Driving a Big Cam/Stall - Opinions?

XXX Motorsports has done alot with fords, i dont know much about them with GM tho
get a break in tune from frost if you want and then if you dont want to use XXX for a dyno tune shoot me a PM and ill tell you who to use and who not to in the FL area

Everyone who errrs on the tad conservative side of camshaft selection ends
up having a great performing combination and then wishes they had gone
bigger. Those who go Donkey Dick with stock compression end up wishing
they had gone smaller. Your 11plus compression does help alot but I'd still
go with the smaller cam and enjoy more average torque rather than go for
all out top end. I'd say a 383 stroker or a 402 would love the larger cam
because the 4" stroke will still have the torque to be street friendly.

what are you going to use the car for? get a cam that will make the power in the rpms where the car will be driven
i had a cam in my car that you had to spin the **** out of just to make TQ and i ****** hated it

Big cams fit my driving style. I wind the **** out of my engines. There is nothing like the feeling of going 75mph and stomping it and having the car launch like it was leaving the lights. Around town is a little rough, and the torque might come in about the time most stock engines make peak horsepower but the sheer brutality of a cam thats too big in a car thats too loud is just right for me. It might not be the IDEAL combo but **** it. We aint racing for points in the NHRA are we?

I just put this in the drag racing tech, but wanted to present it here as well:
https://ls1tech.com/forums/drag-raci...-me-1-4-a.html
Given that I could probably live with either one, which of the setups am I looking at would be faster with the stock rearend/tire combo I have now? I don't want to change or have the budget to completely gut the car and do it however I want, so that's part of it.
I know that was brought up that the bigger cam wouldn't be at an optimal RPM in 3rd gear going through the traps. That's the kind of great insight I could use.
Thanks

I've had several setups - all sorts of various parts mixed together at different times.
From hand ported unmilled 241s to CNC ported heavily milled 862s.
From a 221/221 cam, to a Futral F13 to the MS4.
Stock compression to 11.6:1
Stock converter to Art Carr 3600 to Yank PT4000
LS6 intake to ported FAST 92
4.10 to 3.73 gears
The big cam big converter setup is by FAR the best overall, even part throttle low speed drivability. The only downsides are the poor fuel economy around town (highway is still mid 20s!) and the complete lack of stealth. It draws a lot of attention, mostly unwanted. But I do admit the comments I get from clueless import guys are amusing.
Most of the people complaining about big cams are running stock compression and gearing on a junk tune - ignore them.
Finally, you may not see a big performance difference going from a stock 3.23 to a 3.73 ratio, but the drivability will improve significantly, taming both the cam and converter in regular driving.

Thanks, Marc. That's good to hear.
I am planning the setup to run a big cam... so going smaller (albiet a 231/238 isn't exactly small) just doesn't seem like the best way to maximize the investment in the other parts.
I also spent some time listening to TSP True Duals... So I might end up with a huge cam, stall, and dumped duals and completely change the car (the true duals help a lot with that sort of overlap). And that's good to hear on the 3.73s. I just worry a 4000 stall with 2.48 STR and 3.73s will blow 315 DRs off on the street lol.

I would do the big stall for sure, I DD a 4500 2.4 str when boltons, but when I did the H/C it turned into a 5500. I had it changed to a 3800 1.8str and liked it much better on the street, and from a roll it pulled harder up top.
Now im going back to a 5000 or so 2.2str
The big cam is allot of fun, had everything in my sig on my stock shortblock last year, it was a bear to drive at times but totally worth it to see the looks on peoples faces. You are gonna need to go with 3.90 gears to enjoy a big cam IMO.

Compare the specs of the cams he used to what you are looking at before just trusting the description of "big". Look at more than lift and duration too.
Tighter LSA will usually compromise idle quality but makes more torque.
He also said 3.73-4.10 gears not 3.23.
Read all of what is said, don't just look for support for what you want.
I am also not seeing a lot of results in signatures.
Years back I met a local kid with a Z28 with a "big" for an LT1 cam that was like 232/236 and lift up in the .590s. M6 4.10s.
At the time my car was 208/221 cam with .474/.510 lift 2800 stall and 3.42s. He LOVED his big cam, at the track he beat me BUT my bumper was at the back edge of his fender or maybe mid door. Lost touch with him, pretty sure he got tired of the bad manners and lost interest in the car.

And I've also been thinking about the exhaust. The TSP 1-7/8" Headers and Y-Pipe look like a great bang for the buck setup. I'll just keep my stock WS6 exhaust and put a QTP 3" cutout on there whenever I need more sound or a little more power. Cheaper too.
I'll let you guys know the numbers and how she runs.

Jacob,
With anything you choose that I have given you insight on, I think you will be very happy with either way.
I really like the "in between" we discussed which would be the 234/242 112+4 or 235/242 112+4. Best of both worlds and with Greg doing the converter I wouldn't worry about drivability in the least.
If you did the V.2 Polluter I would highly recommend you fly-cut with your plans for the cylinder heads.
As Brian told you, 61cc chamber, 235 LSL intake lobe and 109ICL no clearance issues.

Thanks, Martin. You've been great.
And you're right, the 235/242 combo will be sweet with the 4000 stall and Tooley ported LS6 heads. I've asked him if he has any tricks for maybe 60 or 59cc with stock gaskets, but I know lots of shops have run 236 XE-R lobes with 61cc TFS 215s and had great results.
