When this project started reliability was the Highest of priority with a stable long life valve-train and a target HP of 800HP was the Goal@6000rpm. I was willing to sacrifice max hp for reliability Motor is sitting in my shop with short block assembled, camshaft installed ready to bolt together. Unfortunately I have lost interest in the project. I let myself get led along by Bobs BS for over a year and finally had to distance myself from him. What I found interesting was how quick he was to point to others for his repeated failures to deliver as promised. I have since spoke with a couple of individuals Bob pointed to with fault and it turns out Bob is the one not them who didn't deliver. Not a Fan of MK done with this jerk off. |

That`s a healthy cam with some lift , I like it . what do you run it up to? Ever dyno it? Whats it idle like?
Need more info :D 555ci JC Performance/Smith Power Brodix 2x heads Roots blown 6lbs boost 262/272 112 LSA 109 ICL 708/708 Crane solid roller cam, lobe designs from track roller profiles. Using same cam in a 573 now Tried Comp Cams same specs, made more boost but less power so numbers don't always tell the whole story. |

On the 555cid; ran at 5900rpm WOT. Made over 850 at 6300 on Brad's dyno. Have a short video of it idling but cannot post it, says it's too large; it idles at 1100rpm, 700rpm in gear with no surge. Doesn't matter which carbs either; same idle using three different sets (differing CFM), it's easy to tune. I should mention that the Comp Cams steel billet cam was ground on a 114 LSA. I think that's where the boost was gained and where the power was lost in this combination.

Seems like whomever picked that cam, may have known a thing or two. Bet it made pretty good power too. I did use the BB2X flow data, with CNC ported chambers. Not sure if you have that, or any chamber work, either way, fun stuff. |
Would be interesting to see dyno numbers with those already listed, assuming they've been dyno'd

First one was mine 630 hp and 638 tq in marine trim

I have almost the same setup as you do. 540 -315 AFR heads. The cam is 246*-250* at .050 >663-.654 lift. 112 lc. Can you post what you replaced that MK cam with and what the result it made? I am going to rebuild and might make a change.
