OK. I can't afford a new 350 for my Suburban, so I need some honest info on what would make my tired old 283 get decent gas mileage, and power. It came from a 63 Biscayne, with a Powerglide originally, and I had it supposedly rebuilt in 1996. Now it won't get out of it's own way, and the 6 mpg doesn't work. Would a cam and lifter change help? Also, my carb is currently a rebuilt Carter 500CFM. I was going to sell the 283 and P/G together as they were a matched set, but since I live in an apartment, I can't do an engine swap there. I'm on an extremely limited budget, so I may have to get the parts, then have someone install them. Any help would be GREATLY appreciated. I have asked about this before on here, but everyone suggested a 350. Believe me, I appreciate all the replies, but things have become worse now , financially, so looking to rebuild the engine on a budget.Thanks everyone
Not engine related but have you considered changing the differential ratio your rear axle?
what ratio do you recommend? Right now I'm driving about 20 miles one way on the highway, and about 2 miles of city streets.
