from what i've been told in my "hello" thread, we've got some automotive geniuses here. now i am just curious, how much time/money VERY roughly do you think it would cost to change an engine... oh... say a '78 360 c.i. 2 barrel (w/t cherokee, in case that is impotant) to fuel injection? also, quality is an issue in cost, so say the most cost-efficient. why would you want to do it? for better performance and milage, right? anyone done it? thanks for answering my curiousity and scheming.

It's going to cost you $1100, no matter how you slice it. $800 if you get EVERYTHING from E-Bay.

The less money you spend, the more time you'll need to get it up and running, so figure that in if time is valuable.

It cost me about 400 bucks or less, using a free 4bbl manifold and a 2bbl Holley Projection kit I got from someone here on the board for 250 bucks. I got some parts to refresh the throttle body and a new fuel pump, and I was in business. It really perked up the old girl smile.gif I had it up and running in a day, then took a while to fine tune it.

A Throttle body unit will be the least expensive. You can get away with the 2bbl version of the projection used by holley but it still requires that it is mounted onto a 4bbl flange. I was planning on getting a 2bbl t 4bbl adapter place (any reason why this wont work gang?).

It is not too difficult. You will get better gas milage and will not have to worry about the truck stalling on hills.

Just remember bacon, your in california. Watch out for the smog nazis!!!! Custom EFIs seems to be the best bet, but is not smog legal. Hes to small of a company to go through all the CARB testing and approval stuff.

Unless you have a way around the smog checks, make sure what ever you do is smog legal, or youll be changing it out to your stock carb every 2 years!
