new 360 advise needed please.

so i've never been real happy with the motor i have in the dart right now.. i want to put together something a bit more mild that is more a cruiser.
i'm going to try to get signed up for the Sick 66 (Edelbrock Sick 66 — Sick the Mag) event and participate in the sick ward part of it. no need to race the car... if i can get in we are looking at a 4000+ mile trip in october so this thing has to be simple and reliable. i'd like a little pep to it too but nothing crazy.. i could spend nothing and just take my 08 mustang and be more comfortable but what fun is that..lol


my plan is to go through and freshen up the 360 that came out of my yellow car. its a box stock 74 360. its a pretty low mileage motor so i hope i don't need to bore it and will reuse the stock pistons (hopefully). trying to keep costs down as much as possible..

like i said it needs to be more a over the road car.. i think we will enjoy it much more that way.. use it a ton more too..

what i have already that will be reused..

70 dart.
3.23 gears (may go to 2.94)
26" tires
904 trans, its in the car and nothing needs to be done.
9.5" convertor that i'll just call dynamic to tighten up some.
small valve J heads
performer RPM intake
stock 340 manifolds.
full TTi 2.5" exhaust with X-Pipe
MSD rtr dist. in the car now.
multiple carbs i can use.
the bottom end will be as stock as possible. if replacement pistons are necessary then i'll buy stock replacements in the bore size i need.

i don't mind running 93 pump gas in it if i have to but 87 would be nice to be able to run..

i think my biggest question is about the cam. i'd like something a little bigger then stock but nothing crazy. i have two brand new ones here laying around. a old MP 340 replacement cam P4452782 (Mopar Performance P4452782AE Mopar Performance Purple Camshaft Kits | Summit Racing) . and have the hughes seh1620al-12 (https://www.hughesengines.com/Index...110&searchmode=partnumber&page=6&partid=30239). a couple friends think the hughes would be great for what i'm trying to do.. my question is, its a fastrer ramp and .503 lift. will that be reliable long term or is it harder on parts? or should i be looking for something other then what i have? i have no problem ordering a new cam.


if i need to provide more information then what i posted please say so....

I would say run the Hughes with good valve springs.
Yup, having to run 93 or 94 is expensive now. Especially when looking at a 4k mile trip. Think about a water injection instead and use 87 fuel. For the summer you can run distilled water with just a bit on water soluble oil to control detonation. The water injection kits have a vaccum switch to turn the pump on when the vaccum drops. For the winter, put some methanol in and drive it before parking it to prevent freezing.
