DUI dizzy on 258...worth it?

[willness33]

Who's got one and was it worth the $? I'm considering my next mechanical upgrade to milk a seat of the pants 10 more horse pressures out of the old 258. I know 4.0 heads flow better and all that jazz and its about the best thing for the 4.2. I'm almost happy with what I have. It's all stock except for a weber 38 and a header. There are cheaper HEI distributors on the market but I've read that the DUI has a better suited advance curve for the old jeep. What say ye?

Put one on my ‘85 CJ7 years ago. Called and talked to them. They asked everything about the motor, exhaust, trans (auto vs. manual), gears, tire size, ETC. they mailed it out. It was a very noticeable difference. My .02 is it was absolute worth it.
