My other thread was getting long so I will start a new one with the showing of the final product

all that is really left is to just load the tuning software onto my laptop and set the egr so that it will never come on. Currently it has a slight high idle, at about 900rpm. Im going to check for vacuum leaks as that can cause it to want to idle high.

If anyone is interested and as time allows I will post a list of everthing I used.

I think that we would all be interested. This is bringing the faithful 235 into the modern era.

I highly doubt that a book about it would be a best seller, but a Tech Tip on the Stovebolt pages would be well read. I'd appreciate you taking the time to write one as I'd like to do it to my '54 GMC when I get to the engine.

I would happily write up a tech tip for the stovebolt page, what do I have to do?

OK at the moment I'm working on a rough draft for the tbi conversion tech tip. During the process I took lots and lots of pictures and will have links to them in as many places as I can.

Nice demo Chris - thanks - what you're doing is really interesting to me and probably many others. It's a lot of extra work for you but a flight plan with pictures on that kind of a 235 mod would really help some of us get the most out of these great old in-lines. BTW - I really liked what was coming out of that muffler - looked pretty clean - Dale

Nice.. Love the exhaust, You'll get the same thing I got with my flowmasters. Pull into a cruise or show, pop the hood and guys will be saying "wow that's a Six?" Great video look forward to the tech tip.

Thanks guys



I worked on it a bit more today. Working out the bugs that come with doing something like this.

I believe its getting a bit more fuel than needed. It starts up nice, runs nice, revs nice but when I let it idle for a long period it starts to struggle. Nice thing about fuel injection is that it won't let the engine die. I took the air cleaner off and from the top you can watch the idle air control valve (IAC) coming to save the day. When the engine starts to see it struggle, it opens up the IAC and the rpms pick back up, then repeats and it continues to do this unitl I shut it off or rev it. Revs fine even when its doing this. Took the spark plugs out and they seem a bit wet, not horribly, but wet. The spark plugs are black, mostly because of the 4bbl. This week I'm going back to the u-pull-it yard and will pickup a 2.8L injector unit to see if it corrects the problem.

Also have to get a can of starter fluid to see if there are any vacuum leaks around the adapter plate I made to mount the TBI unit.
