Pro Comp headed 501 engine dyno'ed

Post  rmcomprandy on June 27th 2017, 7:58 pm

I thought someone might be interested in this.
This engine is for a street rod with an exposed engine so, these heads were provided by the owner as they are very plain outside and polish well. We put it on the dyno to break-in the cam, look for leaks and obvious things to be addressed.
The power numbers about knocked us over after we put-in the inner valve springs,
619 horsepower at 6,400 RPM and 582 lb/ft of torque at 4,600 RPM

4.390" bore x 4.14" stroke ... offset ground, stock 460 crankshaft
A connecting rod set from a 8.0 liter GM big block ... 6.696" long bushed small end to .990"
ICON forged flat-top pistons ... IC855/KTD
10.5/1 compression ratio
Bowl ported heads not flowed but, previous heads of this type are around 300/200 cfm
2.19" intake valves & 1.710" exhaust valves
Lunati hydraulic flat-tappet custom camshaft with their Micro-Trol lifters
  288/297@ .006" - 245/250@.050" - 159/162@ .200" - .359"/.362" lobe lift - 111 separation +2; 109 intake center-line.
  theoretical valve lift with 1.73/1 Lunati Voo-Doo rocker arms = .621"/.626"
polished Trick Flow "track Heat" intake manifold
Quick Fuel "black Diamond" BD-830 carb with electric choke
1 7/8" to 2" stepped primary - 3 1/2 collector 20" long dyno headers.

It is a shame this is for a cruiser / parking lot queen. He'll probably never use it.

In a nutshell would you say the pro comp is basically a aluminum DOVE head?

NO ... it has 93cc combustion chambers and a much better exhaust port.

A closer comparison would be to a production D2OE-AB Police Interceptor head but, having better exhaust ports.

NO ... I don't take photos of anything unless the customer specifically asks for it to be done.

It's purple with polished aluminum parts and chrome.
