Debating about getting them for my 351windsor to get rid of the old steel pulleys. Obviouslt they look nicer but they also claim a small hp increase with the performance ratio, is it true? Are there any problems with them?

 

The use underdriven sizes to get more performance. They are a bit expensive if you just want the power, but the quality is spectacular, i had one on my 1970 torino for a while. They look great, and they clearcoat them so the aluminum doenst oxidize. If i could afford it i would use them on everything.
