1971 Chevy Vega front pulley system At this point I have a smaller alternator and pulley set up system on front of car but it seems like the pulley are not big enough and probably water pump and fan are running slower temperature is going up to 210 to 220 was told probably needed larger pulley what front set up system are you guys using

In your picture I see you're actually under driving your water pump since your crank pulley is smaller than the water pump pulley. I cant speak for everyone but I think a Monza V8 pulley setup is pretty desirable because it overdrives the water pump. I'm using an 75' corvette 6-3/4 crank pulley with an oem water pump pulley off ebay that's about 5-5/8 and have no issues for a street car with a partially filled block. I have also tried the ebay aluminum 1:1 pulleys and they did not work well for me either. Maybe someone else who has experience with a motor plate can chime in but I suggest trying to get a smaller water pump pulley and a larger crank pulley from the setup you already have, looks pretty slick.
