Matt actually, some of the blowers are compltly emissions legal.

Behold..................my 4 bolt main, 355 / 425hp SBC, 9lbs blower boost, 144 B&M Blower, Holley 700 cfm Double Pumper blower carb, 76cc chamber iron heads (I'd perfer aluminum Edelbrocks ), dished blower pistons, roller rockers, mild street cam, ceramic coated headers, etc.

When using a blower, you need to get your compression down, 7.5:1 - 8.5:1 no higher, your head chambers must be large 72 - 76 cc to achieve low compression. Intake ports 190 - 200 cc , to large a port and you'll get detonation.
Also a blower carb is a must, Holley makes a new 700cfm DblPumper blower carb, any bigger and it'd be to much carb for the application.

What size heads do you have on your 305 ? Can you put a blower on the intake manifold you got ?
