In a former combo in my 69 nova I got close to 20 mpg with a 2.56 gear and th350. The motor had maybe 9 to 1 compression 76cc smog heads with cheap flat tops. It also had a 268 high energy comp cam 218@.050 454 lift for both intake and exhaust. on top was a Performer Rpm with a 625 Carter Afb. It ran 15 flat @ something like 88mph(this was going through traps in 2nd gear) It was by no means quick but the mileage was good for long road trips. This was on a 350 bored .030. hope this helpsLast edited by average joe; 02-15-2009 at 10:22 AM.
