... I would say to have you car scanned to see if its going into closed loop.. If it's not going into closed loop that could cause the rotten gas mileage..WW

not that I am skeptical, well, okay, I am. My LT4 has a DRM 480 383 stroker, 480hp/500ft lbs torque, and maybe once or twice EVER have I gotten 20mpg out on the open road, and then only because I was driving it nicely.

and you claim 26mpg highway????? Seriously??, gotta know whaat you are doing that I am not.

...My engine was built to be a mild 383 , everything in it is conservative, that's the difference and that's why I get 26 mpg highway...

There is an eliminator kit you can buy that allows removal of the pump while using of the original belt. Once the pump is gone you can remove the rest of the system along with the piping that goes into your exhaust manifolds and warps around the front of the engine. Then doing a simple TB by pass of the water inlet and capping it off, the front and side of your engine are much cleaner and easier to work on.

yepper, I see the differences now. had just read the "383" part. with the manual trans the gearing is certainly much different.

well, I hope you have as much fun with yours as I do with mine. no, I never thought the hp was free to operate, I did want to compare notes with you though.

good luck, see you around the campus

I would also check out the O2 sensors while I was working on it; once those loose functionality fuel usage usually goes up.

Have you checked that the cats are not plugged up, that will kill the gas mileage and power.

No removal of pump dose not throw a code.
