rebuild it and he removed the TV linkage bracket from the side of the trans (which was unnecessary and lost the factory adjustment which is critical to proper function)... Wound up fabricating my own tv bracket adjustment tooling (from photos and specs in my 55 chev shop manual)... My brother gave me a 63 Chevy II when i was 13 that had an aluminum glide... I put an engine in it (6 popper) and drove it around in his salvage yard... Never messed with the trans... I would suggest getting an old shop manual (or chilton) read the trouble shooting section and go from there...
