10ish
11-14 depending on how your drive it.
About 10 MPG. if your lucky.
I have an 86 with a 4.3 and it regularly gets 21 - 23 miles per gallon combined (city/hwy). I can't answer for the 5.0
i need to no the color codes to a 1976 el camino ignition
and would i have to buy el camino parts for Chevy 1500 tranny or would i buy Chevy 1500 parts for the tranny?
That would depend on what year, what engine, and what transmission, it has. You listed none of this necessary information for a correct estimate. And mileage is just that, and estimate. How you drive and the condition of the vehicle are also critical to your mileage.
Your 1992 Chevy Lumina will run with a bad 02 sensor. The engine will seem to be sluggish and the fuel mileage will go down.
No, this would not be a direct bolt in.
A new engine is tighter and that causes more friction. If the engine had to be bored / over sized for new and bigger pistons then that will cause poor fuel mileage too. The gas mileage might be down a little at first, but once the engine gets broken in there shouldn't be much difference unless the cam or compression ratio has been changed.
18 City stop and go traffic and with A/C. 22 Straight highway driving.
What would cause the engine not to restart when hot Chevy Trailblazer 2007?
Any hood from a 1978-83 Chevy Malibu or 1978-87 El Camino or GMC Caballero would work.
