20-90 run
figured i would post up a quick 20-90mph run from today and let ya'll check it out. not nearly as quick as some of the ones i've seen on here. i'm runnin 3.42s so a stall and gears would probably help it some. you may have to turn up the volume a little.

thanks guys. i'll prolly do the transgo kit when i do the verter.
yeah it shifts right at 5700. i was thinking a good rpm with this cam would be around 5900, but when i put it on the dyno 5800 or so it nosed over. its not valve float, so i'm a thinkin time for some heads.
BTW, at what rpms are you shifting.... looked kind of low (~5700rpm) for a cammed 5.3.

What are the specs on that cam? My 222/224 that was in my 5.3 pulled hard till 6600 and probably could have gone higher but it had a 165,000 miles now its dead and a 408 is going in its place.

the short intake duration plus the 5* advance slams the intake valve shut pretty early in the game maxxing cylinder pressure, prolly somewhere around 2800rpm (just guessing), which makes it kind a torquey i think. gamedawx53 has got the same cam, he could prolly fill you in as well. i have been battling an intermittent KR during PT driving that is wearing on my last nerve. its not huge amount, only 1-2* very sporadic and only during lower rpm with a mid-load on her...blah, blah, blah, so i have been seriously considering a change so that i can lower the cylinder pressures a bit down low.
hows your exhaust ran from the muffler

it exits pass side (dual 2-1/2") in front of rear wheel. makes it a little unpleasant for the rider sometimes when the window is down

I agree
**** load of off idle tq
Mine feels like it starts to drop off about 6100
Okie
how much timing are you running in the wot cells?
ive run up to 39* and havent seen a bit of KR
but I have seen some at part throttle though
