I\ve had alot of trobule osting this, so I left some of the comments out. Thr adapter is bolted to the guide, In JWL's verson he made the unit in one piece as you can see in his book. This bowl fits under a 1.72 chevy valve the stock bowl is bored with a 60 deg mill and the guide and adapter is inserted into the valve bowl which registers' on a locating slot in the block. Once installed it"s shaped tp provide an easy escape for the incoming AF/ I got this idea from a guy that ran a Bivlle but he brazed a piece of material th the underside of the valne in the bowl back in the 70's probably one of Petes friends, Making the port liniar is John;s idea, makes sens to remove as much turbulance to air flow as possable. I'll probly never run this at 90 it just another idea that might help thise tha followl
Gramps
PS Wait till you see the intake manufold?????
