On a 340 cu inch, or any small block mopar, how big of cam can be installed before dot to dot on the timing gears is either advanced or retarded. TOTALLY CLUELESS I AM!
If you are worried about it being advanced or retarded, you really should degree it..or have someone help you do so. Thats the best way to get the most out of your new bump stick. but as mentioned, dot to dot 'should be okay', but not optimal likely
