Build me a 550hp 440!

How many boards is this thread on...LOL

I did reply to it on Moparts

As Running 11.9s:

30 over 440
steel crank
10.6:1 comp, (pump gas)
"six pack" speed pro slugs .017 below deck
915 iron heads stock valve size (stainless manleys) mild blend/port work
eddy rpm performer intake
mighty demon 750
swapmeet hooker headers
racerbrown 1.6/1.5 combo rockers
Racer brown 242@50 510 lift
3500 stall
410 gears 28" slicks
Holley blue pump, etc

I shift at 6K and the she shift light is just on when I hit the stripe.

I ran 12.4's with the only difference being I was using open 452 castings with stock rockers(would have made compression only 9.7 or so). That should have been close to 500 with the weight of this pig....LOL

No magic required to make good power witha 440, BUT it does need to be MATCHED.

Hope this helps!
