Need help with Edelbrock DP4B inatake from 1970's for 383 - the stock throttle brackets don't line up with the mounting hole in manifold, what does a finished bracket end up looking like? Did Edelbrock supply throttle brackets that did fit and require no mods to work?

Also - what is the hole in the top of the manifold for, the hole just below the water/nitroous injection threaded port, it leads a channel that flows out the bottom of the manifold. Some DP4B's didn't have this hole/channel cast into them. Thanks men!

Here is a link to more pics of hole in manifold top and channels/leading to the bottom

My stock brackets worked on mine, they are suppose to be cast like a cast iorn one so shoud;nt be a problem if you have the right brackets

back in the day i used the orignal '68 bracket when i went to the dp4b. the later 2 hole brackets may have an issue with the wider runners.

I like new good quality parts on my engine like the stuff AndyF sells

Okay great I really appreciate the info. Here is the bracket style being used and has the protrusion at tip (circled) doesn't allow the holes to line up.

Here's a similar/different B engine throttle bracket that may be a direct fit for DP4B - since it doesn't have any protrusion cast into this 'style.' What have you all done to the style (above; w/protrusion) to get it to fit?

Here are the two 'ports' in question; one under carb leading into plenum is threaded and all DP4B's I've seen have always been plugged.

The other hole below that - I've seen a golf tee plugging it in one guy's...

the lower hole connects to the heat crossover and is for a tube that would connect to the hot air choke of the older 3310 holley. with the advent of electric chokes this port isn't needed. the port up by the plenum is just vacuum take-off port. plug it if it's not needed.

Great to know this bit of info. So the coil was moved to accommodate the 3310 Holleys, too, and the choke ports. Those two hot choke holes will need plugged some way when running other carbs.

Which of the two Mopar B engine throttle brackets pictured above did you men have no install issues with? From the looks they both appear to be too thick at the mounting hole area...

Glad to update this old thread I started a few months ago. Here is the '70 B engine throttle bracket after grinding off the area (shown above) to clear the DP4B's #7 runner.

And then use Fel Pro #1214 Valley Pan with Heat Block Off Crossovers installed in the pan and your good to go
