Re: Thirsty 400!!!??!!
Last year ,I built a 454 for my 69-everything is new, about 8:5 compression, a xe262 cam, roller tip rockers,Edelbrock performer and a 750 Edelbrock carb,rebuilt 400 trans,swapped the rearend to 3:23 gears(speedo is still off about 15mph)and drive at "about" 60mph and I'm at 8 mpg. Its a c-20 with 2008 hd tire/wheel take-offs 245/16. I was thinkingn maybe a 600cfm carb might help with mileage but not sure. Gear vendors would help but you can buy lots of gas for $2500......any other ideas?
