Default worth it to change cams 231/237 to 233/239?

I currently have a tsp 231/237 cam on the lunati lobes and was wondering if it would be worthwhile to change to tsp's 233/239 cam on the more aggresive lobes. would the midrange i would gain from the different lobes make the swap worthwhile??Love the way the car runs with this cam, just getting bored and wanna try something new. Also thinking of maybe a g5x3? whadya guys think. The car is mainly just a weekend warrior, but it may make it to the track a few times next year after i get my new clutch and rearend in. So far the drivability of the 231/237 has not been a problem, just lookin for a little more get up and go.

Depends what you see as worthwhile. You will make up some power through the midrange and definitely up top but you will probably only be seeing somewhere around 5-7 HP to the tire. I can't see 2 degrees of duration netting you much more than that. I would look at some other bolt on's like and underdrive pulley if you don't have one and save the cam swap for something further down the road unless you currently have all the bolt on mods you are wanting to do. Let me know if we can help!

Those two cams are virtually identical except for the lobes. I would not change cams unless you went with something different than what you mentioned.

For example that 231/237 cam could be a 232/238 and the 233/239 could be a 232/238.

Normally Comp grinds are even numbers.

No. I've done swaps like this for people trying to get every little bit, and they've either gained nothing or lost power.

Recently I switched out (Won't name vendors) a 226/228 cam for a 230/232 cam. Car is a TEA headed, FAST intake car. Guess what it picked up.......Absolutely nothing. This includes a retune.

2/2 degrees isn't going to make any difference making the swap worthwhile.

Money may be better spent on heads, ie milling/porting, or some changeover 243/LS2 heads.

Cheers,

Macca

i am VERY happy with my 231/237 cam. Everyone tells me its "played out" and an old grind. That may be but, it took my 3750lb race weight, 6 speed, stock 853 heads TA to 12.02 @ 118.5 mph with a 1.9 60ft ....with a decent sized vaccum leak in my intake manifold.

Cool, thanks for the recomendations guys. I was not really worried about the duration numbers, but more the lobe profile. I just read alot about the lunati lobed cams giving up lots of low end as opposed to something that is ground on xer lobes. sounds like the difference wouldnt be worhtwhile though

Perfect answer here! gotta move atleast 4* to see a move, or just mess the LDA all up and see a change. LOL

For your application, if you are gonna change get the G5x3. It is supposed to have the COMP XE-R lobes, which will help you out a lot.

I got a 232/236 (pretty much the same as a 231/237) and I make over 450HP and 415 TQ and its still a nice street car. Its a good cam especially if you match your combo up right which is what modding is all about. Gotta match your parts rather than just putting all your eggs in one basket like big cam only.

I somewhat went through something like this.

I have the 228R and wanted to upgrade to the TV2 or a FAST 90/90 set up.

I asked the forum which would be best, and a couple quality guys suggested for the 10 RWHP differance Id gain with either, go with the 90/90 and lose nothing.

I did that and the car drives the same low end, and quicker through the RPM range with the 90/90. And I did the install myself

A friend did the same thing with the same year car and same set up, and gained about 15 RWHP with a Vengance ported 90/90 FAST set up.

Im still thinking about a larger cam, but the car gets used so little, and runs so good now, other than bordom, I shouldnt change........................but I will someday im sure.
