While i love my 6 they arent axactly sporty without some work. I know Clifford Research sells 4-bbl and triple Weber conversions, as well as hot cams for sixes, but all I put on my 232 cid Gremlin X were a set of Hooker headers. They had two collecters: Numbers one, three and five cylinders went into one, and two, four and six into the other. A set of glass pack header mufflers and two very short pipes with chrome tips exited out the side behind the driver's door. Believe it or not, that thing MOVED. Now, I know some of you are thinking I'm some kid who grew up on Civics and Nissans, so I really don't know what performance is. Actually I'm 44, and I've owned three Javelins (two SST's and one AMX), as well as a 360 powered 1970 Ambassador SST (two door, of course). My father got me started, as he bought a 1969 Javelin (290) at the ripe old age of 39, and followed that with a 1970 Rebel MACHINE, and a 1974 Matador X Coupe (401 4bbl). The Matador was his last performance car until he bought himself a present for his 70th birthday last September: a fully restored and detailed 1968 AMX! But I digress....If you doubt that six in a row can go, consider this. About ten years ago, a guy was racing a 1969 Javelin at the local stock car track in my Dad's hometown. He was running a 232 with cam, headers and 4 bbl - the ONLY non-V8 car on the track. He did quite well, often finishing in the top five. Did I mention how much the Chevy boys hated him? Made their pro-built 350's look a littl silly. And that sound....close your eyes and you would have thought it was an Indy car - very bizarre.
