Cams for this setup..
Hello.
This is the engine.
l98 block
eagle 4130 steel crank
5140 steel rods
KB hyperutectic pistons
10.3 comp
113 ported heads with bigger vavles 2.02
headers
MINIRAM
Im looking at GTP 6 cam
235 int
242 ext
cam lift
.568"
.592"
with 1.6rrs
To big?
I must pass sniffer test in Sweden, I gues its a bit less demanding then in the US.
Thanks

Re: Cams for this setup.. (devilfish)
Hmm it depends on how much less demanding your countrys test standards are. Thats a pretty big cam you got there. What are the flow numbers for your ported heads. With a cam that big you are going to want a lot of flow, and the power curver is going to be up there. I would suspect that with a those numbers your RPM/Hp curve is going to peak around 6000+ RPM. Is this going to be a daily driver as well? It also makes a difference what the lobe separation angle of that cam is, it maybe a bit more acceptable if the LSA is 114 or so. But being thats a GTP grind I would suspect its more like 112 or maybe even 110 degrees.
Just my two bits worth of thoughts here.

thank you, now not really i dayli driver. A weekend warrior.
6000rpm is OK not abow.
I sugested a hotcam, but I think its to small for that setup.
A set of better heads is going on later this summer. So we build for the future.
Thanks

hi...
A guy at thirdgen (Traxion...350cui miniram ..) ran 12.2 with CC08-502-8 cam 218/224 0.495/.502 . He went with a bigger cam after that 230/245, but I think it would be too large.
Several goes with the cc XE 224/230 0.503/0.510 112 lobe..
Call me some evening and I can look at several combos in desktop dyno 2003.

I have that same basic short block and heads you are thinking of, along with headers and Miniram. I am running the ZZ9 cam which has power to about 6300RPM. with the longer intake duration of that GTP you will be shifting the power band up to a higher RPM range
