I asked about this earlier and got some responce. Well I did something about all those oil spots I was leaving all over the place. A month ago I had the son and the young man that works with us take the engine out to replace the rear main seal. I was told that it would have the externally mounted seal. Wrong. While the engine hung on the cherry picker I noticed antifreeze weaping around the three center head bolt bosses. What's wrong with this picture? After investigating you could see cracks so I took the heads off and had them magna-fluxed. They were both cracked in the same place. Had to locate another set of heads and only one qualified out. Had to go after another set of heads and one of those qualified out. Now I have a set of heads. The crank needed polishing and new main and rod bearings. The lifters starting to pit so got a new cam and lifters. Timing chain was so stretched out that it was cutting on the windage vain on the timing chain cover; new chain and gears. Got it going a week ago and it ran great other than the vacuum advance diaphram was leaking. The diaphram was $46.00 and a rebuilt distributor was $56.00. Yep I got the distributor. It runs great and I now know what I have for an engine. One problem though; I now know how poor the gas mileage really is. 10 MPG. What can I do to improve the Mileage? Thanks guys.

Gear Up,

That's all I get with my 302 in my '59. Are you running a 2- or 4-bbl carburetor? I'm assuming (there's my first mistake!) the engine is otherwise stock? and all the recent "corrections" were made with stock parts? Udder den dat, obvious stuff like carb jets, timing, fuel pump, rear gears, tire sizes, brake allignment, etc.

Or, you can get incredible mileage like I am right now... by not driving it! Doh! NOT an option...

could change it over to EFI. Not that hard, nor expensive, and will gain about 4-5 mpg over carbureted counterpart. Also will gain performance and hp.

there are plenty of posts on this site showing how to convert to a 88 or so mustang harness.

Good luck and cheers

OK, you have my ear... Could you be more specific about the change-over, difficulty factor, and cost?

Thanks,

cost would be around 400.00 or so. You would need a complete engine harness including sensors, fuel pump (fuel injection uses much higher pressures than the stock pump), computer (try for an A9L computer,if you are running a manual trans or an A9P for auto (aod or c-series)), intake ducting, a mass air sensor, an intake manifold off a mustang/f-series truck explorer or bronco (with EFI of course) and an O2 sensor or two to weld into your exhaust system (any exhaust shop should have the O2 bungs to weld into your exhaust). A few other odds and ends like throttle/TV linkage stuff..but thats it I think.

Note the Mustang Intake faces the left (as looked at from under the hood) and has a single inlet tube as compared to the truck manifolds that go to the right and have dual hoses which will need an $80.00 "Y" adaptor to add the Mass air flow sensor.

You can find most of the parts on Ebay and if you do the research you can find step by step instructions on the install.. It really isnt hard.

I did it on a friends truck and took a weekend to do it right.Went from 11mpg with his old system to over 15 so... not bad... it will pay for itself fairly quickly.

 

Should have let you know tht this is a HO351 with a c6 tranny. Did they have EFI for the 351 in 88? I have a yard that is willing to asist in locating parts. Just need to know if it was available.
