    I have an 85 Jimmy. It has currently has a 305. I want to change it to either a 350, 383 or 400. My question is what type of fuel injection is better and which one would be easier to swap to. What would I need to do with the tranny. It is a th-700. Thanks!

    You'll here lots of different opinions. I think that a TBI system from a stock 87-91 350 CI will be fairly cheap (300-500) and will control your trany lockup.

    Frank,
    What kind of response did you get on a "EFI forum"? I think it would help people out a lot. BTW I want to do a TPI next, maybe on our 85 K5.

    Mark, what I proposed in the 'Feedback' forum was a tech section about FI - links to ALL kinds of websites (I have about 25 good ones), basic info (like what type of pump is needed, etc.)...........left it up on the board for 8 days, got NO responses, said screw it and deleted it. Guess I should have put it on this board, but felt I was following the pseudo rules. I still think it is a very good idea, and with as many posts as there are about FI of all types it would be useful. Whether is is in a forum or just a tech section (article or whatever) is up in the air..............tho it would be nice to continually be able to add info/ideas/facts/findings, so maybe a forum.

    Whatcha think?

    I think its a great idea. I suggest emailing Steve. I like the idea of going to a certain location that interested people will answer question about EFI. A tech section or article, or some sort of FAQ is also a great idea. I would help if I could contribute anything. I have some Wiring diagnostic and wiring diagrams, and several books and factory manuals. Maybe we could list which people had what manuals for reference and would help people out? There is a lot of expertise on this site (I'm not including me as expertise).

    Only thing I would suggest is to actually have the info located on Steve's server. I know he runs into space issues, and *likely* those other sites aren't going anywhere, but its nice not to have to wade through a bunch of impertinent info, and keep on top of links going bad.

    Its been my experience that most companies and individuals don't mind if you use their info, as long as they are given credit, or a link to their page is maintained.

    Besides, there can be a lot of specific truck info, like wiring through the bulkhead connector, and working with existing wiring, that other places probably don't have, or if they do, its hard to find.

    Why insist on counting when the ring gear has the tooth counts stamped in?
