based on info in the OLD MANUAL that I have,

3633S = auto trans 401" calls for

Prim. Jet @ .092" (pn.-120-256)
Sec. Jet @ .082" (pn.-120-158)

step-up rod = pn.- 16-219
1 step lean = pn.- 16-252U

accell pump shooters @ .028"

Hope this helps!!

Larry,
thanks for the info. The carb. The jets/rods. That are in it are considerably
leaner (primary) causing the surging going down the highway. Question: Would you also have the venturi/booster spec's for this carb? Just want to make sure everything else is ok, also the factory cfm rating.

Thanks for your time and info.....norm
