TBI 454 Build - 50 State Legal

[eldogg]

Mine is .030 over w/flat top pistons (70 LS6 style), balanced, Smallest Summit cam, Comp roller tip rockers, Edelbrock TBI intake, Edelbrock headers, TBI chip, Upgraded fuel pump and regulator spring, Single 3" exhaust w/ largest Magnaflow muffler. I get 11-12 mpg in town and 7-8 mpg hwy. TH400 4:10 235/85/16. It will run on 87 but it likes 89 a whole lot better. I will give the pepsi challenge to any stock diesel to about 70mph. If you have any questions about my combo PM me. There is some pics of it on here. http://queencityspeed.blogspot.com/2...lug-wires.html

Holy cow that's horrible. With a TBI even......

Find someone to tweak the tables on that chip some more.

My 640 HP 454 chevelle with 4.10's and 400 turbo does better on gas than that with a big fat 950 double pumper holley.

Wish I still had my chip burning equipment here but I sold everything when the market slowed and OBDII was introduced.
