 Subject: 68mm fastman or 69mm for my baby?
IP: Logged
Message:
Okay even though I'm broke as a joke, I think I'm gonna break down and buy a fastman tb for my dak. Here's the deal: I want low end torque, the only mod I have right now is the ho cams. I'm only doing mods that are dyno proven. The cams were awesome, more torque and better driveability. Dan Arcand recommends sticking with the ported 68mm as he says anything more sacrifices torque. I'm considering the 69mm simply b/c I have a 2002 and I cant imagine a ported 68mm would make a whole big difference. I'm fully aware Dan works them over quite a bit and they are much better flowing than a stock 68mm but I feel I may benefit more from the 69mm considering I have the ho cams in already, what do you all think?
2002 4.7 QC, auto, 3.92's, R/T rims, snugtop, and oh yeah...H.O. Cams!

the stock throttle body on your 4.7 is a 68mm. if you can afford it go with a 70. ive seen a few out there but i cant remember where. if you can get the 4.7 H.O. intake to go along with it. it works, i promise.

slowdak...I know mine is a 68mm already, but it has a 3mm restriction which makes more like a 65mm, just as the 2000's had a 3mm restriction which makes them more like a 62mm, fastman are "true" 68's, whereas the 3mm restriction is removed. That is the jist of my question, the 2000 guys are making more like and 6mm jump whereas I would be making only a 3mm, therefore I was thinking about going a little higher but I do not want to lose torque, my quadcab is very heavy espceially with the snugtop shell and r/t wheels, audio equipment, etc. That's also the reason I stayed away from the h.o. intake and only installed the cams, the intake takes away the torque the cams make! Would going over a true 68mm do the same?
