Just what I needed.

June 04, 2012
I tried to create an adapter for my Mopar 360 stock intake that had a Q-jet on it and I have a manual choke Holley 4160.I built the 360 bonestock.It came frome an 86 pickup with a 4 speed.I've built a 26 Modified around it.The home made-wooden-adapter I carved,leaked and had a vacume leak.I have the engine running fine now.The adapter works like a spacer-insulator.PERFECT.Now I can work on the other things so I can drive it.
Pros:
  • Easy To Install
  • Lightweight
  • Durable
  • Improves Engine Efficiency
  • Increases Power
  • This is just right
Yes, I recommend this product.

Great item for the price

May 18, 2014
I had an intake that was not a dual bolt pattern (Holley only). Wanted to bolt on a Q-Jet with the least expense possible, and this item fit the bill perfectly. There were two reasons that I did not give this item five stars: (1) You need to re-use your Q-Jet bolts with this, and I did not have those, so I had to buy. The kit comes with short studs; and (2) there were quite a few molding/flash lines on the adapter that I need to de-burr to eliminate stress points and sharp edges. Other than that, if you need a cheap way to convert from square to spreadbore, this is a good product to accomplish that.
Pros:
  • good value for price
  • short studs included
  • Gaskets Included
Cons:
  • no q-jet bolts included
  • sharp edges
Yes, I recommend this product.

Adapter number 1351932 will allow the installer to put a Holley, Demon, or Edelbrock carburetor on the Chevy intake originally having a Quadrajet carburetor. The side of the intake with the Quadrajet configuration goes down on the intake manifold leaving the square pattern base for the Holley or Edelbrock carburetors.
