its "ok" if you don't want to go too far. Some of the hierarchy in the cam world will chime in im sure.
Id say Its a touch "small" for a cam in general especially for the 6.0. unless you have to deal with smog in certain areas id get a slightly larger cam. It would be a slight wakeup from stock, but I don't think all that work would be worth such a small cam. Id start at at least with 224ish cam.
For sure, get with Martin from Tick to get a recommendation on you setup and what you want out of it. he gave me a size I didn't even consider for my own rear mount turbo set of 226/235 114 cam with my car being a street driven car with a relitivly stock 5.7L.

I agree you would benefit greatly from a bigger cam speced for your exact needs. I would probably do that cam in a 5.3 but not a 6.0.

Tick stage 1 or 2 turbo cams or customs...that cam will certainly fill better than stock and make more power but there's more power to be made with one of the cams I said

Ya go bigger, stock48's car is slow with it's little 218/218 cam. Fun street car?? What are you goals for the car? Is it ever going to see the track? How fast do you want to go? Are you concerned with fuel mileage, spool etc? Bigger isn't always better. I haven't been to the track in over a year. My truck caught fire and I replaced it with a Ford Escape so no more pulling a trailer. I went from a "custom" cam back to the stock L33 cam and I fell in love with the car again. It idles better, is quiter and makes way more low end torque. Yes I'm sure it's slower at the track but I don't really care at this point. I could just give it a pound or two of boost and be right back where I was before. Plus I'm getting close to 30mpg out of it on the highway at 65mph with a th400 and 3.08 gears.

I say its a great cam for what your trying to do, but advance it a few degrees if it isnt already ground with some advance.
I'd change the rear gear to a 3.73. Dont listen to automatic guys tell you to gear it tall, that doest work the best with a stick shift.

That cam will work great, so will plenty other cams but its about what you want.

Ive got a set of 410 gears, do you think that's to much gear.

Lol, end of thread. No more needs to be said.

Depends on tire size, shift rpm and how fast it goes through the traps

stevieturbo

If he makes any power at all...which he should, then 3.73 will go up in tyre smoke.

Mine's a YSI, and Ive tried 3.55 and 3.27

3.55 is slightly better on the street for normal driving, but overall the 3.27 is better..3.55 would be ok if your motor spins to over 7k with ease though.
The 3.27 definitely helps with traction.

I wouldnt even consider going shorter than 3.55 though.

I disagree. If the car is never going to the track , fine gear it tall, but even if you want to just take it to the 1/4 occasionally, you need to gear accordingly.
If tire size, shift rpm(and peak power rpm), and either hp, or trap speed are known, the best gearing can be figured out.
Slicks will solve tire spin at the track
Tall gearing in a stick shift just kills clutches, or slows the car down, from my experience - you can get away with it with an auto trans, but not a stick

stevieturbo

With the 3.55 and 26" tyre, I was at 149mph at basically 7k in 4th gear
3.55 was too short for me.

But yes taller gearing will be harder on launch for clutch. I've swapped a couple of times between the 3.27 and 3.55. I'm on 3.27 now. And not a chance I'll be going back. The car is slower with the shorter gearing.

If I had 7500-8000rpm available, then I'd defo reconsider that though.

Now we are getting somewhere , the gear chosen depends on the math. If your shift rpm was 7k, you would have been geared right. I take it your engine is past it's shift point at 7k?
I'd like to hear the details about the OP's combo and see what the math says.

Oh man, math is like a dark art around here. Not a lot of people are friendly with that!

stevieturbo

It does shift well at 7k, but it isn't ideal that high. Let's face it, not that many push beyond 7k.

But absolutely, more details are needed. Especially expected power and torque, and expected shift points.

IMO, the more power you have, rarely is taller gearing a bad thing. Especially on the street or any other severely traction limited scenarios.
