1970 GTO the next project

[jasonL78]

I will post some pictures in a couple of days. I've been beating myself up the last couple days trying to work around these headers. Who would think one little change in the engine bay by adding aftermarket heads would create so many problems. From brake lines, alternator and power steering brackets to the clutch return spring. I have the brake lines all made and test fit. I ordered the power brake booster and that showed up damaged. We just can't win. I had to get creative with the clutch return spring. I made two brackets and both failed. Just no room for the clutch return spring or a bracket. I kept walking away from the problem and then the third attempt was the best and simplest design. I think it will work. I'm currently installing the sound deadener and rug in-between working on the engine bay. You would think final assembly would be bolt on and go, but that isn't always the case. These pictures are during mock up I will be painting the bracket and starter. Oh YA and I still need to come up with a way to get the wires to the starter, as the header tube is in the way where the original wire channel was run. That's going to be another fun challenge. I guess that's why its called hot rodding.

Did this car have the 400 starter wires running down the tube between the #5 and 7 cylinders? That won’t work with headers. You can use the 455HO/SD455 wire routing which runs across the intake, down the front of the block, behind the power steering pump and along the oil pan rail. It uses a different metal tube to protect the wires on the front of the block. You will need a starter heat shield by the way.

Is there so many problems just to add headers or the problems are increased by also using Aluminum heads?

Pure Stock is the way to Rock :-)

These are Edelbrock aluminum heads and must be wider than the originals putting the headers close to the frame rail. Only Dougs make these headers for these heads they have a D shaped exhaust port. I have a friend with a 69 Chevelle with a 454 and headers and he has all sorts of space around the frame rails.

Steve that is correct. I will look into that tube for the 455, do they reproduce it? Is the heat shield factory? Not that it matters but if I can install one it might save the starter.

Looks good,and well done.

I asked a friend of mine who know 69 GTO's and he said there is a ground strap that goes from the passenger side inner fender to the front of the frame somewhere.

may be different on a 70?
