: with 341:1 rear,33" tires,700r4.
: I pull in 3rd lockup 55mph and 2100 rpm.I`m going
: to swap the engine so I have two options for a high-
: torque low rpm engine,(1400-2100 rpm).
: -93 383" (new) or the -98 350 Vortec.I`m using stock
: computer,Hypertec prom, Holley 2" TBI,low torque
: Competition cam(252 dur and 409 lift)Performer manifold,
: 2,5"high flow no cat (don`t need emission on -88 modelyear
: in Sweden),98 octane unleaded.
: What engine gives me best low rpm torque and milage??
The vortec has a special intake bolt pattern. But edelbrock is coming out with fuel injection coversion for the vortec engine. What heads does the 383 have ? Also GM in working on a 383 vortec conversion for TBI trucks.
