I received my headers yesterday from speed engineering and I have to admit they are absolutely nice I can't wait to install with my Ls 408 stroker

I have the 1-3/4" Speed Engineering on a 5.3 in my Cutlass. I had to dent a tube on each side for clearance, but overall the fit and finish is spot on! You do have to run header specific plug wires though.

Looks like your LS is mounted as far rearward as possible without cutting the firewall? Were your clearance issues the rear lower A arm mounts? Which tubes were "clearanced"?

On the driver side the #1 tube hit the lower control arm mount.

On the passenger side #4 tube hit the frame, but just barely!!

My LS looks to be mounted at least 1" forward of yours (trans dipstick stock location) looks like they wouldn't fit, what do you think?

You would be fine on the both sides clearing the front crossmember, and actually if my motor was forward the driver side would likely clear fine. The pass side might still hit the frame. Honestly, for the price I didn't mind taking a torch and hammer to them. If they were the pricey Hooker, Hedman, etc I would cry while dinging them.

What is the P/N of those headers?
