LS6 vs Triple 12 I have a fox body running a gen IV 5.3 with 317 heads, LS6 cam, turbo 350 and 75mm/75mm turbo. I have a triple 12 cam sitting in the garage as well. Trying to decide if it's worth the time to install it vs leaving as is. Much difference in trap speed or pretty comparable? Also, much difference in lag from a roll?
Thanks.
Thanks.

Ls6 cam is a better cam over the stock cam up top but it lacks in the mid range. I couldnt be happier with the 3x12. It was a night and day difference over the stock lm7 cam in my 5.3. Bottom end and midrange are much stronger and it pulls like beast up top. Dyno testing showed 90hp under the curve and 50hp up top. This was on 2 psi less boost because I was running on just the spring.

Matt picked up 10 mph in the quarter on a stock 4.8 by doing nothing but adding a Triple 12. 10 mph in the quarter from just a cam swap on a car that's already running close to 130 is a huge jump, especially from such a small cam.

I know the cam's performance is in the right direction. Just trying to figure out if it is significant enough to bother with the swap vs trying something bigger. And I'm not complaining about the current lag, it's not bad all things considered. But I would like to know if it would be a significant difference with the triple 12.
No one has some trap speed data after this swap

243's are a waste IMO. You could work your 317's or even a set of 862's and they would blow the "as cast" 243 out of the water. 243's aren't worth the $450-500 they are going for used. Great head if you can pick it up cheap, but put that same money into a set of 317's and you'll be miles ahead.
Also gotta laugh at this... 64cc to a 71cc head drops compression about .8 by my calculator. So we aren't even talking a full point. A full point of compression is only worth about 3-4% of the NA HP. So if his 5.3 made 350 NA crank HP... (which I doubt) that's like 14 crank HP difference. Figure .8 you are talking like 10 crank hp or less. That's not going to be "lag heaven". If anything it will open up the tuning window and let him get away with a little more boost.
My 8.6:1 5.3 was great. Easily got up on boost on the line and went 8's with minimal effort... 60' great as well.

Back to the cam...I have not seen much talk about the 215/215/212 or the 218/218/212...anyone have real life results? Everything I have read says the Triple12 is fantastic.

Agreed that the better of the two is the triple 12. Next best question to keep this rolling in the right direction... do you guys think the isky 218 cam is too large for this setup, or would it be another step in the right direction?
I think there’s way too much emphasis and hype in cam selection. Trip 12 is great, I really liked mine… but a LJMS stg1 or tick stg1 would all work about as well IMO and be within 3-10whp of each other at slightly different RPM ranges I’d bet. Aftermarket cams pickup huge over the OEM stuff, but I think once you start debating cams within 10-20* of duration with similar valve events and lift… you’re splitting hairs.
The 215 and 218 grinds will move the power range up a hair over the 212. If you’re running a factory engine with a factory rev range a smaller cam usually compliments the factory parts better. If you start squeaking out more RPM with aftermarket intakes/heads/valve train etc… the larger duration stuff starts to shine. I’d grab any of the entry level cams and concentrate on the head ports with a good valve job. Should be an easy 75-125+ crank hp with a good valve job/port and cam over you’re current setup. Then double that gain for every 15-16lbs of boost you run. ( assuming your turbo system can keep up)
