Ge the one 32/36 DGEV-IC this is the one with the cut off soliniod so you dont have run on. I believe your stock carb will have this. Alot of webers on the market will not have this weber cutoff option But hese are expensive new. Most on the market are the man DGV with the small idle jet holder and cannot be made to hold the cut off soliniod. I notice the 32/36DGAV can be made to the soliniod cuttoff option. It will have a Bigger idle jet holder(brass screw head).
Oh by the way your not going to get seat of the pants power.
Webers are just a Ezer carb to maintain with a little enhancment.
If buying a carb used you still need the adpater plate. I ported mine out to match the weber so there was no sharp edges to trip the airflow.
it cost alot of money to build a small motor,But in the long run it will be worth it. Than nickle an dime here and there.
If there is a conversion from points do it. Pertronix has the 74-75 LUV points conversion. But will not fit the later distributers
Im not a fan of the mallory UNILITES but hook them up correctly.There might be a unilite conversion. I would not pay 200 for the whole distributor(not worth it)
Also is the Crane Cams(ex Allison )XR700 conversion. Alot of people like them but has a box to place somewhere.

As for headers I dont really think you need them unless you have dual carbs(like me). Just up size the pipe abit and run a Dynomax Superturbo(they have all sizes) its not to loud. If want more quiet get a clifornia Turbo (2 or 3 chamber turbo).
