Need advice.
Back in the early to mid 80's as teen I had a 318 2 bbl Demon.. I bought a SB 4 bbl intake and carb, slapped it on and went.. Pretty sure it was a 340 intake, but for all I know, and knew back then it could've been a 360 intake.. I don't know. My point is, now I see where "things" should be matched up.. Are there rules, specifications that should be followed. I have another 318 2 bbl Demon and want to go with a 4 bbl, but want to make sure I buy the right intake...and carb. Engine is a 73 replacement warranty block, at least that's what I was told when I bought it..and is stock.Does have one orange head..??
