Are these Cam specs mild or wild for a 454 merc?
 
MERCRUISER # 431-850478 / GM#12551622
.004 300*/ 300*
.006 288*/288*
.050” 224*/224*
.200” 125*/125*
Lift .483”/. 483”
ICL 109*
LSA 115.5*

Want to put it in my boat with 511 EMI headers and thru hull exhaust
with a new intake yet to be determined,

its a 98 crownline 202 454 merc and brovo 1

Is this cam to big to small just right??? Thankyou

Quick question and no disrespect toward you, but what are your goals with the cam swap and 1.8 ratio that I read on a different thread. I only ask this cause I don't want to see you spend good money and not achieve a goal.

I would say mild. That's just a stock cam for a 454mag-502mag mpi. Gen Vl. Exactly what 454 do you have? Sounds like that might be what you already have.

I agree, What is your speed or HP goal? What is your budget? Give the most detail posible up front to get the best responce.

That looks like the stock 454Mag EFI cam specs.
