Header Fitment Doesn't Look Right

Photo (1) is the right (passenger side) header. Photo (2) is the left (driver side) header. Notice the distance from the upper control arm cross-shaft bolts. The left side has plenty of clearance. The right side is extremely close. The right, rear bolt had to be shortened about 1/4" just to get the header installed.

These are Hedman HTC 68198. Hedman tech line tells me they have never heard of any clearance problems in this area. I think this is too close. Maybe a defect in how the tubes for this particular header were bent, or the wrong header slipped in along the way? Any other opinions?

When I compare this to my 1971, with Hooker Competition headers, the number 4 and 6 pipes are tucked closer to the block, allowing about the same clearance as on the left side.

Re: Header Fitment Doesn't Look Right

Is the motor centered between the frame rails? May have to loosen frame stands and slide everything as far as possible to side with lots of clearance.

Re: Header Fitment Doesn't Look Right

Mine is very similar - had to shorten that bolt too to clear.

X2. It certainly looks offset to the passenger side.

Re: Header Fitment Doesn't Look Right

As long as the motor is centered I wouldn't worry about it. Take measurements from the frame rails to the center of both the trans and crank. The dimensions won't be exactly the same. You're looking to compare an offset measurement if not completely centered.

People donít like to have to think in high resolution. Jordan Peterson. Thatís why we are forced in to so many binary choices.

Re: Header Fitment Doesn't Look Right

I have the same headers on my '67 with stock height heads and mine are centered. Something looks shifted to the right in yours.

Re: Header Fitment Doesn't Look Right

What year Chevelle are we talking about?

Interesting that some have suggested that the engine is not centered. Would be great to see some comparison measurements and/or pics. Would measure my '70 but it's apart right now.

Re: Header Fitment Doesn't Look Right

It's a '69.

I'll take measurements when I get home, tonight; however, I don't remember anywhere to make adjustments on the frame towers or engine mounts. The frame towers bolted straight to the frame, with no slots for movement. The engine mounts the same way - no way to adjust.

Friend worked in a frame shop. Chevelle # 1 rear ended another car striking the rear with its driver front. This caused massive damage naturally but not damage that couldn't be repaired supposedly back to factory tolerance specs. It was discovered after straightening that the frontal collision had moved the engine towards and down lower on the passenger side about a 1/4 of an inch via an almost unnoticeable buckled cross member engine frame mount area on one side and raised frame mount on the other of the cross member at the driver side.
Doubt this is your issue but just wanted to offer it up.

Re: Header Fitment Doesn't Look Right

I don't see the steering column in the picture, do you have it installed?

Re: Header Fitment Doesn't Look Right

No steering column. The body is not yet installed. I'd like to get this issue ironed out, before I install the body.

It's hard to get precise points to measure, but the best I can see is the engine is centered in the frame, within 1/4" or less.

Re: Header Fitment Doesn't Look Right

Check out the other thread about custom exhaust.

It may be cheaper for you to return those headers and find someone who can build a set of headers for you.

You will just have to check into that.

67 chevelle malibu / SS/ custom

Currently undergoing a metal work to remove all rust, if I ever get there.

Cant decide on prostreet or cruiser with a 4 speed.

Re: Header Fitment Doesn't Look Right

I think the lack of a steering column & shaft is exaggerating the view of the engine offset. Once the steering shaft & column are in place, I think it will look normal. I had 2" Hedman headers on my 71 and passenger side was close to the A arm bolt also.
