Combo Advice 340
Cam? Custom grind for a F.A.S.T. class racing or something like it. Stick with the roller and call Comp Cams or Crane cams for what you want.
AVS Carb;
AVS parts are the same as a AFB. If it is an O.E. AVS, then you'll need to flatten or purchase new spring/piston/rod covers that are flat. The AVS rods are a tad longer than AFB rods, but will otherwise swap.
Use of AFB rods in the AVS with the stock covers will allow the rod to come out of the jet and run the engine crazy rich and also may not go back into the jet and jam up.
All parts should be easy to get from Edelbrock.
