RE: Cams, cams, cams

Nick,
I agree with some of the others here; 450hp on a limited budget 390 is hard to do.
Here are 2 dyno combos I know of:
First is Mustang Monthly June 1997
390+.030=396
9.8 compression
Edel RPM Heads
Edel RPM Intake
Edel 750 carb
Edel Perf RPM Cam 236-236 dur at .050
2-1/8" headers

Result:
418 hp at 6000
434 tq at 4000

(I think the headers were too big & with a more forgiving 800 double=pumper this engine would have made about 435hp.)
But - did you ever HEAR this cam run?
I have! It's ROUGH. Marginally streetable.

2nd article:
Hot Rod Jan 2003
390+.030=396
9.7 compress
Edel RPM heads
Edel RPM intake
Edel 800 carb
Crane Hyd Roller 222-228 dur at .050
1-3/4 headers

450hp at 5600
460 tq at 3800

....oh by the way Hot Rod priced it out at $6,044.21

It ain't easy to make 450hp from a 390, the 427 Med Riser's "only" made about 470hp (with 11.0 comression!), making 450hp from a 390 is hard no matter what.

But these are the real dyno tests I know of.

Now, I have seen 390-powered Mustangs and stripped (3400lb) Galaxies run at Milan Dragway in the 11's on a single quad - that takes near 500hp no matter how you cut it. But, wild engines. Not streetable.

What would I do?
Build the engine, late heads and all -
then get an Edel RPM Intake & 750cfm carb, Edel or Holley
THen add 1-3/4 or 1-7/8 headers, NOT bigger.
Then add a cam, either one of the ones above or like Comp Cams 270S or 280H or 282S
Then save up for the Edel RPM heads.
Now you will have 425hp or so in a streetable "396".
