help Super Charger Small Block

I agree with other posters here. Given the efficiency of today's blowers, and the ability to 'slow down' the blower to reduce heat while making good boost is the way to go.

A 4-71 would be a good fit for a V-6; 6-71's for most small blocks; 8-10-71's for big inch race small block and big blocks; and 10-12-71's for big inch big blocks and large race big blocks.

Just my .02
