I got the oil pan on and my valves adjusted too.So it's almost there.I test fit the long tube hedmen headers.They fit good but they exit right into the little brace coming off the frame.On the passangers side I have about 3" from the collector before it hits the frame brace.Thats going to make for a real shrape turn there.I was hoping to do this myself because the local shops want $100-$150 just to hook up to the collectors,that using the old system.
What do you guys suggest I do.
1.Get some differrent pieces of exhaust pipe and make what I can.
2.save up until I can have a pro do it.
3.Buy some of that flex tubing until I take it to shop.
4.Go back to the short tubes.
Would going to the 66 motor mounts help any?
Hedmen told me I dont need them for this install.

One last thing the battery cable I just installed from the truck sites only about 1/2" from the collector I'm going to wrap it in heat tape,but is that enough.

Thanks for the help,I really only set out to change my timing cover gasket.

OK i realize you don't have a whole machine shop, but heres what i'd do if it were me. Buy a 2 1/2" exhaust "U" bend , cut the pieces (hacksaw works fine)to form an "S" shape for each side to fit the frame braces.

Mark them with a felt pen each side where they join so you can put the puzzle pieces together when they get welded.
Take those pieces with the 3 bolt rings to any machine shop, muffler shop or other welder and simply get them welded together. Your exhaust goes past this point and can be cut to join these pieces and it's only 2 more welds when you drive to a shop.

Even if your exhaust is 2 1/4" or smaller use the 2 1/2" out of the headers for that sharp bend, the existing pipes can be flared on the end to mate up.

That much to graft your old system to new headers? Holy Crap!! I only paid $200 for a complete aluminized dual exhaust with mufflers from the manifolds back including chrome slash tips.

My suggestion would be to find another muffler shop.....

Even the local (Charlotte NC)Midas/Meineke is much cheaper than that.
I would call around a little.
Try to give them an estimate of the length and quanty of bends and hangers/clamps for your installation.
Maybe they are just quoting "Highball" figures since they haven't seen your application.

You sure did extend that timing cover project. That's cool though, since you'll notice it whole lot more!!

Have you started it yet with the open headers? You've got to break that new cam in right?

Also, I'd call a few more muffler shops and tell them you want your pipes to mate with your new long tubes. It should be $50 or less to cut and weld the collectors to the pipes, assuming your head pipes are in good shape. It would be a lot of trouble, imo, to buy pipes, go back and forth to a welder, test fit, and take the pipes back if they need re-welding or adjusting.

Just me...

Congrats dude!!
