I already got the Holley off my white stang, I was going to install the 185's off of it too but i need to notch the pistons. I don't have the time/money for a job that involed now. (the rings/ head gaskets/ bearings are finished on the white car). I sold it to someone who needed a project. I was going to get the 165's but the trickflow heads flow just as much, and allow 2.02 valves with high lift cams, and are $300 cheaper.
I have 3:73's in the green stang now and full length headers. I think i will go with the bigger C&L. I have heard of some noticable gains with the C&L units. And yes that is the stage 2 trickflow.
Do you have that web address?
hope to be showing you my tailights soon,
