AMC 304 V8 "Max Bore 304" Build nearly complete! Almost ready for engine dyno time!

[@michaelcoger4626]

I raced a big bad orange Javelin in 1969. I ran at Motor City dragway in the old AHRA E stock optional automatic class. It was mostly 383 Mopar and 396 Chevelle's. It was fun surprising them with a Rambler. Won lots of class elimination trophies and winner stickers.

[@stanwatkins1877]

Some (too many) aftermarket cam gears get this wrong and cause distributor drive gear failure. To br sure it's right. Always use the Rollmaster p/n CS7110. It's a dual rollerchain type and as a bonus allows minor advance setup. Works great and no oiler mods needed.

[@MrRVRclubprez]

Some 360 heads require guide plates if converting from bridged rockers.

[@fooledman]

Love the station wagon I see there.

[@HowardJrFord]

BTW the bores need to be notched on a 290 - 304 when using 360 heads because the larger valves won't clear the bore .

[@leonardwalters154]

Love the fact that you are building the little 304's,everyone else thinks they are boat anchors, but that little engine is one of the most reliable I have ever owned, even at -10or-20 below 0 they have always started and ran with out a problem 😊😊

[@LucoreAuto]

We always like doing things a little.. off, plus they are actually cool little motors. With all the abuse we have put the 304 in the AMX through it's time to build a bit more of a "fun one" to see how that goes but we aren't looking to squeeze every ounce of power out of it. We drive our stuff so it NEEDS to work... and work... and work!

[@michaelfowler8289]

Can't wait 😮😊

[@yafois988]

Also there seems to be a lot of talk about the oiling tube install from front to rear for additional bypass oiling to assist areas bearing. Notice you didn't use this setup as I seen others use.

[@rolliefoster2837]

...pistons .026 down plus the head gasket thickness ? Seems like a ton of quench distance...

[@LucoreAuto]

We'll see how this works, we may end up swapping out to a thinner head gasket if we have to. Trying to get away with it as is and hopefully be able to run pump gas AND beat the heck out of it.

[@rolliefoster2837]

...sorry if my comment came off wrong, was not my intent...I'm a SBF guy & they do NOT like excessive quench ! Carbon buildup happens rather quickly & then you are fighting detonation no matter the static compression ratio - they seem to be pretty happy at .035 quench with the gasket bore .020 larger than the cylinder bore - spending $200 for custom MLS head gaskets has been money well spent for my projects ! Best of luck & really, really love this channel content !

[@edwardkamenar1493]

I had a 1972 Javelin SST that had a 304 in it. I yanked it and built a 360 to drop in it. Bottom end and top end. Got 425HP at the rear wheels when I was done. Great fan of AMC performance. It's really nice seeing people do AMC instead of all camaro's and chevelles for a change.

[@stevecr8934]

Never a bad day when your merch is flying off the shelves cause your fans want to show Lucore off. Have a Nice day.

[@ECC-ec]

Heads have guideplates ?

[@bunk57]

I love this motor, I'm glad to see you guys still messing with them. There isn't a ton of info on it so these videos are extremely helpful and interesting

[@trevorshackleton6546]

Did you have to notch the block with that bore I’m guessing yes using 360 head the valve will hit the block

[@WiSeNhEiMeR-1369]

HOWdy LUCORE, ... YAY - AMC Content for the 1979 AMC AMX = big Bore 304 How do the I-6 Cylinder Pistons work with the "304" V-8 Heads / Valves ? Maybe MARK the CAMSHAFT Oil Hole & Cam Chain Gear alignment "BEFORE" you install the CAM ??? ... LOL ... 480 / 480 Camshaft = you might want to "consider" running a 1.7:1 Exhaust Roller Rocker as AMC's generally appreciate a bit +MORE+ Lift & Duration on the EXHAUST Side ... IMHO = and = YES = I know = the 360 Heads already help the Exhaust ... COOP the WiSeNhEiMeR from Richmond, INDIANA ...

[@zerocontent3171]

Can't wait to see you fry the heck outa the tires.

[@LucoreAuto]

There's an above average chance that you'll see that soon 😉

[@christobaldaetz6062]

Nothing says America! Like AMC! Happy Birthday, America!

[@LucoreAuto]

That's pretty much exactly what we thought too! 😀 👍

[@MrRVRclubprez]

Widen the oil slot on the timing gear, it doesn't need to be so narrow

[@LucoreAuto]

Yes indeed, widened to improve oiling! Gotta make sure she's not oil starved anywhere!

[@MrRVRclubprez]

@@LucoreAuto I run roll master timing sets, with torington bearings and 360 degree oil recess.

[@kennethchapman9564]

My 428cj ran forged 12:5 to 1 domed pistons from TRW which are no longer available. With the heads shaved it was about 13:75 to 1 compression ratio and was on a diet of 106 octane low lead aviation gas. I remember getting compliments from the guy doing a front end alignment after rebuilding the front suspension with new manual steering gear box. I am gear head enough myself to admit that gas smelt good. The paint marking is a really good idea. I could have used that idea when adjusting the flat tappet solid lifter camshaft.

[@peterkovacs8654]

Happy Birthday America! 🇺🇸

[@LucoreAuto]

Yes indeed Sir! 'Merica!

[@mikebrown4429]

Did you use the short pipe plug in the oil galley on the pump side of the block ?

[@scottymartin1496]

Happy 4th guys

[@LucoreAuto]

Happy 4th to you too Sir!

[@ashqelon7267]

With all you did I would have thought you would address windage tray , crank wiper IF you use one, the clearance on mani journals known these need like #1-4 main 0.002", #5 main 0.003". What rod clearance you chose for this.etc. Additional oil pan capacity.

[@morton2200]

Did you have to machine the pedestals on the heads for the 302 roller rockers or are they a direct bolt on?

[@LucoreAuto]

Direct bolt on just need the right size studs. Fortunately that's a simple enough fix with about $100 worth of ARP bits 👌

[@aprilsfoolracing4594]

@@LucoreAuto what 360 heads are that if You don't need to machine the rocker pedestals? If anybody are doing the rocker swap and have to machine the pedestals BE AWARE when machining those that are for the 2 center exhaust rockers,it can be tempting to run the mill straight over from the first to the other one DO NOT DO THAT!!! "ask me how I know" AMC heads are the only one's I know of that has a water channel above the 2 exhaust runners where the EGR channels to the intake goes... And finaly : guide plates, DO NOT belive those sellers that says You can use Pontiac guide plates on an AMC,that's not true,they will not line up at all and to use them You have to cut them apart to align them and then weld them together again... There are seller on E'Bay that sells correct ones,and they are a perfect fit for alignment and they are pretty cheap to buy.

[@UncleRoots413]

You got my attention now. Have the AMC logo tattooed on my back. Someday ill build me an AMX in some fashion, hopefully a 70. Maybe two fashions, race and street, one of each if I could.

[@thisisyourcaptainspeaking2259]

Someone has a dyno capable of bolting to an AMC? Thats a find, right there.

[@zerocontent3171]

Any good machine shop that's been in business for several years should be able to dyno just about anything .

[@thisisyourcaptainspeaking2259]

@@zerocontent3171 I hear people asking which 727 transmissions will bolt to their amc quite often.

[@LucoreAuto]

Just a matter of finding a flywheel for it (we have one) and getting the cart modified to the engine mounts. No biggie 😀

[@johndillinger8482]

i didnt see a degree wheel,what was the cam timed at? no porting of the heads? what do you think your redline is going to be now? 9 to 1 comp with that cam isnt a good combo. with that cam,you really need to step up to at least 410 gears.

[@aprilsfoolracing4594]

I do not know what part number their 360 heads are but the heads with the part number that ends with 502(1974 360/401 heads) flows 226 cfm@ 28" of water @.500 lift on the intake (228cfm@ .600 lift)absolutely untouched,and if You know what You are doing they can be ported to around 300 cfm,but again "IF You know what YOU are doing" it's easy to go wrong when porting a AMC head,they are NOT Chebby heads...

[@dave.harmon]

I still want a founding member shirt, but you guys still don't ship abroad

[@BucksSuperStereoWorld]

See? You think just like I do. I really enjoy building engines that no one else shows any attention to just because there's an easier option for power. People call me crazy for this dream, but I have ALWAYS wanted to build a Buick Straight Eight and figure out a way to design a crossflow head, design a sheetmetal intake manifold with multi-port injection (one injector per cylinder), a huge throttle body, design a two-piece long tube header for it, bore and stroke it to the max, and put a large turbocharger on it. Don't ask me why I want to build that engine combo, but I just think it'd be awesome to build that engine and mate it to a Tremec TKO.

[@LucoreAuto]

Well there's nothing wrong with being crazy 🤪 OR doing things differently than "normal"! Cheap easy and common is boring! Fortunately for us, MOST of the AMC stuff is still reasonably findable. Bored and stroked straight 8 Buick would certainly be a WHOLE lot more custom!

[@BucksSuperStereoWorld]

@@LucoreAuto Definitely agreed...lol

[@tombrewsaugh1399]

What's the latest on your Capri build now that you mentioned road racing? I'm interested in seeing some updates on that build as that is how I found your channel.

[@LucoreAuto]

The block and heads and back from the machine shop just need to get assembly done. Once the 2.8 is all assembled we'll break it in and tune it on the engine dyno just like this 304. Still hunting for a "donor nose" to section into the race car though since we decided to keep the lil green car in one piece.

[@Georges73]

Hello you most take a microfoon for the sound so that we hoir you beter whit all the noses there in you garage.sorry that i tel you this what you most and not most do on your channel. But it is a hint. Love your channel very machs. Greeting from Belgium and my Georges.

Take your shorts and keep them where the sun don't shine! I don't want to see them. YT has figure out quick money is all. 30 seconds of adds in front of a 60 second video that took 10 minutes to work on that you could have easily said in 5 minutes.

[@HowardJrFord]

The late Herman Lewis , famous AMC racer and AMC engine builder recommended drilling a 3/16 hole in the front left side lifter galley plug to eliminate any problems with distributor gear oiling . His 69 AMX was the world's quickest super stocker at one time .
