Will this 248/250 612/615 113+3 cam be too hard to tune in a big stalled auto car ? What does the 113=3 actually do for the cam and what does it mean? Thanks Brian

 

the cam should be good for a 402. you could even go a bit bigger IMO. the 113+3 means that the cam is on a 113lsa with 3 degrees advance ground into it. i have no problems driving a G5X3 on a 112 in my 346 automatic so tuning shouldn't be a problem

 

Sounds good, thanks!
