Topic: 4.3l exaust... post your pictures.

When doing 4.3l swaps, what does your exhaust routing look like?
How much frame clearance do you guys have between the exhaust manifolds?

Theres anough clearance. However I pushed my engine as far back as I could to the fire wall just to make sure I had as much room as posible for the radiator and the fan. It looks like I have lost all of my pictures on my computer though, I'll have to take some new ones when I get a chance.

Mine was very tight to the frame but it did not hit. This is with stock S-10 Blazer manifolds.

What manifolds? stock (yr)?  are they all the same from early 4.3 to late?

Can you take a pic of the exhaust manifold on the pasenger side wheel well where the brake lines are? So I can see the gap between the frame?

I have the thorley headers.  Before I did the drivetrain lift the collectors were sitting on the frame rail.  After the lift there was plenty of clearance.  I ran my cross over under the converter to a Y pipe and down the driver's side to the rear. I cut a hole in the cross member and ran the tubing through it.  I had looked into putting manifolds on but after some measuring it wouldn't have gained any clearance. I'd recommend getting the motor up high in the engine compartment to gain a little clearance.  You will open some other cans of worms doing this though.  You can see my stuggle in the buildup thread The yotalet buildup.  Good luck.

looks like the hood is going to get a huge k/n sticking thru it. thanks for the Idea for the tranny tunnel.

I cut my hood and made it into a cal induction type to fit everything without a body lift. I didn't have a filter on top to worry about but it helped with the radiator and helped get some heat out of the engine compartment.
Sorry I don't have anymore pics. The only one of the passenger side is the last one in the other set I posted.
