The saying "been there done that spent a cubic ton of money to get there" comes to mind

agree......that cam will nose over well before 7000 with that cubic inch.......i ran an AI 234/242 in my 355 back in the day and it peaked at 6800 i shifted it where the computer crapped out.......be supprised how well those heads will work on a 383 even with the smaller runners........

I have LE2 h/c/i with a ARP'd 350 all stock parts. Have no regrets. And it's a daily driver.

I like people who put x's in their future cam specs and ask for opinions on it.

Why? What's wrong with a hydraulic xxx/xxx cam? It should put up pretty good power numbers. In the range of xxx rwhp/ xxx rwtq. No?

I think I'm going to add that to my sig. lol

Yes, I've done it successfully. 3 years beating on it and still going strong.
All stock rotating assembly. Honed the bores back to round, resized big ends with ARP bolts.
If your x's above mean 0's, then I agree with what others are saying that it's not enough for a stroker. HOWEVER, for a 350, and if going for track performance rather than a peak dyno number, a 230 cam is as much as I'd run with the stock PCM. The heads are great and don't need to be crutched with more cam than that. I'm running AI's 228/234, .61x lift cam in mine and using the PCM limit for best ET's. Sure it peaks at 6400, but it holds the power all the way to 7100, still more than what it has at 5400 where it drops after the shifts. I'm running a 4200 converter. If you're running more than that, then you can handle slightly more cam since it won't drop as low on the shifts.

Nothing wrong with running over 240 on a stock pcm.

Only two reasons to do that with a 350:
1. crap heads
2. dyno glory

Ok, maybe "crap" is too harsh. But comparing to the AI 200cc's that he intends to use, out of the box Trickflows ARE a lesser head.
I'm trapping 120 in good Midwest air and 122 over in your neck of the woods with my little 228 cam at 3800 lbs
What converter were you running then, Mike?

I would be very happy to trap 120+ , and eventually hit a 10. Keep in mind I'm m6, 10s for me won't be easy , but those are my goals.

If you actually want to drive your car anywhere other than the track keep your M6. But if you just want to be a 1/4 mile queen go auto.

I trapped 120 with my setup and my car is anything but setup for the strip. That's back when I had 3.73's and I was crossing the traps at under 6k. I was short shifting at 6500 too when this cam pulls strong to 7k. There's no reason a h/c car should be trapping under 120 these days, and low-mid 120's should be pretty easy with the proper setup.

I doubt I'll ever feel like rebuilding my rear end again, but if I do it would be interesting to see what the 4.10's and lid did. They definitely woke it up on the street.

What was your setup ? Still on the 10 bolt? I've heard of h/c guys picking up a few mph switching to a lid.

No sense worrying about it. If that's what you already have, make the most of it. Shift it as high as you can. It should want to rev to the moon with those heads.
