at least for “burly” engines there is only ONE shop in the area that know the new generation engines, and that would be mcquillens out in leroy, ny. all these other shops are good at the old school engines, but there knowledge and experience on the new stuff is weak. there are alota shops that claim they know what they are doing, but their operation is shitty.
then there are guys on here that dont know what they are talking about but are big name-droppers, so they make people think they know what they are talking about…lol
for 4 bangers, can say i know the market for machine shops.
