Okay info. is coming soon....
Yes my 185 pulley was originally on Jerrys personal car before he went to the 191 pulley so it has alot of miles on it.
AND never has had a problem...as for dates hard to remember but mileage is real close to spot on.

Put 4000 miles on it stock.
Then was DYNO'd and tuned by LET
Put on a 1000 miles
Then put on Needswings CAI
Put on about a 1000 miles
Then changed plugs.heat exchanger

Put on 185 pulley and was tuned by LET
