I did not know a Holley would not work on your intake

I would think about a intake change as well. I know $$$ is hard to come up with nowdays,but it sounds like you may have to much $$$ in it already to lose HP with a stock intake & carbs. Or maybe some of the NSS guys on here could help you out.

I don't know much about Hemi's but I got $$$ that says my Wedge engine will out-run them fords.
