Default RE: 400HP 390cid.

How much is your budget? 400 to 450 HP is not exactly cheap. Tell me what mods you have now.
mtl. cost estimate only:
For sure you will nead headers $400
Edelbrock RPM Intake $290
Cam $150 $250
Heads $300 to $1300 ported or new Edelbrock
2-1/2 inch exhaust $300 to $400
solid lifter Roller rockers $800 or more
Carb $300 to $450 around 750 CFM
gaskets misc???

I would also suggest changing to a higher ratio rear end I have a 3.70 at 55 mph runs about 2650 RPM

1960 HT 390, Edelbrock Performer RPM Intake, Shorty Headers, 2-1/2" Exhaust and 3.70 Rear Gears
390, Mild Cam, Headers, 3.70 rear, 2-1/2" Exhaust, Edelbrok Performer RPM Intake, Holley Street Avenger 670 Carburetor, One Wire Alt, Petronix Ignition. She's All Go and No Show.
