Your comment reminds me of a guy I worked with. He had a '37 Chevy street rod he sold to his nephew. The car had a 350 in it. The kid pulled the 350 and slipped in one of the 4.2 Twin Cam inline sixes GM built in the 2000s. He was at a meet up one time and somebody asked how come he put the 4.2 in it. His answer was any idiot can stick an LS in. That aside if the owner wanted to go big power, then swap an LS in. The 304 was turd from day one. Low compression, small valves, two barrel, smog cam and possibly in this case an air pump with lines to the exhaust manifolds. With an LS there so many options as far as heads, intakes etc that building big power isn't a problem. I take it the owner here just wants a little more punch. One thing I think sould have been done is run an extra oil line to supply more oil to the #4 and #5 main bearing. The oil galley on the right side intersects the lifter bores and the feed from the galley intersects the cam bore before it gets to the mains. The oiling system is fine for street use but any thing beyond that that involves high RPM it falls short. I wonder if there is enough meat in the webs to add a second feed line to the main bearings from the left hand oil galley on these engines.

These engines were not honed in the main bearing bores. But if a block was found to have a slight bore mis-alignment they would be honed off line by hand. The pistons were not one size fits all. After the cylinder bores were honed they were measured and the size denoted by letters A-F iirc. The pistons were also sized A-F. The difference between each letter was .0002". One needs to remember holding really tight tolerance with 1960s era manufacturing technology on a production line is extremely difficult. The cam bearings on these engines, in fact all AMC engines were installed undersized and line bored in place the same time as the main bearing bores in the block.

We put headers, edelbrock cam/intake/carb set and a 0.010" clean up bore on it. With a rebuilt transmission and 2200 stall converter, that little car would leave a nice set of double stripes on the pavement afterward. 30 years later he still has that car!

According to the internet a 1970-71 AMC 304 gross rating of 210 hp and a 1972 AMC 304 SAE rating 150 hp was measured with the same engine combination...just the rating at the flywheel was measured without any drive accessories(1970-71)...and then with full accessories and full exhaust -(1972). Keeping 8.3:1 compression will allow this engine to run great on as low as 87 octane and if someone wants to boost it or put a small shot of nitrous to it later it will work well, too. This will be a great street engine and best of all they used the original engine from the vehicle. If the wanted they could have made way more power but this is what those Detroit Muscle guys asked for. Solid build.

You actually run into some interesting problems with the AMC 304, especially right now. As they state in the video they used a .060 over piston, those are almost impossible to get ahold of right now. We know, because we're building a .060 over 304 right now for our 79 AMX :) Sealed Power is sold out and won't be back in stock for 2-3 months and the only other option is from UEM and those are also a factory stock replacement unit around 8.5 : 1. The only other other option really is to go for a set of custom pistons at about twice the price. But, when you are throwing $5500 in parts at this build, why not spend an extra $300 on some better pistions?

All I did was put on a set of headers and Cherry Bomb mufflers, remember them? and wider tires, I went through more rear tires and you can imagine, lot of fun. All I will say is the brand new 74 Corvettes could not beat me in a race. Sadly put it into a telephone pole, drag racing of course. A lot of fun while I had it though.

Love watching these shows and I love the way that you guys are well presented and don’t look like Yosemity Sam like so many other on other competing shows. Also so shop is clean well lit excellent knowledgeable narration an strait to the point plus excellent camera work. Keep it up guys. I’d love to see you deviate from your regular v8’s and 6’s to a Dodge v10 or some Vw or other 4’s, or even a straight 8.🇦🇺

This thing runs sweet as it is... I'd leave it as is, take her out an play with her. As that engine sits, it is extremely street-able, reliable and can probably run on 87 octane no problem.

Greta build! Have to do a BUICK 455 build next. Please put 10.5:1 compression in so it's pump gas friendly and won't leave power on the table. They make loads of torque and shake the ground.

It’d take 85 without too much timing. It seems the senior builder wanted to limit the timing in the video as well. Should be super streetable and non temperamental.

This is a really cool and unique build. But I'm really surprised they didn't get some pistons that would have added a little more compression.
@edim108 2 жыл бұрын
With that compression and EFI this would be a Killer setup for turbo or blower! Lower compression means more boost before self detonation becomes a problem and EFI means precise and consistent air to fuel ratio across the board.

I was taught about 55 years ago to not lube bearing surfaces all the way to the parting line. Bearings don't need it for assembly, and it could allow the lubricant to squeeze out onto the mating surfaces. If you're actually concerned with tolerances to the ten-thousandth of an inch in bearing diameter, this will throw off the OD as well as help allow the cap to walk now that you've greased it up.

I was looking forward to the promised "I want to put it on the dyno before we do anything to see how much driveline loss there is". To bad they weren't able/didn't run it on the dyno before the rebuild. It would have also been nice to see how much power was being robbed by that 70's era AC compressor.
