I posted earlier about phenolic spacers and have been doing some research since then. Do you think this would fit our Series II engines, or is something different ?

I'm looking at the doohickey on the upper right hand end of that thing, and saying no, it won't work. WTF is that for? Looks like EGR? It can't be for a distributor......large coolant passage?

I dunno. But no, that looks too different from an L36.

So then a NA 3800 Series II does not remain the same from one vehicle to another. Thanks. They shouldn't call it by the same name, then. Less informed people such as myself are apt to become confused.

There is one available for the series 2 and it kinda works from what I have read.

yes yes I know zzp made one..um it is helpfull for top end but as most of the product provided for the series 2 3.8l it is based on getting your RPMS much higher than a stock engine. This means average real world change on most of these parts are slight on a stock engine. Not a bad thing at all but unless you build the engine to turn that torque into hp you are not going to see big gains.

But the prime objective would be keeping the upper intake cooler and less likely to fail, no? (In doing so, you would have the added benefit of a cooler, denser fuel/air mixture and longer runners for added torque).

...yeah, I saw it as more of a safety/insurance mod (like a tranny cooler?)

That'* why they list an actual vehicle application too....That way if you use it on another type of 3800, they can't get sued!

tricky little guys...
