bassdude,

I couldn't find valve open/close specs on your cam but it looks like EPWI probably uses Comp Cams pieces with their name on them, so I subbed in the Comp Cams X256H numbers (the specs closest to what you listed). For those who think it takes radical cams to make good numbers, you should pay close attention to the torque curve this mild cam produces.

RPM HP / Torque
2000 208 / 546
2500 262 / 549
3000 314 / 550
3500 364 / 547
4000 408 / 535
4500 435 / 507
5000 439 / 461
5500 417 / 398

Look at the big, fat torque curve. That's 500+ lb-ft torque on tap from just off idle all the way up to 4500 rpm. Now THAT'S useful torque - Very nice!

I played with things to see if I could tweak the numbers a bit, but it looks like your combo is pretty solid.

Brad

WOW!!! Thanks brad i'm really glad to see those kind of numbers. i let the machinist i used pick the cam for me. i guess it pays to deal with poeple who know what they are doing. thanks for your time and effort Brad. man, i really can't wait to get this in my truck!

John.
were the rpm's the same as the chart Brad posted? those are some low rpm's on that torque figure for that big a cam.

77460ford is gaining momentum as a positive member of FTE.77460ford is gaining momentum as a positive member of FTE.
The chart didn't start on the last pull until 3750rpm but showed the following:
RPM HP Torque
3750 324 453.8
4000 330.5 434.0
4250 329.0 406.5
4500 321.9 375.7
4750 316.8 350.3
5000 322.8 339.1
5250 330.6 330.7
5500 338.5 323.2
5750 345.8 315.9
6000 343.1 300.3
6250 344.3 289.3
6500 334.8 270.5

We spent over three hours strapped on the dyno with jet changes and timing adjustments and tweaking different little things. I'm happy with the way the motor works and the low ratio gear set in the C6 really help with a good launch. I hope to get to Grand Bend on a test and tune night and try the 1/4 just out of curiosity.

John.

Actual flwhl numbers for CID473's 473. Lots of ***** through the mid range, plenty at 6000, and a whole lotta fun.

See bassdude's combo that I DD's earlier in this thread. It's looks like a pretty solid low-end torque setup.

Most of the current crop of split duration cams in the 255-265 range will probably fill the bill nicely. Great power without sacrificing any low-RPM response or daily driveability.

Ditch the double-pumper. Get a good vac secondary 750. Easier to tune.

Brad

I too am building a street 460, looking to make a lot of torque. So far I've ported,polished, bowl blended a set of d3ve heads and they are at the shop getting new stainless 2.19 intakes and 1.76 exhaust valves. Going to do the head work to figure out what the best pistons,cam, and cr. To use to get the most low end torque
