I had a 73-1/2 Javelin, built in April. Some have pointed out early 73 builds had the darker engine blue. Mine was the lighter blue. I get the names confused, so I won't try to state one or the other. There are some engine restoration threads, that cover how AMC painted their engines. The only big changes between.

Re: 258 AMC Jeep crankshaft question. by wyrmrider » Thu Mar 20, 2014 4:42 am. from the web. Felpro 8169PT measures 0.050" thick at the fire ring and the fire ring inside diameter is 3.875", resulting in a gasket volume of 9.7 cc. I have also used a gasket from Victor which had a 0.042" thick fire ring (8.1 cc gasket volume), I add.

Jeep had some differences, over amc cars with some engine components, namely pulleys. It is possible it came from an AMC car, not a jeep. 71 Javelin SST body. 390 69 crank, 70 block & heads. NASCAR SB2 rods & pistons. 78 Jeep TH400 w/ 2.76 Low. 50/50 Ford-AMC Suspension. 79 F150 rear & 8.8 axles.

Thanks!! 360 crank is cast, and will have sharp, approximately 1/16 of an inch parting lines that have ragged edges. The 401 crank is forged, and those lines will be 1/4 inch wide or more and smooth. If someone put a 401 crank in a 360, the engine should have been balanced as 360 pistons would be lighter than 401 pistons.

The marketing angle was all about looks, and with the 4×4 feature, AMC preened about creating a new niche: the off-road sports car.

The 390 crank has enough journal DIA. to de stroke without welding. In order to do that, the journal diameter would be smaller than AMC spec. Other than AMC rods would be needed, which of course there isn't a commonly available factory 290/343 forged rod anymore anyway. Unless aftermarket forged rods were used.

I'm fairly sure fellow AMC-lovers are going to come out of the woodwork to defend the AMC V8, which came primarily in three variants: 304, 360, and 401. "Mine has driven over 200,000 miles," some will say. "This guy just doesn't know how to wrench," others will claim. "It was a torque, stout motor," many will cry.

Mandatory oil system mods. The oiling passage in all the aftermarket cams and timing gears needs to be checked. The front cam journal supplies a path for oil going to the distributor drive gear. Many times the timing gear has that groove in the wrong place or the groove extends beyond the diameter of the cam's front journal.

Feb 28, 2017. For many of you in the engine builder community, word of mouth among your customers has a large impact on your business.

Also, I was incorrect on the AMC 390/401 rods being wider than the SBC. I was thinking of the AMC 327 forged rods, which are 1.00” wide and have the same journal size as the 390/401 (327 rods are 6.375” long and are FORGED). The 390/401 rods are around 0.92” wide, while SBC are 0.94” wide.

Or a crankshaft with a scored rod journal. The 401 rod bearing journals are 2.25" OD. Like a big block Chevy. That leaves a lot of room for custom work. I will be using a 360 block bored to 4.125" for 400 Chevy pistons (w/1.425" compression height, like for a 5.7" rod 400). I will use 5.88" Chevy rods, and offset grind the 401 crankshaft to 3.8 ...

crankshaft was softer than the bearing. AMC must have been cutting back on the metallurgy in their. 360 cranks in the 80s and not suitable for standard transmissions. And this was with the tiny 1800 lb. pressure plate that came with them. I done have that problem with the 1975 401 crank with 2800. pressure plate.

Has anyone tried the AMC stroker crankshaft from K1? They also offer AMC billet H-beam rods in 6" and 6.125" for the crank. K1's online catalog doesn't list the AMC crank and the longer rods, so I called them on Friday. According to K1, the crank has a 4" stroke and 2.100" rod journals. The rods have .927 wrist pin journals.
