Re: Muncie 4spd to NP440 conversion 66 GMG 3/4 ton
I need something usable and reasonable on gas . Originally I had the 305E in this truck circa 1980 and it never missed a gas station altho it was a great running and fun to drive .
At least GMC offered the 292 and so I put that in , in 1987 .
Now that Holley has an new EFI Sniper it looks like with this tranny its gonna be a win win .The 292 is a nice motor and mine runs great but it will cost the same to fix the head gasket small oil leak , replace the header , switch to 4 bl carb , cam etc . than to pop in a 350 .Probly get better milage .
