My junk went 457/424 on an F11(full bolt on's, M6, 12 bolt/4.56's, 28" slicks)with three year old TEA S1.5 5.3L heads. The F11 can make decent power for a baby cam if the parts are matched well. Slap on the AFR's and I'd bet you'd see upwards of 465-470ish....

WOW! I was thinking about changing to a bigger cam but after hearing that I may not. I've got a friend doing a set of ls6 heads for me w/ 2.02/1.60 valves and I'm hoping for similar numbers and flow characteristics to the AFRs...may see how the car does with the F11 in it (in the car currently). SlowETz did you use the ls6 intake when you saw those numbers? Are those numbers SAE? When/where did you have the car dynoed? Have you run the car in the 1/4 since you ran those numbers? Sorry for 20 questions, those numbers are just VERY impressive

hell yeah man, those numbers are impressive.. you probably would be making more but that 12 bolt is probably eating up power too.. im really looking into f10 or f11 with afr heads..

Those #'s are w/a FAST 90/TPIS 90. Car is a heavy pig, so the numbers aren't that impressive. Best ET/MPH is 11.47@123.6 NA at 3750#'s on a 6k mile motor.

Yes those are SAE corrected numbers. Car was dyno'd last spring and again mid- summer in Atlanta. Allan(FMS)did the original tune, and Mike @ GMMG tweaked it after the 90/90 swap.

The same F11 w/an LS6 intake and stock ported TB with all other mods the same did 434/416 and went 11.70@120mph NA.

Thanx for the props guys.... but I/m feelin' SLOW on this board.

Looks like I may be goin' w/a 408" on the hose this year.... the 346 may be up for sale in the coming weeks-

That is damn good power for a smaller cam!
