I do have little money to throw around but not a huge problem, the engine is a 79.

Bowl blended closed chamber heads, (ported exhaust),straight up non retarded timing chain, dual plane performer rpm intake, 850 dp carb, Comp extreme 230-236 110 Sep cam, 2 inch headers, distributor curved for performance, three inch exhaust with Bullitt straight through mufflers.

There will be several correct answers to your question, this is just one I like to build,, and works great.

.080 over on the bore will give you 477 inches.

A Weiand Stealth intake works good on this engine as well as a torquer.

X2 ... a lot of it will depend upon the RPM range you want the improvement, how heavy the vehicle is, the gearing and the transmission.

To simply improve everywhere with mostly what you have :

1. get a "straight-up" timing set
2. Have the heads milled .060" off the deck and .030" on the intake flange while having a GOOD high performance valve job done.
3. get a shim kit for the pedestals to adjust the rocker arms to .020" lifter preload.
4, use a Performer, (not RPM), intake manifold; (block the heat crossover passage when installing it. You'll probably need to file some or all of the bolt holes for fitment).
5. get a 780 vacuum secondary carb with a manual choke.
6. have a shorter, faster timing curve put into the distributor.

Power will improve from "off idle' to at least 70 horsepower at 5,000 RPM.

On the inexpensive route you can search out a '68-'70 Thunderbird, Marquis, Continental. I just picked up the heads & intake from a '69 390hp Marquis. You can get out near 400hp with stock parts & little effort. The difference between your block & the '69 is deck height. I have a '76 Lincoln 460. It came with 8.0:1 compression. Just swapping on the older heads it will bump up to 9.5-10.1 from what I have read. You can also port them yourself for additional hp. Recurve the distributor. Just ordered the kit from a local speed shop. A whopping $5.00! Headers & low restriction exhaust. I have also read the 385's are thirsty with the factory carbs. I seem to be finding 750 dp as the carb of choice for mild street build. Early timing set to bring your cam back to 0.

So for my '76 220 hp 460 I am swapping out the intake for a C8 dual plane. I have no idea if this is any different that using my '76 intake but for the $27 I paid for it I am swapping it. Swapping out my smogger '76 heads for C9VE-A (standard pass car heads from '69). Yes you will want to run them through the machine shop & have hardened seats put in them. While you are at it have them put the CJ valves in them. Recurving my distributor & searching out a 750 dp to use. I am also doing the early timing set. I am expecting a considerable difference in hp. Pick A Part or Pull A Part is a great place to pick up the parts on the inexpensive part of life. Mine came out of a Pull A Part. The heads were $34 each & the intake was $27.

I hope you bought the rocker arm assemblies with those heads or you'll be spending some more money on stuff that will work.
