Well, I'm looking at 1998 Chevy 2500 with the 7.4liter 454 V-8 ext cab shortbox right now and I'm just a little weary about how the fuel economy will compare to my 92 with the 350.
This particular 454 has been completely stripped down and rebuilt, bored .30 over, performance Cam, headers, 3" dual exhaust into flowmaster 40's, Stock 245 85 16 tires, 3:73 gearing, etc. The guy says that he gets 12-14mpgs combining his city driving with his 5th wheel pulling.
Otherwise, it's a rust free New Mexico truck up here in Michigan with 156,000 miles on it. He want's $4500 for it
Thoughts, input, concerns, questions??? Shoot
