Let me know what combos may work. I'm fairly new to this, rebuildin a 73 swinger to look like a 72, wanna go fast.
No problem at all. Mike at MRL Performance built me a very streetable 340 that makes 470hp, has basically stock edelbrock heads and not even that big of a cam.
* WOW really? Tell us what was done to the 340.My stroked 318/390 made less than that..
Here's the thread on it. Major secrets are light pistons with custom ring pack, hydraulic roller, K1 H-beams, and a really good builder.

Here's a video of it in the car with a street roll of ~5-70 with a 3.23 ring in the back.

I'd say it cruises rich and I'm getting 13+ mpg city without trying. Idles nicely at 900.
That's cool I saw that video yesterday didn't realize it was your car. What size tires you have in the back, and many RPMs you turning at highway speeds? I have a 2.94 gearset for my Duster with 28" tires and I'm thinking of picking up some cheap 3.23 gears as it's a little too tall for my driving. Sounds awesome btw.Here's the thread on it.

To the OP back in the 1970s Chrysler developed the W2 racing heads for NASCAR which made over 1.5 hp/c.i. (600 HP) in a 360 so just keeping that in mind 500 is definitely doable with modern aftermarket 'street' heads. Just make sure you got the right gearing + trans setup.
boring a block .060 doesn't make hp,if your looking for 500 plus hp .030 would be better.
Right , not that hard , just that expensive .It's not THAT hard to make 500hp in a NA, stock stroke 360. Zero deck, flat top pistons, compression, ported W-2's, ported E-brocks, ported EQ heads (take your pick), a cam with 250deg @ .05 (or more), .570 lift or greater. At .060 over, hope cylinder walls are stiff enough.

Block was already bored when I got it unfortunately.
Speed cost money...........how fast do you want to go?
