@meatybtz 3 года назад

A little secret AMC I-6 have a second harmonic zone beyond the Red-line. If you can spin it past the breaking point fast enough you get into another level of stable harmonics that give you double the RPM peak. AMC experimented with that back in the 60s and 70s for racing. F class racing. The sound of an I-6 spinning at 9K RPM is something else...

@maxjordan2625 2 месяца назад

Damn fo real??

@meatybtz 2 месяца назад

@@maxjordan2625 yes. It was done, apparently more times than even I knew for things like Indy car motors and also in South America for one of their racing circuits. It's actually true of any reciprocating assembly or reciprocating ICE. But there really isn't a point to it unless you really need to and it's expensive and fragile. Lots to go wrong. Lots to stabilize.

A few years back I had a '91 Wrangler 4.0 HO. I did a lot of the same upgrades that you did to this engine. I went a few steps farther and polished the intake/exhaust ports on the head/intake/header, roller rockers and lifters and like you, upped the camshaft a little. I also added a larger diameter throttle body and a few other goodies from Summit, 4WD Off Road etc. like a nice electric cooling fan and distributor etc. Nothing too extreme. Unfortunately I did not have a before/after dyno to see the actual results. But I can tell you that the good ole' seat dyno and even the MPG were a lot better than before. Too bad I sold it.

In any case, I hope he is doing ok and I wish him and the new guy the best of luck.

@dewholdingsllc1050 2 года назад

👍🏼 Thanks for the AMC inline 6 content. I have a project Rambler Classic Convertible with the 232 2-V carb. OEM service manual says it’s rated at 155HP. However, you show me most likely to expect. I am very glad to see you can do an easy refresh on these engines and boost up the torque and HP. I also chose the upgraded 4-V, dual plane intake with small edlebrock. Exhaust manifold is not easy upgrade as on AMC cars the starter motor is on the left hand side, not right like Jeep. I am thinking about trying a 80s AMC Eagle exhaust manifold.

Don't know if they're still around but I rebuilt my '81 CJ-5 258 using a cam, intake and exhaust from a company named Clifford Research. They're logo was 6=8. They specialized in inline engines. Huge difference. Ran better than stock V8s. Topped it off with a Holly 390 4 barrel. Exhaust was a 6 into 3 into 2 duel pipes. Never seen that kind of low end torque. It would idle up a cliff.

8.3:1 compression? Come on guys! You had it apart, so how much would you have spent on some cast pistons to give it 9.5:1 compression? Less than half of what you spent on the intake manifold. ANY time you already have an engine apart, you should ALWAYS replace/upgrade internal parts before external parts. Now tear it back down, put some flat top pistons in it (for $100 more?), mill the head. 0100, then bolt it back together. I bet you get 220 HP, which is what you should have done in the first place! 🙄
