Your clearance will depend on wheel back-space. I run that Header, but with M/T drag fronts on 4" Welds. Most probably when you make a hard left turn so that the back of the wheel/tire is closest to the Header tube that 60 series tire will be verrrry close.

Sorry i haven't experience with a wider tire.

These wheels are not back space the rims go out.

So you are saying the surface that bolts to the hub is even with the edge of the rim?

jfb

yes the center section is even with the hub, I seriously hope that someone has had experience with these headers on the street and most of the time unless using nitrous i drive to the track. I do not want to find out on a long trip if i am going to have trouble so far with regular driving there seems to be no problems but you never know until it is to late with my luck.

hey 70wcars i have 1 more question for you on those headers. I lifted the brake lines for more air circulation but have you had any heat problems with your brake lines at all along the frame. jfb.

ALL wheels have backspacing. That is simply the measurement from the inner lip of the rim to the wheel mounting flange.

jfb

thanks for the correction joe i always thought of rims as reversed or totally back spaced.

70Wcars

Nope, but my car is a strip only car so not much time for heat to build up. I just unbolted the Proportioning valve from the frame then bent the lines enough to give me air space between the Header and the Brake stuff. Didn't even re-bolt the Valve to the Frame, just let the brake lines suspend it. No issues in 6 years like this.

thanks for the info i bent the lines carefully when i installed the headers and lifted them above the tube for air flow the i put header gauze over the lines close to the tube this new combo will be a real shot in the a-- so to speak.
