Hi all. I'm doing some 3800 upgrades for a friend. We will be install an XP can shaft with all the valve springs and retainers and timing chain upgraded as well. Adding a short stack intercooler and a smaller pulley. Ant remember the pulley size off the top of my head. Can we continue to use the stock exhaust manifolds? There's not much budget available for anything too fancy. Whaddaya think?

Thanks

Yes, but I would recommend a plog.

No doubt that the P-Log flows far better that the stock front manifold. We had a couple here and decided not to use them but I kept one just for modification and possible future use. When installed, the PLOGS sit very close to the A/C compressor. I am uncomfortable with that fit- too much header heat near the compressor for my taste. Anyone else have these concerns with the ZZ P-Log?

Mine WILL NOT FIT WITH THE AC COMPRESSOR

We did not experience this when we tried fitting the PLOG but did find that it sat about 1/16" away from the top of the compressor. That was when the engine was on a stand off the car. I believe that the PLOG was designed for the Grand prix 3800 so if you have an engine for another application fitment issues may happen. The assumption is that different year 3800s and different applications affect the fitment. Our experience was disappointing as you have a good flowing product with installation issues.

Us folks who live at the lower latitudes like it, plus if I didn't have A/C my wife would not ride with me. You only lose horsepower when its turned on.

What do you so for the rear manifold? I'd like to put my shift cables back in stock position and have some actual exhaust.

If you don't mind a little extra work I have liked using the Mustang manifolds in the past for modified engines as well as for 4 speed manual swaps to get rid of the upper crossover cleaning things up quite a bit and keeping heat away from the throttle body

the PLog is a very simple design, it wouldn't be hard at all to replicate if you have the time. which would allow you to also correct any a/c clearance issues.
