ls1 header flanges

351 swap headers [ cut off flanges ]

round header tubes out and weld ls1 flanges on


alum intake 4"

i'll post some new pictures on the headers when there in the car and how they fit, these are mac 351 mustang heads by the way

drivers side, 3rd tube back is hitting the brake line and close to the frame, 4th back might need to be moved to fit the steering rod



pass side, fit great


more pictures later
Man...I never realized how many holes were in the engine bays!!! Are those all factory holes? The strut towers look like swiss cheese!
Good luck with the project!
