Thanks to madd maxx looks like the Mutha Thumper might be to big for my lil 5.3 so might just go with the Thumper....
damn brian, your cam is gunna lope hard.
im keeping it NA so i want it nasty an all in ur ear when i go by :lol:
looks like your set with your mods,im happy with my little thumper lol,i just need a 3200 pi stall.
yea I already have a 3k Yank so i think with that Thumper cam and my reworked heads and bigger injectors i should be good to go...
yes sir,order it bro,i want to hear that muthathumper:)
I almost went with one of these cams.....it was a coin toss...LOL
Which cam did you get Dale???
I'm also running a 5.3L and I just put an Isky 224/233 at 112 LSA in it. A 3K stall isn't going to be enough for it. I'm going to have to run a 3500 to get the rpm's where I need them... this may be the case for your thumper, too.
I haven't had it tuned or dyno'd yet, I'll be posting numbers when I do.
