I have a ASP underdrive pully on my 98 T/A. With my cam install I am going to put in a Rollmaster Double Roller Timing Chain. To use my ASP do I have to machine it to fit??
wont know till its fully on and you see the clearance. mine cleared, others havent. supposedly pulley's machined after apr 03 dont have issues but thats debatable
I didn't have a problem with either one of my ASP pulley's (old style and new SFI approved one) with my double roller, nor did the 3 or 4 friends using the same setup.
