Hey everybody, I'm a long time forum lurker, and a first time poster. I've tried my best to figure this out without resorting to adding another header thread to the forum, but I don't think I have a choice, I'll try to make it as quick as I can.
1969, 350 with 441 oval port heads, M-21 4 speed, power steering (I think the standard steering box), power brakes, no A/C, alternator is on passenger side, running a stock suspension other than the 2" drop spindles the previous owner put on the car.
For quite a while, I've had heat soak problem where my car gets hot and won't start for a while until it cools off. To solve that problem, I decided to upgrade the uncoated Hedman hedders to some nicer ceramic coated headers, and also upgrade the high-torque starter to a mini high-torque starter. I did loads of research on this site and decided on a set of Doug Thorley THY-376Y1-C headers which I ordered from Summit. I also ordered a powermaster starter which I had problems with but that's for another thread.
They came in, and I had a garage attempt to install them (while doing some other work), and the drivers side header interferes with the clutch linkage. During my research, I know I read SEVERAL posts from members who have a 69 small block 4 speed who use this header so why won't mine fit? The rest of the fit was awesome and tucked up very well and hung no lower than the subframe. Looks like I'll be returning them.
Summit's website said the 376 would work with a MT. Thorley's website said it would not, wish I would've looked at that before I ordered them.
I just called Summit and they recommended the Doug's D375Y header, and also stated that the Thorley 376 did not even list the Camaro on the application list!
Why would the Thorley 376 headers not fit my car? Should I order the Doug's D375Y header that Summit recommended? Any help would be greatly appreciated!
