Top swapping is only for going supercharged. No reason to swap to the L67 top end otherwise. That's like putting on a condom to jerk off.

I will have to re-read and try to understand the different engine codes better. The way I was reading I got the impression I could swap on the slightly better flowing heads (L26 Series III) onto my Series II. Back to reading - may have to make my own table just so can learn this stuff better....

Re: Top Swap Info and Faqs, Also lots of 3800 Info
You could. But two things. First, the L26 heads don't really flow any better. Second, it'd be a lot better to just get ported heads.

For the time and effort, just get ported heads, the flow difference is minor, and will not make a difference on the Butt dyno, you could do a head swap is what your talking about, when we say top swap we mean the supercharged setup on the na bottom end, or visa versa(for turbo applications) swapping stock NA heads for stock NA heads is a waste of time, gaskets, and effort

Re: Top Swap Info and Faqs, Also lots of 3800 Info
DONT DO A 97!!!! JUST DO A MOTOR/TRANNY SWAP!!
the vacuum controlled transmission that comes in 97 SE/GT's is straight junk and youll have a hella hard time controlling it with the l67 top end.

maybe i will just sell this 97 and just buy a slightly newer GTP then, if i have to buy a whole motor and tranny for this car its not really worth it.

Re: Top Swap Info and Faqs, Also lots of 3800 Info
not if you find the right deal and a motor/trans. i bet if you look you can find it for less than $1000 from the right place.
-
Re: Top Swap Info and Faqs, Also lots of 3800 Info
Thanks for the idea, i will have to do some digging then and see what i can find
-
Re: Top Swap Info and Faqs, Also lots of 3800 Info
well i made some calls to the local salvage outfiits today, and i would be looking at over 2k for a motor and tranny, so i think i am back to selling this SE and just buying a GTP...
-
Re: Top Swap Info and Faqs, Also lots of 3800 Info
yeah, you can pick up a non-molested one for like $3k nowadays anyway.
-
Re: Top Swap Info and Faqs, Also lots of 3800 Info
So from what I can Gather. I'd do better to find a Newer GTP motor and tanny for my 97 GT instead of doing a top swap.:th_wtf:

Re: Top Swap Info and Faqs, Also lots of 3800 Info
that vacuum controlled transmission is what is your problem. if you didnt have that then you would be money.

If you have a 97 GT you have the 4T60E which is the vacuum controlled transmission.

So as I said before I'd do better to find a newer GTP model Engine and Trans instead of buying the parts to do a top swap on my GT.....Right???
