231/237 still a decent cam? I am still in the process of tuning and getting this thing tweaked, but I see so many people talking about FMS cams and G5X's and no one mentions the 231/237 any more. Is this cam that outdated?
it wasn't designed to make big numbers like these other cams so not many people want it anymore...it was designed to be big and easy on springs...it has very soft lobes

I had it in my car. Made great peak power, waaaaay up there in the rev range. It broke the 460rwhp mark with some TEA 1.5's, 90/90 and QTP HVM LT's. It seemed like the more you let it breathe, the more it would give you back. It kept giving and giving. It's your typical max effort cam.
Easy on springs, lopes hard. Still has its place I'd say. Great cam. The newer grinds provide just as much peak, with more meat under the curve, across the rev range however.

It wasn't desinged to make big numbers? I disagree. The more breathing room I threw at this cam (heads, 90/90, QTP HVM LT's), the more it gave. 460+rwhp ain't too shabby.

The 231 is outdated, even the TSP reps on here agree.

Edit: I will admit it's an outdated cam.
But so are so many other good cams. Last edited by SouthFL.02.SS; May 19, 2005 at 01:00 PM.

oh well at least it's not going to cost anything 
The cam itself consistently adds 50 RWHP. Yes the lobes aren't as aggressive as an XER lobe or most of the lobe profiles out today. The cam was designed about 2 years when there weren't any springs to support the big lifts and aggressive profiles out today. The cam is still a good cam and makes good power. With a good tune the cam should drive fine. I had this cam in my car for about a year and a half driving both in town and on the highway every day! By the way, the cam loves nitrous!
black_ws6: What bolt ons do you have on the car? What was the weather like? All those things play into figuring if you are trapping the right e.t. and MPH. I wouldn't think the cam alone is to blame for the low MPH.

This was good for 12.7x's @ 111-113 MPH on street tires
I have added: 231/237 cam, Comp 918's, Ported TB, MT Street Radials and a different tune that I believe was not too good. I still need to go to the track to see for sure, but I couldn't break the tires loose from a 1st gear roll at about 10 MPH with the original tune I loaded this winter. Now I can blister the tires from a 10-15 MPH roll in first with the new tune I am working on.
The day I went to the track weather was decent, sunny and about 70.

BTW, I may have a bad O2 sensor that is causing the car to stay in open loop. I am going to try to get that taken care of before we try to tune it.
