350-375 hp 360 goal

[Texas charger 73]

i have a 73 charger and im buildng a budget 360 for it. my goal is at least 350 hp. here is what i got with the motor, stock block bored .40,stock crank,rods. pistons are sealed power(ch 1.576), cam is a Erson TQ20T(gonna get replaced), stock 596 smog heads with aftermarket springs,retainers,dampners and locks, LD4B intake(getting replaced as well),


who has had success with these heads. i hear the cc is between 70-72, gonna kill compression. i have been told to get a set of J or X heads,but i cant find any cheap enough so this what i got... i will be running headers,either a comp 260 or 280 cam,edlebrock performer intake,unless you have a better suggestion... im all ears guys...i was also told to add a windage tray,but my main cap bolts are bot set up for windage tray. gonna br running a thermoquad 850 cfm as well... should i replace the pistons and run the 596's or keep searching for the other heads? also was suggested to run magnum heads with oilable lifter and pushrods and the magnum rockers also going from 1.5 to 1.6?

Couple of things I'd mention. I've built 2 budget 360 motors and currently run a hot 340 in my 73 Roadrunner.
The 596 heads are fine but you are right about the cc. Get them skimmed down to 64cc or so.
Pistons. Sealed power do two types as I recall. Make sure you fit the higher compression version. No point in rebuilding another low compression motors and all 360s cam as low compression motors
I'd go with a Comp XE268 cam which will work with your heads/springs and will also work with a stock convertor.
Inlet, Air Gap if you can afford one or find cheap.
Headers will be needed and I have TTI but appreciate that they're hardly budget. Plenty of cheap options around.
Also, get a decent flex plate whilst the motor is apart and I wouldn't bother with a wind age tray unless your going around corners a lot!
Let us know how it comes together

You are at about 300HP with your present plan. Here is the proof.........

Make sure you read through, it even has the air flows for the 596 heads.

Now, what you should do beyond your present plan, depends upon your budget.

And by-the-by, I think the Comp 260 is a smaller cam that the TQ20

I'd skip the Magnum heads and do your present heads with 2.02's with a bowl port, the XE268H cam & headers. That's all you need to do.
