360 cam and intake selction

[Texas charger 73]

so i'm building a 360 and looking for opinions

73 charger, headers, dual exhaust, 2800 stall, reverse manual vb, 3:55 gears
stock bottom end
587 or 596 heads

what would be a good cam and intake to run with this..

i would like some noticeable hp and torque. this is not a race car, just a weekender i want to enjoy and be decently reliable... current 318 in the car is unkillable, but slow

If you can find one a LD4B would work great. It was GREAT on my 360 tow vehicle motor with an aftermarket Carter AFB (Edelbrock now). Not sure how it compares with modern versions, but the runner size was great for my 360.

post up your compression check
really easy to kill low compression-non race- motors

Low compression engine?
Oooo boy!

My 360 was built with 9.5:1 compression, and ported heads with the 2.02"/1.60" valves, but built for torque for my RamCharger. 3.23:1 gears, 30" tires, and stock High Stall converter.
I used the Hughes 1620 AL cam (with 1.6:1 Rocker arms) and it worked out really nice.

I think with your higher converter stall and gears that cam should be OK in your 360.
The more stock fit (and emissions, if it matters) Edelbrock Performer would work fine.
The taller (non emissions) Performer RPM would be good and give room to grow if modifying the engine later.
Carb wise, a 650 cfm is fine. If you can afford the Sniper EFI use it.

Bottom. End was already redone and put together when I picked it up so I didn't get to chose piston, just took what was already done.

Stock replacement pistons then?
Well, if you can figure out your static compression ratio and we will assume it is holding good cylinder pressure since it is new, IMO, the probable low ratio isn’t a good thing for a medium size cam and that stall converter, which is a bit high.

A cam around 230 - 236 @050 would fit the converter itself but not the compression to support it right. Other missing information that would good to know is tire size.

I suppose, a cam around 224@050 would work pretty good in there. I’m running such a cam now in the wife’s A body Cuda w/a Edelbrock RPM & heads @ 11-1 - 360cid engine w/a 904, 3.55’s and a 26 X 10 tire. It works very well. My transmission/converter guys suggested a 2800 stall. I asked for a slightly tighter 2500.

The Cuda advantages are a bit lighter in weight and a higher comp ratio, intake and cylinder heads. Your OE heads are restricted in air flow. This would of course limit power potential as well as lift.

Here is the cam card below. It is a Hyd. roller. The HFT has lower lift that might be OK with a stock head. This I am not sure of. Regardless, I believe this type of duration would be a good candidate. Check out the various cam grinders for there versions.

If you’re looking for a new intake, I would decide on the cam first, then get an intake that’s on the same page as the cam.

The old LD4B and LD340 are pretty universal, but the Std Performer and RPM seem to work better when paired with cams suited towards the targeted application of the manifold...... milder for the Performer, wilder for the RPM.

No experience here with an Action+ or the Stealth on a SB Mopar.

If the heads are off the motor, it’s going to be worth figuring out what the actual CR you’re going to end up with, to help make a better decision on the cam.

If you’re going to run an adjustable valvetrain, I’d strongly recommend a SFT cam.

cc the heads
I just said post a compression check to estimate stock or lower or better
