Hey is that a sag' steering pump? What block have you got it bolted onto, and how hard is it to get it to fit? I hear it is a straight bolt-up for 302s, but 351s require a bracket. But you have a 429 right?
Maybe I can show you what 420 rwhp feel like @ 10 psi. Quite possibly if it's a few months down the road it'll be pushing 500+ rwhp. Not too shabby for a little 306 mr.429
