Have already verified plenty of clearance at max valve lift.


The intake valve is usually closest to the piston at around 10ATDC during the intake opening.

With the intake valve at full lift, the crank is at around 113ATDC(in your case ...... which has the piston about 3" away).

On a different train of thought...... What are the lobe numbers for that cam?

I'm trying to think of a combo like yours where I'd feel a 115lsa would be the preferred choice.......
