Jr just bought this '74 Jeep. Has a 304 and a 3speed tranny with a PTO and Ramsey's winch running off the PTO.
Not sure yet what tranny is in it or the axle ratio.
Has a gas tank in the rear and a tank under the drivers seat w/a valve to switch tanks (dual tanks).
Wow-Thanks. I'l have to Google and find this out. I think he would be better off w/disc's in the front instead of the 11" drums but keeping the drums so we have original parts.

The stock big drums work very well as long as they are in good shape and adjusted properly. A lot of people these days have never driven a vehicle with manual brakes though and don't realize you need to pump them, or how to modulate the pedal to keep them from locking up ( old school ABS). They suck if they get wet, though! But the drums can be drilled which helps a lot with the wet braking issue.
Thanks guys. Ya I have manual brakes on my '84/'86 and I like them, especially when you are on a slope and can't get the motor started etc-that is what I like about them.
I'll have to find a good write up for the drum drilling/how to as we will not get to the conversion right away.
Question, do you think (just opinion here) it would be best to turn the drums BEFORE you drill or ?
We really don't need to go disc yet (no mud out in the desert) but I would like to make it as safe for my boy's first Jeep (in case he moves back to Fla/swamp) if you know what I mean.
Seems like Jr's '74 came w/cruise control, not sure.
Also a pic of the engine bay w/all the smog stuff on it and the gas by-pass valve to switch tanks.
Rat nest
Gas by-pass valve to switch tanks. Not sure which way is which.
Looks like Jr. has an awesome Jeep! I never knew they came with dual tanks! I have heard that drums are just as good as disc. I swapped mine because I never could keep them adjusted right when Iwas younger. Probably didn't know what I was doing! Always made for an exciting stop! I can't wait too see what you two do with this thing!

Dual tanks weren't a factory option. A previous owner has just added a 55-70 under seat tank as a secondary tank. Pretty easy to do using factory parts.
More of a resto-mod than a pure restoration. Upgraded a few things in the interest of safety and reliability. Like power steering, power brakes, front disks (complete knuckle-out swap from a 78 CJ5), 3 point seat belts, etc.
Jr's Jeep (304) has points for the dizzy and I'm going to mention to him about changing it out for electronic (although I wouldn't mind it).
Without going to the HEI, will a newer, say 1980 dizzy work and will he have to take the cam gear off the old one (I've heard horror stories about the dizzy gear eating up the cam gear on some HEi's-that is why I would recommend to him just get a factory replacement and do the cap etc upgrade)
Question, he wants to go full width axles and we are looking at two Waggys for the price of $400.00 complete (except one is missing just the motor, the other has a 360).
Is there a kit for this that will work on his '74 CJ5.
OK, did a compression test (WOT) on Jr's 304 and we need some help here w/the results.
Results Drivers Side Front to Back (no smoke from this side):
122-clean plug
122-clean plug
125-plug a little fouled
105-clean plug
Results Passenger Side front to Back (big time smoke from this side):
116-clean plug
125-clean plug
115-plug fouled big time
125-clean plug
Seems like the passenger side cylinder is the one that's doing all the smoking.
He is running a Autolite 65 plug and we want to try a hotter plug but not sure what number to run. I called O'Reilly and the guy suggested a Autolite 866.
We would like to try the hotter plug so he can drive it to the pressure wash station before we do a valve job.
Wet test on cylinders in question. All plugs in on both tests except the cylinder in question. WOT.
Results Drivers Side Front to Back (no smoke from this side):
122-clean plug
122-clean plug
125-plug a little fouled
105-clean plug - Added some WD-40 and the cylinder went up to 110lbs.
Results Passenger Side front to Back (big time smoke from this side):

115-plug fouled big time - Added some WD-40 and the cylinder went up to 124lbs.
125-clean plug
I let it idle for a while to maybe burn the oil oil out of the cylinder (maybe 10min). Then I drove it around the 3 acres and it kept smoking.
I then stopped and help the throttle @ about 1500 rpm and punched it a few times. Big time smoke and also when I took my foor off the accellerator pedal I did see some smoke (not much but visible in the daylight) coming out.
Here are the new compression numbers with ALL the plugs out/WOT/engine cold.
NEW NUMBERS
Drivers side front to rear:
118
125
126
105
Question, if he pulls a 360 that has a auto behind it, can he take the pressure plate (where the clutch rides/motor turns the tranny) off the 304 and bolt it to the 360 or does he have to get one for a 360?
Question, will the same work for a 401?
Also, will his bell housing will bolt up to the 360 and the 401?
Amc Motors are externally balanced so you will need to find a pressure plate for a 360. Externally all of the amc blocks are the same so the bell housing is interchangeable from the 304 up to the 401.
