Late 90’s chevy 4.3/5.0/5.7 brackets and pulleys, 302 ford crank pulley

Is it a bolt on and go or modifications needed?

I've never used a pressure gauge with a Q-Jet. All of them ran just fine with whatever the pump was putting out.

Now the Edelbrock I have only likes about 5.5 psi so I use a regulator and gauge on that.

I was going to ask about that bracket setup also, I would love to have a serpentine setup on the 455

OK OK OK

New question

need a port for distributor advance and heat a/c box controls

That front passenger side port is for the distributor, there should be a threaded fitting/larger nipple at the rear base to work for the heater vac source.

I was designing adapter bracket to do this and another guy on real olds power had the same idea so I stoped on mine and bought a set of his. I think his name is Larry but I don’t know if he still makes them or not and there way nicer than the ones I was doing myself If people on here are interested in sets we may be able to track him down on Facebook the crank pulley was the most modded thing I welded the center up turned it out to fit the olds balancer and redrilled the bolt holes

Nope nothing in the back beside what you see in the pic I posted.

The base on this carb doesn't have the threaded fitting for the brakes.

So I had to use the manifold port behind the carb for the brakes and now need a manifold vacuum off the carb for the heater/ac

And I will use the one I marked for the distributor.

Odd, even that mutt Q-Jet I picked up this summer has that rear port. Worse case get a two nipple threaded port or two port brass fitting to replace the one on the intake. Older Chevelles had ine with a threaded port for the brake booster & a hose nipple for the heater-A/C vac line.
