Looks small to me, what are the A/R numbers is it a t4 or t3 flange how big is the inlet on the compressor? if it is for a 6 BMW it wont be big enough for much power. Go with t70 or something close to that size they make enough power to split your stock block ( you can dial it back) and it should work fine on a 302 and give you some room to grow. Master power make a good turbo T70 for a good price around 550 or so and thats new. IMO
im going to go turbo here probably around xmas time or a bit after, i would check out this companies turbo setup it seems pretty good. http://www.turbotimepsi.com or someone added this kit which is 2000 bucks more but looks pretty bad ass. http://www.hellionpowersystems.com/customer_rides.php
