even though I'm going to be doing the six speed swap first I'm trying to gather as much info as possible before I end up doing a heads and cam swap on my car.

my current cam with ported L98's aint cuttin it. I will be running the Dart Pro 1 aluminum 200cc heads, 2.02/1.60 valves with 64cc to try and up my compression a tad. I already have the Holley Stealth Ram on it now and I will be running that on the next set up as well

So i was wondering what cam woiuld be the best choice for those heads? It would have to be a retro roller set up so id be buying new roller lifters and pushrods as well with probably 1.5 rockers but I havent decided yet, any input or suggestions would be great!

 

The Dart heads have a similar E/I flow ratio to stock heads, and so will benefit from a cam with some split toward the exhaust.

I'd suggest the Comp XR276HR, or the XR282HR if you're good at tuning. I'd recommend getting the 1.55" spring option on those heads, and running 1.6 rockers; they can take advantage of the extra lift. If you're willing to go the custom cam route, look at getting them to grind you one with the 3194 intake lobe and 3196 exhaust lobe, on 112° centers. If you do that it will have enough lift that you'll probably want to stick with 1.5 rockers. A "rev kit" will help.

 

Are you doing the cam swap before or after the transmission swap? Either of the cams RB suggested will need a higher stall, something like 2000+ i believe. Just something to keep in mind.

 

since you're buying the lifters anyway, why not go all out and get a solid roller?

 

200cc Runners is pretty stout for a street head. And Dart is an excelent choice. I preferably would run an Xtreme Energy setup from Comp. Like the XE274 with a 1.6 ratio or step up to a XE282 with a 1.5 ratio. Either or should keep the heads flowing where they need to be. But sense a 200cc head is a little more about topend rather than lowend go with a Lunati cam. Expiensive but they have the cam that will probably run with that head best. I dont totally remember the specs but its something like 292 dur: and a single pattern 480" lift. The cam's a rever but I think it would best suit the heads.

 

nope the six speed will already be in by them time i get to doing this I already thought of that, if id plan on going with that set up id get a 2400-2800 stall....with the cam i got right now i should be running a 2000+ stall but i figured i wanna save money to put the 6 speed in so i didnt see any sense in duming money into my what i had now.....


thanks for the suggestions guys i probabably wont be doing all this till fall but im jus trying to gather as much info as i possible can before I jump into it.

 

The later cam you mention is the Lunati Bracket Master II cam, i beleive it is grind number 00010 or something like that. Yes it does have more advertised duration, however, when comparing cams, you use the .050" duration figures. And by looking at them, the XE cam has a 230/236 @ .050" duration whereas the Lunati has 230/230 with less lift. Then, comparing the .050" duration to the advertised duration you can see the Xtreme Energy cam has quicker ramp rates. And as you know, quicker ramp rates means more time is spent in the 'effective valve lift' range. That means more power. So, in essense, the Xtreme Energy cam is still a tad hotter. It also has a slightly larger RPM range (1800-6000) versus the Lunati's (2000-6000). I would take the Comp over that particular Lunati.

 

on the flip side, the Lunati cams less agressive ramp rate is kinder to your valvetrain, offering longer life for a street driven car.

athough id still go with more duration and lift.

 

ya im liking the XR282HR cam....plus i get get a chip burned for a certain set up so tuning would not be an issue.....appreciate all the help more suggestions of course are welcome!
