Thanks for replying. I am sorry if I may be repeating stuff that has been hashed out before. But suppose every doctor only treated each type of patient only once and then expected everybody else to just read all his posts and find out how to cure their ills? Now my head is spinning. Also a couple things I said were in error. My heads have 72 degree mounting bolts but 75 cc chambers. Also my cam is CC Nitrous cam grind with 224/236 instead of 237/236. My lift numbers are .502/.520 on a 113 lsa however. So please let me ask this question: With the 195 Eliminators, I was told that they flow excellent on the exhaust side so my duration split would probably be unnecessary. Now since the cam does have a wider lsa and less duration than some cams listed here, can I assume that unnecessary does not mean detrimental? Well I do want the cam to work well on the street. BUT, if I ever do decide to fool around with Nitrous, this will probably be the only engine I may get a chance to do that. So has anyone here used a 383, 195 eliminator heads and this or a similar cam. I have had this car in my garage since 1995 only taking it out to wash it. The 305 tpi it came with was able to do 15 second 1340 times. I have the time slips to prove it! I have posted several times in the last couple days. The nitrous cam to me seems to be a real purpose built street/strip cam. Namely wouldn't it be better on the street (with 383 and 195s between 9 and 10:1 compression) than most cams, and better on the track (especially with nitrous) than most cams. I am willing to sacrifice high rpm performance over 6000 because I literally did not build the motor with it intended to rev far past 6000. I like it's 113 lsa cam timing for sound, driveability and brake ability. I don't want an obnoxious idle. So, I have tri-y headers and I need to find a quiet muffler ( no flow master no way no how). I really don't want it to rattle dishes inside the house. What I want it to sound like is HEY! somebody is trying to sneak a really fast car down the street. Which way did he go? Who? That car! Never mind... Gone...
Hasn't someone used the nitrous cam? Swapped it out? Swapped it in?
Should I use 1.6 rockers? All, or just the intakes? Would More intake lift cause problems here or could it maybe work to make the cam more normally aspirated leaning than nitrous leaning? Which muffler?
