what size headers for 632 motor?

632 bbf what size pipes and collectors profiler heads are what ill be running just gotta buy them...soon   

nitrous?

yeah a kit or two

BIG  

what he said, nos deal aint as pickey other than it wants to get the stuff out.

big it is then lol. i was thinking of starting with 2-3/8 to 2-1/2 to a 4.5" collector? am i in the right direction? side exit headers.

I run a 2 3/8 into 5 w my pos, Id think that would work.

632 on bottle.. Don't worry about the step, 2.5" primary, 5" collectors, and keep em short!!!!!!!!!!!!!!!

The only reason to do a stepped deal is that you already have the material.  Other than that 2.5 to 5 collector.  Or freakin zoomies like a lot of guys are going to.

bullhorn zoomies ftw.....

ok thanks for the help guys. and also why keep them short? just curious.

X 2   

so the piston can push all that chaos out of the cyl as fast as it can.

The header on a big inch nitrous deal is not as big of a tunning element as say a combo thats not running the sauce.

My headers I have for sale would be perfect for that engine. Just change the flanges.
I'm selling them for less than the material cost.

wouldnt mind picking them up if i could use them but think im going with a side exit with this motor...who knows might just go with the A441 heads if i can find a set

Side exuast is in vogue right now, but they sound like shit.
