I've had a G5-X2 (232/240 .595/.608 114) for over 2 years now. The car made 436 rwhp w/ boltons. It was great for HPDE use and weekend flogging, but not so much for mornings commuting to work in traffic and general around town parking lot duty etc. I have a findanza aluminum flywheel which exacerbates the problem.

So now... I'm considering some AFR 205's and a new cam... something that makes power from 3000-6500 rpms so I don't have to rev the car to 7k to take full advantage of the cam. Also want something that's easy on the valvetrain to quiet it down and increase spring life.

So... anyone else go for the big cam at first only to "mature" a bit and go with something different the 2nd time around?

Anyone think a 224/228 on a 112 would accomplish my goals?

I have done it each way. Went from bigger cam to smaller and vice versa.

While honestly it was more 'adrenaline-pumping' to go from a smaller cam to bigger, I totally understand your point.

I think it is always a highly personal and subjective interpretation on what constitutes a big cam and what is considered small.

To me it has always been about combination and what your goal is. I only went to a bigger cam went I moved to a higher elevation and needed to pick up my DCR.

The lure of power is addicting. To me AFR 205's and the 224/228 cam would be just fine. I think Tony recommends the 114 LSA.

There was a great thread a couple of years ago on how fast LS1's were running on just a 224 cam-only set-up. We spend a lot of money to get an additional 20-30HP, and if you end up losing traction with more power..you have to question it.

If I ever 'do it again' I will just go for more cubic inches and a smaller cam. Power, but not having to 'over-cam' it to get there.

Good luck with your project.

I'm going to see what Patrick G comes up with for this application.

i did with my 402. in my stock LS2 i had a 230/236, .600 lift 112lsa thunder racing cam. i liked it, but when i had my 402 built the first time i had a vengance vindicator put in there. i had problems with the motor, and only put down 460hp/440tq. the company tried to fix it, and then the power went down some more (cause the company SUCKS).

when CMS rebuilt it recently, they put in a 232/236 cam i believe, something around those specs. it put down 465/462 on the same dyno, but the torque curve is better than before, and it drives a lot better with the current converter. im happy with it, and the car pulls whever the RPMs are

This is my line of thinking too, my 383 with a mild cam runs just great for me!

I went from a MS3 to a xfi lobe 230/236 and gained everywhere except a couple peak HP. The down low torque gained from the swap was pretty extreme like 25+ from 2500-4500 and stayed above it all the way to redline.

^ That's exactly what I'm wanting.

Hey Brian,

I ran a 230-236 XE-R 112 +2 in my 346 and loved it. I drove it everywhere - DC rush hour, long trips, Cross Bronx Expressway in rush hour with the AC on and now problems. I could have driven it everyday. Full H/C 90/90 setup made 460 very usable HP and peaked around 6400. With the newer lobes available you could probably go smaller than that and still make great average power.

I run a very small 22x/23x cam in the 403 and you've heard how that drives and still makes 520+ but max grunt. You don't have to give up a ton of peak HP to gain big on the bottom and middle.

PM sent.
