Thinking about a Howell

Hey guys, I'm thinking about a Howell for my J10. I'm getting tired of the constant fiddling with the stepper motor carb. It runs fine but it's always needy. The only reason I still have it is because its what came with the truck from the factory. I have a Mopar setup on my Scrambler and love it, but I sold all the original smog equipment and regret not keeping the factory stuff just in case. What do you think, keep the carb for purity or go EFi for driveability.

I love mine already. Cold start and idle are so much better. Haven't been able to drive it much yet to check MPG but gotta figure it's going to be quite an improvement.
Doing a build thread on it, see my sig, if you are wondering how involved it is.

Do it. It makes smog check MUCH easier. Read Mystic Robs install and it will really help out, too.

Thanks for the advice guys. This is the last piece to make this a truly reliable daily. I'll keep all the original smog equipment just in case in the future someone wants it all original. I should have kept smog from my scrambler when I did the Hesco. I never thought that stuff would be valuable. Live and learn.

Honestly, at this point, I would chuck it anyway. A complete Howell kit is $1400 and removes a ton of vacuum line spaghetti and the smog pump. So when most people start having problems and failing smog, they just go to a Howell kit or engine swap. It's not worth the hassle to mess with the stock stuff in CA, especially when many folks are paying a shop to do the work.

Really, the nice thing about the Howell kit (even more than it being EFI) is getting rid of the tons vacuum lines/leaks. I probably have, collectively, 60 man hours of work fighting with vacuum lines and EVAP leaks. You will still have EVAP but simplifying your vacuum system is sooooo nice.

In my time on this forum, I have probably seen 3 smog pumps switch hands, total, in the classifieds. Even when they do switch hands, they are dirt cheap. Not worth holding on to IMHO. Hold on to all your smog stuff until you pass with the Howell kit for the first time, then chuck it. It's really only some vacuum lines, a carb, a smog pump, and the lines that go into your manifolds (which most folks leave but some remove). Sometimes the Carb will sell for a little money but the smog pump and it's lines, meh.

You will have very few "regrets" converting to EFI!
If you are pc literate and junkyard resourceful?
You can roll your own "howell" system.
It's all standard GM parts, and isn't difficult.
