Title: AMC 360 Rebuld
Post by: gmshades on April 01, 2010, 03:15:28 PM
Thanks to selling some stuff on ebay, the money is coming in to finally get this motor worked on!
I\'m picking up the heads on Saturday. I\'ll post pics when I get them. The heads look brand new! He reseated the valves, put new valve seals in, resurfaced the mating surfaces, and repaired one of the exhaust holes. It actually had a broken tap in it. Danny in Honeoye is doing the work.
I\'ll be dropping off the block and anything else he wants to get going on the block.
I\'ve been fighting over what parts to go with for reassembly. So far, I\'ve done my shopping at Summit Racing, and have a wish list:
SUM-K8600: Summit Racing Camshaft and Lifter Set
EDL-2131: Edelbrock Performer Intake Manifold.
FEL-KS2001: Fel-Pro Gasket Set
FEL-MS96011: Fel-Pro Valley Pan Gasket
I think I\'m going to wait til its built to see if the stock push rods will work. Buying new ones either way.
Anyone else do some motor work that wants to chime in? I\'m all ears. Should be one heck of a motor when I\'m done.

I\'m interested in this buildup. I\'m running a cj7 with a 360 that I just bought. Runs ok so far but dosen\'t seem to have the nuts of a 350. One change I hear that is an upgrade is modern rockers. The originals tend to want to twist back and forth. this weekend I\'m pulling my covers to see what mine look like. Keep us informed.

I HAVE THE SAME MOTOR IN MY CJ!!!
It\'s a brute!! Sounds grumbly and pumps tons of power!
**** I\'m selling my Holly 2D Projection really cheap. The (new) computer is less than a year old, as well as the fuel pump. (the old computer got wet, and the fuel pump is new because we couldn\'t figure out a problem, and the fuel pump wasn\'t it). I have all the wiring diagrams and it is already set up for a 360. MAKE AN OFFER!!
I\'m also selling my 15 Gal. RCI fuel cell, connectors (all nice summitt anodized aluminum)and hoses (if you want them). MAKE AN OFFER!!!
I have the Edelbrock intake on mine, but the motor really doesn\'t need much, it\'s a beast!!! I\'m only geeking out on the motor because I don\'t see many of them, and I absolutely love it!!
Oh, and I\'m switching to propane for environmental reasons and peer pressure. My CJ on 36\'s with very good gearing (for wheeling, not street) got 18MPG with the projection.

Camo - are you still carb?
I thought I asked you on the Poker Run if you had a V8? I thought you said no. :-?

from the research ive done, one of the biggest upgrades to amc 360 is the ignition. DUI was a brand everyone seems to use.

my advice is dont cheap out and dont try to learn as you build your first motor. Pay someone that knows what they are doing to do it!
Im still fighting costly learning experiences with my small block build!

Yes, I\'m a 360 on a carb. I\'m trying to remember back to the days when I last had a carb engine so as to get the 360 running best. Injection and diesels the last 20 or so years. Air fuel spark exhaust, fine tune each and its all good.

Man, I wish I had the money in the budget for it. I don\'t even know what my total budget is on the motor. I was going to come on here and ask if anyone had a 600cfm 4-barrel carb collecting dust.
As mentioned, here are pictures of one of the heads. I\'ll let the pictures speak for themselves:

i have a holly 650 sitting i bought new and ran on the scrambler for 6 months.
im not going to lie, i had alot of issues wheeling with this carb, but on the street it was good.
i didnt have the patience or know how to get tuned right. also had some ignition problems at the time that didnt help.

Figure I would give an update.
The block has been bored .040 over. Crankshaft is .010 under and on its way back to the shop. All pistons, rings, and bearings are ordered.
I\'m having a hard time about my timing cover. Last year my oil pressure was perfect. But, the oil pump cavity has some scratches in it. I think this is normal wear and tear, and it should be fine for now. I\'d hate to spend money where its not needed at this time. I will be getting new pump gears. Any thoughts?
Anyone know the special \"assembly lube\" they always use on horsepower tv when they build a motor? I\'m thinking of the thick stuff they put on the camshaft.
As soon as I have more pictures I\'ll post them up.

its called camshaft breaking lube.. normally comes with the camshaft..
call Fermwood.. I just threw away what I had left of my tub.
Title: Re: AMC 360 Rebuld
Post by: rejeep on April 29, 2010, 08:24:19 PM
I would also suggest you use a quality break in oil with lots of Zinc.. (ZDDP) I use Brad Penn 30 wt break in oil all the time actually.. DO NOT USE SYN!!!!
you will ruin your camshaft if you dont.

Post by: Camo1Ton on April 30, 2010, 02:24:24 PM
I don\'t know if you have checked it out yet, but look into oil pressure issues of the amc 360. I have heard around that the scratches are not always the problem with pressure. Look into the external oiling setup that runs in the lifter valley. A drilled hole, some copper tube and fittings. Might be some good insurance at this stage of the build.
Title: Re: AMC 360 Rebuld
Post by: gmshades on May 01, 2010, 07:22:54 AM
I have thought about doing the external oiling setup, but I cannot find enough technical information to do this properly. I don\'t want to make trouble. Do you have a website with illustrations on how to do this? I\'m even willing to buy the \"kit\", but can\'t find that anywhere either.
Title: Re: AMC 360 Rebuld
Post by: Camo1Ton on May 01, 2010, 08:48:48 AM
There are too many places to find this info. Google it, or try amc sites, i think I found info in jeepforum.com one time. This is a start.

Block has been successfully bored out 40 over, and is going to be balanced this coming week. Taking longer than expected, but i don\'t mind when the quality will be there.

Wow. It\'s been awhile since I posted on this.
Motor is balanced and ready to go back together. I told him I need it by the beginning of next month. Hopefully he can come through for me. I\'ll keep you guys posted.

Here is the latest on the build to sum it up.
Heads were cleaned, then flattened. Valve seats were reworked. Then it was painted.
Valves were worked on to match heads, new valve seals installed. Original springs reinstalled.
Crankshaft sent out to be machined 10 under, and all edges were chamfered.
Block was cleaned, then bored 40 over.
New pistons, piston rings, and all bearings were ordered and installed. Whole assembly was balanced with the balancer and flywheel.
Order from Summit: MSD Black Cap and Rotor for an 89 Mustang 5.0. Ford Racing 9mm black plug wires. Set of 16 Lifters Summit K8600 Camshaft Royal Purple Assembly Lube
From Advance Auto Parts: NGK G-Power Sparkplugs Edelbrock 2131 Performer AMC Intake Manifold
From Ebay: New Timing Cover with Oil pump and cover. Hardened Pushrods
I talked to Tom and Dan, and they said it should be no problem picking up the motor next weekend. They are honing the block today, and will be assembling everything on the motor except the pushrods, intake, and accessories.
I am hoping to be pushing 300-350hp outta this thing.
I just know it\'ll be worth the wait.

I talked to the builders today. The block is honed and cleaned. Now its on the assembly line. Still looking good for Saturday to get it back and get the push rods on order.
The Edelbrock intake came in today. 21 pounds. I have a 600 cfm carborator from my friend for $50, so I\'ll throw that on and see how she runs.
BTW, any of you welded your spider gears? My friend should be doing it for me, but I don\'t know if he\'s gonna have time. Let me know if your interested or have any tips.

awesome!
Quite a few of us have welded gears. I have a welded up limited slip 10.25 rear, smike\'s 60/14 are both welded, at least Erik\'s rear 14b is welded, I don\'t remember the front\'s status but it may be as well.
My preference is not to weld to the case or cross pin since I don\'t want the heat to affect their strength - that\'s a debatable topic. I weld the crap out of the teeth, and then follow a trick I got from Gif and Loco to put a slug of steel in the square opening and weld all 4 sides of that to all 4 gears.
If you\'re running a 14b rear, the \"orb of traction\" is the way to go but be certain to have everything lined up perfectly, otherwise it\'s a bitch to get your axle shafts back in.

Well, about noon on Friday, the guys call me and said looking at the rockers, I should buy new ones. So I made an order for some, but they won\'t come in til mid next week. That makes it an extra week to order the push rods.
And today they had a family event, so they were not at the shop so I could pickup the motor. No big deal in a way cause I needed to order the rockers.
So, right now, looks like I won\'t make it to the Aug. 29 Manchester sand drags. There is the last one the end of Sept. though.
I\'ll keep you guys posted.

Got out of work early today, so went and checked on the motor.
They installed the heads while I was there. They were even able to measure for push rods, so they are on order now.
