WHOA!

She will make even more power than that.....I finally found a FMS A-460 intake ( quite a bit shorter and better for this size engine ) that will be going on it.....I also have to tune the carb in better as all of those pulls were running "slight lean to lean "......We will make some more dyno pulls after the changes are in.....I'm 99% certain we will break 850 FWHP this time out....

Nice #'s !!

How much head work? What Valve Sizes are you using?

These Trick Flow A460 big block Ford race cylinder heads are machined from A356-T6 aluminum and feature 340cc intakes, 172cc exhausts, 91cc chambers, bronze alloy valve guides, tungsten seats, big Chevy exhaust port openings and bolt pattern, and 1.760 in. spring pockets.


Assembled heads come with 2.30 in. intake valves, 1.88 in. exhaust valves, 1.640 in. dual valve springs for up to .850 in. lift, 10 degree titanium retainers, 10 degree machined locks, Viton® fluoroelastomer seals, ARP 7/16 in. rocker studs, and guideplates for 3/8 in. pushrods.


I used the heads "out of the box" no porting.....We did inspect them and flow test them though......
