I've been getting mixed reviews about how a 408 might not like breathing through the truck manifold to much...

so would it be worth it to convert to a TBSS manifold? If so, what all do I need parts wise beside the obvious manifold? (2002 return style f/s)

will one of these ots ported 90mm cable throttle bodies hook up to the iac and tps ect.?

also, will one in tank fuel pump suffice for a 408 with planned 480-500 on motor w/ a 200 shot.. or should I go ahead and think about doing the dual intank pump conversion?

thanks

 

you spent the money on a 408 - let it breathe properly. Get the ported fast 90

 

dont want to go changing the front drive system..

cant find a bracket to relocate my idler pulley.

 

there are several brackets available to EASILY do the relocation, get a fast, or even better a well ported Victor Jr. and let that 408 EATTTTTT..... The FAST 92 would be a bad *** setup on that truck. As for your fuel, the single intank should suffice on motor, get a dedicated to fuel your nitrous.... If you went with a Victor Jr. I have the perfect kit for you for sale... its an NX Pro Power plate kit... 100-500 shot...

 

all you need is washers and a longer bolt to relocate the idle pulley.

 

damn yall make it sound like the truck intake is molested puppy dog.

I guess I have been swayed.. ls6 it is....

 

truck is the best stock intake out there for a heavy truck IMO. i switched to ls6 and now im switching back to the truck manifold.
