Response to Ported intake and heads !
Hello Tom,

Here's some info on the cam.
Also Dyno test results for a 350 w/this Cam.

Comp Cam Extreme Marine Hydraulic Roller
Part # 08-417-8
Grind- XM270HR

RPM range 1200 to 5200
valve lift- (intake) .495 (exhaust).503

Here is an example of similar power and the Dyno test results for a 350c.i. w/ Dart S/R heads, performance intake manifold and header exhaust. The test motor had 9.25 to 1 compression ratio. My 327 is 8.6 to 1. and stock Q intake.

Results of the 350 Dyno example:

Max torque @ 3800 RPM- 415 ft lbs.
@ 2200 RPM- 350 ft lbs.

Max H.P. 342 @ 5100 RPM

150 H.P. @ 2200rpm
200 H.P. @ 2750
250 H.P. @ 3500
315 H.P. @ 4000
342 H.P. @ 5100

You can access additional info from the Comp Cam website under Tech pages.
Sample Dyno charts and graphs as well.
