5 Deg B4 TDC. That was as delivered.
While the AMC 3.8 L inline 6 was the standard power, a 5L (304) V8 was on the options list.
The power of the engine and the maximum speed of the 1968 AMC AMX Coupe Manual are 420 hp and 189 mph (304 km/h) respectively.
.35
With the 258 ci engine, 98 HP.With the 304 ci V8 engine, 126 HP.With the 360 ci V8 engine, 129 or 138 HP.
Yes
1-1/2"
no a 258 amc and ford 302 have same bolt pattern
No, the IHC 304 and AMC 304 are two completely different animals, and as most say in the IHC cummunity, "the only similarity would be a handful of bolts". International owned their own coal mines and steel mills and casted their own engines. Though their had been an AMC engine in a Scout (258), they generally used their own engines, with another exception being the Nissan SD33(T). FYI, somewhat on-topic; It has also been said that you can find some IH casting in MOPAR heads from the Vietnam era, where IHC may have helped MOPAR along during a time of steel shortage.
540 lb for the amc 304-343-390-401 engine 601 lb for the earlier amc 250-287-327 v8 of the late 50s Comparisons: 350 Chev is about 540 lb 351w Ford is about 525 lb 390 Ford is about 675 lb all iron or 625 lb w/alum intake
---No, the International and AMC have two completely different bolt patterns. AMC's 304 was built by AMC and the IH 304 was built by IH. Furthermore, the IH 727 was built to IH's specs, so more than the extra steels and clutches, tighter tolerances and bolt pattern will make it different. The throttle operates a linkage that mounts to the transmission and operates a throttle lever on the transmission, which in turn operates the valve body. In other words, the Chrysler 727 is vacuum modulated and the IH 727 is mechanical. You'll never get it to run right without the linkage and I hope you took time to unbolt rather than cut parts out with a torch. ---As for torque converters, I have no idea what would/wouldn't work with AMC. AFAIK, the only Chrysler torque converter that works on an IH 727, when bolting to an IH 304, is the 10". It all depends on which engine the 72 Scout had. If the 72 Scout had a 258 6-cylinder engine, which was made by AMC, then the transmission will have the same bolt pattern as the AMC 304. It was a stock engine available in the Scouts.
Standard or optional? Standard engine was the 232 six. V-8s were the 304, 360 and the 401. the 304 and 360 had a choice of two-barrel or four barrel carbonation while the 401 was four-barrel only. "68 and '69s v-8s were 290s, 343s and a 390.
