360 Rebuild Advice Needed

Hello fellow FSJers: I am in the process of rebuilding the 5.9 360 in my 90 Grand Wagoneer. I would love to have input, suggestions and any other advice from you guys.
The ultimate goal is to have a reliable motor for road use only (no off-road/towing intended in future use).
My buddy and I pulled the motor a week ago (some of you may have seen the pic in a previous thread) and the motor has been tore down and machine work is currently being completed on the block and the cylinder walls are getting bored .030 over. The bearings looked very good, not much wear and the crank also looked very good. I was curious as to where everyone purchased their parts…? Has anyone had any luck with Summit’s “Master Rebuild Kit” which includes pistons, rings, bearings and gasket? I plan to purchase the cam and lifters as well – any suggestions where to purchase those? I noticed in a previous thread that members thought the Summit Cam would be the best option. Here are the other parts I plan to purchase and would like input as to where the best place to purchase the parts for my intended use would be:
Balancer
Cam&Lifters
Timing Set
Water Pump
Mounts
Valve Springs
Valve Seals
Intake Gasket
Oil Pump Rebuild
Alternator
I have already purchased a new 2150 motocraft carb from the individual in Colorado Springs that came highly recommended by other members as well.
Any other suggestions are greatly appreciated! Also, please let me know if you need any further information to help you better answer my questions!
Thank you so much,
John

See this thread for how I built mine up.

http://www.ifsja.org/forums/vb/showthread.php?t=123219

I had to tear into the bottom end a 2nd time due to a worn thrust bearing. Shop said it could have been due to a bad torque converter. I replaced the torque converter, fixed the crank and put new main and rod bearings back in and it's been fine since then.

Thank you

Thanks for the suggestions. I will replace the oil pump housing as suggested. Any advice on where to purchase parts I have listed?

Thanks again,

John

Based on some suggestions I got from this forum, I got my kit through Mad Dog Racing.

http://www.hdmaddog.com/AMC-Jeep-Hud...-p9739263.html

I haven't gotten to assemble it yet, so I can't give you an honest "been there/done that" opinion.

I got my pistons from Mad Dog Racing, as well as rings. I may have gotten the gasket kit from them, too. I don't remember.

I had the shop install the cam bearings and all the freeze plugs for me.

I'd give the machine shop a chance to match online part prices. If they supplied my parts, I'd have the local shop to deal with if anything goes wrong ... rather than a distant reseller. Plus the shop will give me advice on which parts and brands to buy, and I wouldn't have to carry the parts to them for fitting. Don't forget to figure in shipping.

If you need a timing cover (ie the oil pump housing), BullTear would be a good source. But, you can measure the housing to see what condition it is in. IMO there's no reason to replace parts that are not worn out. The FSM/TSM tells you how to evaluate the housing. Housings can often be reconditioned without a lot of special equipment - Ristow has a thread showing this, as well as how to measure the clearances in question. http://www.ifsja.org/forums/vb/showthread.php?t=106458

We need a "Ristow's stickies" forum.
