With 1200 miles and constant seat of the pants fiddling with my stone age Calmap 6.2 software my 383 is usable and enjoyable to drive.
Smooth (well almost) idle around 1000 rpm-
Brakes are fine-
Will cruise around town close to 2000 rpm-
Great response at almost any rpm-
Hints of copious ponies- I will have to do high load, high rpm with a good A/F meter on a dyno. I ran it up in 4th (going uphill) yesterday, not quite smooth. Too many snakes on that trail to do it seat of the pants.

 

Cool!
That is the cam I picked with my 383!
My engine is not together yet, though.

Keep me updated if you take it to the track.

 

I'll update, after I go to the dyno and get the top end sorted out.

 

Sounds good. The 280XFI is what I'm thinking about putting in my 383, AFR 195cc, 10.7 compression, and Stealthram. But, I will be going with 1.52 rockers instead of the 1.6s. Just need something reliable, not all that radical, dependable and will get me around. Also thinking about a custom 224/230 XFI cam as well....not really sure.

 

Just for reference here is the XFI-268 at idle, (picture quality sucks) idle is nice on a 1.6 rocker, 383
I have a new XFI-292 on the shelf waiting to go in the new 383 for the IROC and I'm selling the CC306 that was new, some time when I get the paint done...

When are you supposed to go to the dyno?

 

ST-
I'd go with the XFI 268 with 1.6 rockers for what you want. I think it will scream when you want it and be totally tractable. I went with the 280 cam because I've got these 210 cc Dart heads.
I never got much going using 1.6s on cams designed for 1.5s. I bet it works the other way too.

Gixx-
Dyno is sometime...... my racecar (roundy, round with a 1043cc GSXR 1000)gets first dibs on my attention. After I put together this friend's FZR 1000 (a puzzle), then I'll treat my baby to a dyno tune. Sorry it's not sooner.
PS-I have the fizzer on my work bench- finally!

 

Thanks for the heads up. I was really looking at a custom 224/230 XFI lobes anyway or the XE 230/236 on a .503/.510 lift.

 

If you are going custom you might want to look into the LSK lobes by Comp Cams. Thunder Racing can hook you up. The XFI lobes are also very good.

 

Very true....just didn't think the LSK lobes will work on the GEN I engines for some reason.....I'll start another thread on this one.
