Do I smell more upgrades? Maybe hitting the 90 mph!!

Kanookstr

Well Mark, it's like this..... New AFR Cnc Heads, and 731 cam. so far the numbers come up to be 844HP compared to the little 650 hp I had And if I seen 82 with 650 hp, I would think 200 more should put me well into 90 mph, or at least 89

28Eliminator

Kanookstr,
That is a nice increase in power. Are you still using the same procharger, or did you upgrade that also. I am at about the same speed and setup, only with a whipple, and might be looking at upgrades in the future. I think 90 should be no problem. I like hearing about projects like this.

Well, that's what Dennis Moore says in his book, but I think there may have been a change sometime around 1998. The Mercury service manual shows:

211/227 ; .512/.512 LSA not specified

Can anyone confirm?

Kanookstr

No 28Eliminator, I plan on running the same boost, so I'm staying with the same procharger. I will be recalibrating the ECU though

the 224/.483/115 cam is a carb mag profile. I honestly don't know what the later mag motors ran for a cam (not saying that it was or wasn't different, just saying the specs above were mag carb motors thru 1992 for sure..

Kanookstr

Ya this is the 1999 502 MAG MPI.
I know the cam part number, #431-850478
but it doesn't give the specs???
