Have you ever actually set eyes on an AMC engine?  Since when did the AMC become a big block?  It is the same rough size as a small block Chevy and lighter. AMC DID NOT MAKE A BIG BLOCK EVER!!!!

Hahaha you guys are a trip. I was asking about the rear end because I haven't had a lot of experience with the amc rears. And yes the amc engines are high in nickel but then again so were most engines in the 70s but the internals are weak. The crank can't handle 700hp safely and there aren't any aftermarket cranks for the 360 u have to custom forge one or cut a gm crank to fit and that in itself completely defeats the purpose of keeping the original 360 to begin with. All your doing is putting a mask on an ugly kid. The heads were strong yes but not better that 99% of the competition with a mild port. Your a little off there. The fact is if your happy with what u got bring it to the track in a couple months and I'll show you real power. The engines were adequate for what they were and I'm not arguing that. Fact is there's a reason the "big 3" ARE THE BIG 3 and it's not beCause AMC had a better engine than they did.
Dear Mr and Mrs Honda no this is not a Mach 1 and yes I will embarrass you on the strip.

This is getting ridiculous! I think you guys are arguing with a high school kid. ICEs all pretty much fall under the same constraints no matter who made them. Factory parts are limited in strength because all they are designed to do is get mom and pop around reliably, with a little extra strength for reliability. Performance is and always has been a side show. Build big power and nearly everything must be changed, doesn't matter about make. Some specific items are weaker than others, just depends on where the engineers decided to compromise. The small block Ford isn't strong enough for a lot of power, 500 hp is about the limit for a factory stock block. An AMC 360 is a good bit stronger. Pick parts to build what power you want, and sometimes that will mean an aftermarket block. Anyone who knows much about engines in general knows this. The guy you've been arguing with apparently doesn't.

The Gen-2 and Gen-3 AMC V-8s are basically small blocks. As such they are some of the stronger small blocks around. They are sometimes referred to as "mid blocks". They share all but one general characteristic with GM/Ford/Chrysler small blocks. That one exception is the bore centers. AMC used a bigger bore center, by coincidence the same as Chrysler big blocks (that's why Chrylser BB aluminum heads used to be drilled to fit AMCs by drag racers before a real AMC aluminum head was available). The only reason they used that bore center is because the Gen-1 AMC/Rambler V-8 used them. By keeping the bore centers the boring tooling could be kept as well, saving a good bit of tooling money. The old Gen-1 more closely resembles an FE Ford or BB Chevy, but was only 250/287/327 inches.

The big three are the big three because they were bigger and had more money to work with. It wasn't always that way. There was a lot of consolidating after World War II, and other things happened about the same time (rationing materials, etc.) to really shake out the auto industry. AMC was the only small company to survive because they had well engineered products. The heads of AMC made a lot of bad business decisions starting in the mid 60s. THAT is what drove AMC down, nothing to do with engineering. In the early 60s AMC was competing successfully and had a surplus of cash. It took the next guy in line after Romney about three years to spend all the surplus and alienate AMC's bread and butter customers. THAT did more harm than anything -- AMC never really recovered from that. A few mistakes later and they were on the skids. The Pacer turned out to be a mistake, but only in hindsight. At first it sold well, faster than AMC could make them, then the first oil crunch hit and killed sales. The Pacer got no better mileage than other mid-sized cars, but was a bit less roomy. Plenty safety features though, which added lots of weight, and killed gas mileage and power. So people went to smaller, more economical cars and left the Pacer on the showroom floor. The Matador Coupe was another mistake. Shared only drivetrain and some minor components with other cars. Did make a better NASCAR racer, but didn't bring droves to the showroom. It was costly to produce. In the early 60s AMC had a nicely integrated product line that shared as many components as possible. Lee Iaccoca followed the same route to revive Chrysler with the K-car and derivatives. It's economical and works. AMC forgot that and tried to make a wider variety of cars than it could really afford, but you don't know until you try. Hindsight is 20/20, in business you have to look to the future -- and sometimes you just don't get it. AMC just wasn't big enough to absorb the big blunders that GM and Ford made -- Edsel, Vega aluminum engine, X-cars, etc. -- many more than AMC ever made, and bigger ones, but able to financially absorb the losses and keep going... at least until now. Now they are having problems...

Not really arguing with him.  Just educating and entertainning.  I like the way he came back with the juvinile lets race comment.  If the car he speaks of was ever built he wouldn't be allowed to drive it without a license anyways.  It's a slow day at work, let me have some fun.LOLLOL

Hi, can anyone tell me if a stock 1970 Ford 9" rear can handle 1000 horsepower?  I am thinking about putting a F-16 GE F-110 engine in my Pinto and was wondering if I can break the sound barrier in it?

On another, less family friendly, forum I use - they have an emoticon where a hand is stroking something.  I think that pretty much sums up this entire thread. **
So pretend I inserted that emoticon here and we can wrap this thread up until we see timeslips.
