just some random thoughts:
1. rear end gearing?
2. Why not measure the current cam and figure out what it is? (save a lil cash to be put somewhere else.
3. Search the local craigslist for parts.... I recently bought a nearly perfect F427 intake for $75. I like them on a truck, I probably would have gone with something else, but what can a guy get for $75? You can probably sell the StreetMaster for $150+ so thats helpful too. Also got a 1.75inch primary 3inch collector headers for $50 brand new.
4. anyone that paints an engine block green and heads a fake aluminum..... well crap, I dunno what to say about that.
