I'm running a Thermoquad intake with a square based Holley. I am using a square bore spacer about 1/2 inch thick and it works perfect. I also have a small block Thermoquad intake with the small intake runners. They were used on 318 and 360 engines around 80-83 and possibly later. I am planning on using it for a 318 in a Dart.
Good to know, thanks.
Any reason you cant just take a die grinder to the offending metal?
I'm afraid of sparks.
Seriously, that's not a bad idea & I will take a look at the intake this weekend.
Just buy the adapter and be done if you want to go 4bbl route.
You know I had 3 or 4 of these adapters in a box years ago that came wirh a variety of cars & parts over the years. I put them out at a swap meet & gave one to a friend & wish I had kept one to try out to make sure clearance would be okay.
