So Im thinking of maybe changing my cam eventualy to get a little more out of my low compression 440. its a 77 440 .040 over with 452 heads and the old 509.
As of right now the 509 doesnt do too bad, but i figure with so much duration and low compression i could get more out of it with a different cam. If anyone has any suggestions Id love some feedback

 

Something like this..... I really like these cam... Good all round Vacuum for power brakes and great idle. Best power out there....
Lots of choices...
just my 2 cents

 

If you wanted to bump it up some maybe 1.6 rocker arms Definately would need the valve retainer to guide clearance checked
