racing beat.....
 

ok, which is the best header from the site?? they all seem so similar.
and if I was to use another carb.....webber, or holley??
I hear that webber gives much higher power output, but I'm not sure.
and if I go to a holley, which holley? or, Which webber?

get the Road Race header front section. it's the most versatil choice in my opinion, if you're only buying a header from them. you can use a collector for price and simplicity or you can buy or fashion a dual system based on the front section.

as for the intake question, there's a pretty good thread in the Gen I Archive that compares many carbies. it will come down to personal choice. all i will say is that the Holley gives you a similar feeling to the Nikki, the Weber side-draught is good on the low and mid-range. i didn't care for it much on the top end, but perhaps with some jetting and venturi work ...

i have no experience with IDAs.

ok, I'll look into that.
