318 MAX fuel economy builds?
I found one of those with 318-sized ports. I was very pleased with it.
When I did the 2-4 swap on my first Magnum, the intake was $20. Glass beaded it at work, a rattle can of Chrysler blue for IIRC, under $7, good cheap performance and good looks, can’t beat it.
I have no experience with those, but the idea seems really good for an engine, set up to run on the lean side.
I had really good success with the hi-amperage Square-top Accell Super Coil, and it has taken my Barracuda to around 135,000 miles, with nary a complaint. About a 100,000 of those were with the 367, from which I just took the plugs out last month, that were installed in 1999; I kid you not.
The one and only MSD that has worked for me was a gem. It added about a 1-1/2 to 2 mpg’s on the Hwy. It was easy to hook up. I did tweak the carb (Federal-Mougal 625 AFB ) a good bit over and over until I was happy with it. The car was heavy-ish at 3700+ dry. I was a skinny fella back the at time at around 160/170 max.
I’d pack the car up and travel to Georgia or the Virginia off of Long Island NY. The best I did was running it near empty to the tune of 400 miles per 20 gallon tank. That was really pushing it. The car was listed as having a 20 gallon tank.
I never tried headers back then. NY State demanded cats on the car, so off of the exhaust manifolds was a dual 2-1/4 H piped exhaust with twin high flow cats & simple turbo mufflers from Walker IIRC. A 2.76 rear gear rolling 235/60/15’s and keeping I-95 speeds down to 70 or less was key. Through the night traveling makes that very easy and being young, non-stop unless the car was hungry.
Once I got the tune nicely in, that was the last set of plugs I had until the car left me. I had gotten 3 years out of the plugs when I last checked them, they were looking good, so I threw them back in and off I went.
I don’t want to say get a MSD, since they were most crap boxes for me but I will say get a multi spark ignition onto your car and then re-jet the carb if need be. I ran mine pretty lean.
Missing a couple of more tricks, I would have liked to have tried them out. Headers with a larger exhaust and a TQ are among them. But a solid 20 out of a 360 in a loaded ‘79 B body worked OK for me back then.
LMAO - FWIW - a knthe. 93 octane was a grossly overpriced amount of $1.50 and I was outraged at that!
LOL!
