401 Build

Mudrat

Scared the crap outta me the first time!!! I "guessed" at the timing from TDC and as soon as I turned the key (after dumping some gas in the carb) it broke lose at a high idle - straight pipes no muflers. Now I can't get enough of it :lo1l: :lo1l: :lo1l: :lo1l: :t: Guess at some point I'll have to muffle it :smile: But HOT DAMN that was a great feeling!!! :?

One last comment. The engine now has about 200 miles on it. NO LEAKS!!! Put a new tranny seal in when the engine was out. I bet I have one of a very few Grand Wagoneers with no fluid leaks. Time for the new garage floor I have been wanting. :!:

Don, Very nice writeup on your 401 build. It's was nice to see the real results of your build (dyno data, etc.) I'm very interested in how your drivability is in the waggy and your satisfaction with your cam choice. I am building a new 401 for my CJ-8 and am considering running the cam you have. I previously have run the Edelbrock Performer 2132 and would like a little more cam w/o losing the low end grunt and throttle response. The only basic differences in my build plans are to run the stock 58 cc heads and likely run the TRW L2308 forged pistons. Your latest feedback would be appreciated. Oh yeah....how much vacuum do you have at idle? Thanks, Scott

Thanks. When I tuned the carb I had 15Hg at idle. I think it has pretty good street manners. Seat of the pants power is at least double.
