TH700R4 linkage geometry for holley base - The 1947 - Present Chevrolet & GMC Truck Message Board Network

38chevyhotrod · 04-22-2009, 03:46 PM

I put a 700r4 in my suburban and hooked it up to a edelbrock carb, i have bought a kit for that at bowtie.
Now I want to replace the edelbrock carb with only a holley baseplate, because I am going to run only on LPG.

The problem is that i need a new bracket to make sure the geometry is corrected for the th700 tv cable.

I have found two different types of measurements.
If i use this http://www.purplesagetradingpost.com...o/700R4p7.html Than i come up with a different hookup point than if i use the standard ones like this http://holley.com/20-121.asp

Does someone know what the correct measurement is for the tv cable?
I have seen a post somewhere from someone that adjusted the standard holley bracket because it did not work correct.

there isn't a set measurement for the TV cable, that's why it is adjustable. And for me to switch to my edelbrock carb from a holley I had to use the edelbrock transmission hook up.

are you using a stock TV cable?
I have a LOKAR TV cable in my Blazer, and am using that cable with a Lokar bracket that attaches to the base of my holley carb. This is the 3rd or 4th one of these that I have used and they work great. Plenty of adjust ability, and the cable is level from the bracket to the carb.
