Throttle return spring setup for Holley 4150
Wanted to see if any of you guys have any thoughts or recommendations on throttle return spring setups for a Holley 4150 carb on a big block. So many options out there. Not sure what works well particularly if you have to run a drop base air cleaner.

I just installed an Edelbrock torker 2 and 4150 on my 427. Used the throttle cable, bracket and return springs from lokar and was a direct bolt together. Only thing I had to do was use a couple of washers to size down the hole in the firewall. Return springs worked great.

basically if you replace your quadrajet with a Holley four barrel this bracket is the way to go. I believe they may also sell a kit with the spring included.
I had been fighting with mine and I didn’t want the larger lokar or other units that take up space under the cleaner and then I found this. It actually fits into notch on the throttle body. Easy peasy.

corvettemods part number 13512. It’s a repro part for all Holley carbs except the tri power.

I’ve found personally it’s a dead tossup wether you’ll receive a part ordered from the above mentioned supplier. If they are the only one listing a part, I consider it to be not available, and look for an alternative to the problem.

Summit and Jegs offer lots of options.
Id use a dual spring set up, had one slip out of its hole, sure woke me up
Most have a smaller dia spring that slips inside the larget one.

youre running an aftermarket throttle cable though correct? My suggestion is the least invasive option. If you’re using the stock throttle cable and want to switch to the 4150/4160 then this bracket is the easiest route.
