What do you guys think of pullies on 4v's?? Thinking about getting a set but heard there a hit and miss and not worth it on cobras? What are your guesses opinions? Who makes the best quality ones?

Be VERY careful with pullies on a 4 valver. Some may set up a weird harmonic down the crankshaft that may lead to oil pump going boom. Myself, rather than getting pullies that you'll only see about 5 hp with, is install an electric water pump. They're good for about 10-15 hp.

Pullies are perfectly safe on a 4V if installed properly. I had my crank pulley on for 60k+ miles and recently added the water pump and alternator underdrives. I would reccomend doing all 3. I am using the Summit 4.6 dohc pulleys.
