[QUOTE]Originally posted by AaronC: [QB] [QUOTE]Originally posted by PunkINa5.SLOW: [/qb][/QUOTE]I argree for smog but I dont like same lift on exhaust sas on the intake i like to see more lift/duration on the exhaust side on SB dorfs[/QB][/QUOTE] It's really going to depend on the heads and induction setup and the whole combo that will determine what cam would be best. Lately I've been seeing several reversed split cams on the corral and Camara90 has one and so do I on my 306. His car runs like an animal for a street 347 since his upgrade to 185's and the custom cam. I got my 306 running last night and even with some tuning problems this thing is gonna be a RUNNER for a street 306 (112-115 mph NA in a drop top). My cam specs look like this 224/222 .555/.528 111 LSA and 274/272 at .006. Mike's are 232/228, .565/.538, 110 LSA 282/278 at .006. It's an interesting concept but our cam grinder says it's what makes these long runner efi motors run. He also likes a late intake closing point because of the long runners. On most aftermarket cams like the TFS #1 he strongly recommends that you retard it to a 115 Intake Centerline and put 1.7 rockers on the INTAKE ONLY. He says the hefty exhaust bias is not needed in most applications. So far I'd say this stuff is working pretty damn well. He's been accurate as to Mike's car and from what I can tell so far, mine too. They're also starting to do reverse split cams on LS1's with LOT's of success. [/QB][/QUOTE]
