I have a 94 cobra with dss 306 with trickflow H/C/I. I also have a v2 s trim. The last time I had it dynoed it was 502 rwhp with 11 psi on the stock plley and power pipe. I am wondering if I could throw a 3.00 pulley on there or possibly meth injection to gain some more power. I do think that I am living on borrowed time with the block though. It does have a main support girdle on it. I know that the meth injection will help cool things off but will it give me as much gain as a smaller pulley.
