Re: to ALUMINUM or NOT (intake)
I realize you are probably trying to save some $$$ by using what you already have. There is a reason why you never see a stock intake on any kind of a performance motor. It's really hard to beat a Performer RPM intake. I just sold a really nice one on eBay for $50. They will usually go for that up to about $75 for a super nice one. An aftermarker intake is almost ALWAYS the first true "bolt on" upgrade you do to any motor. Thanks to our friends at GM, and the good old SBC, there are about one gazzillain of these out there floating around.
