pulley question

[mclendon]

which would best a reduction set or a 1:1 set on a sbc turning 6500 to 7000? Thanks.

depends on the temp you are running. if youre running a little warmer than you want you might want to get a set of reduction pulleys or go to a double pass radiator or both. in our LM we run a set of 1:1 with a double pass and we stay right around the 190 mark most nights but it will start to get closer to 200-215 on the hottest nights when the track is really hooked up.

Usually a 20 percent under drive works well.
