Cam too big for a blower motor??? I am in the process of building an Iron Block 427.
I have to decide on final compression ratio
I also have to decide if my current cam is too large..
It is 605/238, 610/242, 115 LSA, installed at 111.5 CL
Any thoughts on this cam , and compression ratio..
I will be starting at 8psi with plans to go to 12-15 afterwards..
TIA

Re: Cam too big for a blower motor??? The cam is definitely too big...
As for compression ratio, I wouldn't do anything over 9.5:1 Just my opinion though... hope I helped! Good luck with everything.

Re: Cam too big for a blower motor??? Before deciding if a cam is too big, you need to ask yourself how much power you want to make and what you want to spin the motor to. There is no way in hell you can say off the wall that a cam is too big if you have no clue as to what he is wanting to do with it.
My .03 cents
99TA..7.2@95NA
85GT..331/106mm turbo in the works

Re: Cam too big for a blower motor??? To get a 427 you'll have to go .060 over on the block and you're going to put even more stress on the walls with a 4.125 stroke crank. I'm just thinking durability but it all depends on what you want. Like everyone said we need more info.

Re: Cam too big for a blower motor??? Don't take it past 422. Unless you sleeve it, I agree with phenyxTA's comments.
If you build the motor to spin high RPM's and have plenty of stall or will launch at high RPMs on an M6, the cam may not be too big... particularly with the amount of torque the big-cube motor will give you. With the torque it could have, who cares if the cam is big... as long as the motor can handle high RPM's.
I agree with those who ask for more info. Too much you left unsaid.
Also, you may need a bigger blower than a D-1SC or equivalent to take advantage of the RPM range. And MAN are you going to need some fuel! A Turbo may be better for you, as well.
