I have a 4.5 stroke and a 4.75 stroke Callies crank but would like to build the 4.75. Both cranks have 2.200 journals. This will be a nitrous deal with a 2 speed 400 1.48 or a 1.58 glide with 315 pro drag radials. The heads are B1mc with a fogger flowed by Kevin Neil.

1. How large of a nitrous grid cam will fit in a standard cam location (already have) world cast iron block with a 4.75 stroke with 2.200 journals and steel Oliver rods?

2. Is the torque from the 4.75 over a 4.5 stroke worth the extra work?
Just wondering if it would make a difference from the 330' to the 1/8th?
