Turbo Cam options
I did a random pull from a couple companies. This is a street/stip car with a ~3500 stall converter. Shooting for ~850 wheel.
My prev cam that used vvt. made great power, idle and drove like stock. was a dog off the line. .632/.630 221 228 116 -7.5 over lap Cam motion #1 .621/.612 220 226 114 -5 over lap rec stall = stock #2 .621/.612 224 230 115 -3 over lap rec stall = stock - 2800 #3 .630/.621 227 233 115 0 over lap rec stall = 2800-3200 #4 .639/.621 232 237 115 4.5 over lap rec stall = 3200-3800 *possible ptv clearance issue GPI #5 .639/.639 219 231 113 -1 over lap stock stall #6 .639/.639 223 235 113 3 over lap 3000 stall *pulls to 6700 rpm #7 .639/.639 226 246 112 12 over lap 3600 stall #8 .639/.639 223 257 112 16 over lap 4000 stall pulls to 7200 *possible ptv clearance issue TSP #9 vvt1 .635/.635 227 231 116 -3 over lap #10 vvt2 .645/.635 231 235 116 1 over lap #11 vvt3 .645/.635 235 239 116 5 over lap Parrish #12 .635/.635 230 238 116 2 over lap

Good luck. Cam selection is hard.
You could get 850wheel with a stock cam and a 15psi. It would be fun to try a pile of cams on a dyno. I wish they were easier to swap.

Hey Choda don't forget Jarrett Faggart of triple 12 fame....JFR. He's doing mine soon as I finalize my setup for him. For these I like #5 or 6.

Any of those cams will work... Like Richard Holdener says "any cam, is a "turbo cam". People have made over 1400hp on a stock LT4 cam...

To the question at hand there’s really not enough information to make a more informed decision than what others have said.
What is the turbo & configuration? System design intricacies? Base lift & durations only tell a small part of the story. What is the actual valve timing, etc? Quote:
I’ve reviewed quite a bit of Holdeners testing over the years, btw, & I remember the time when he first made that statement. I disagreed with it on a technical base then & I still do. |

If I'm buying a cam, I want it to best fit my car. I agree an aftermarket cam will make more power but there are difference in pd blower cams and turbo cams. There was a great article about a ls turbo getting a ls9 cam and then a ljms stage 2 cam. The ls9 made great power everywhere but the "turbo cam" multiplied it. Ill have to look for it. Those who voted #3, why did you choose it?

I sure didn’t. Those numbers don’t mean much to me. You want to talk turbo selection and I am your guy.

Speaking of turbo selection. I love match bot.
1 na 2 stock 5.3 at 15psi 3 cam and rev to 7k 4 rev to 7500 5 add boost 6 add more boost Damn a pair of 67’s has a giant island on a 5.3 and they spool quick. It will be interesting to see how close the calculator is to actual. https://www.borgwarner.com/matchbot/...6_wrsin=92044&
