Well after messing up last year and getting rid of my ls turbo gn I decided to sell my nova and search for another Buick . Found a 86 roller with 9” axle and nice moly cage . So it begins again .
goal is a 9 second driver that shifts itself. I have a good 400th and converter.
picked up a L33 to use . Going to gap rings and use a truck style cam for more torque out of boost and faster spooling. I’m thinking of sticking to a t4 turbo as well but not sure just yet .
Ended up doing a swap for the nova with twins and a dart block 6 bolt engine . Financially it was a good decision but looking back the Buick was what I wanted . So the nova was sold and I’m building back my Buick again .
Going low buck on this first combination just to get things rolling this year .
good trans and billet converter
stock L33 with a Texas speed smallish cam and a 78/75 turbo to start with. Going to see how far I can push this stuff and just have fun with it. Should go 9s fairly easy with no trans break . I hope
Going to start with this smallish torque cam to help spool without a trans break . And I’m starting with this little cheezy on3 7875 turbo I got from a buddy. Although he went 9.teens with it at 147 mph on a 5.3. Maxed out in a second gen Camaro.
not sure about the China turbo log manifold but I’m going to clean it up with a burr and try it out .
Glad you posted the pics with the 78/75 and china log manifold, was curious how it would fit. Did it weld OK-My Hornet had a small cam like that, and the 78/75, boost was pretty instant.
My idea with this cam and turbo picks are to spool as fast as possible without a trans break .
it took me a while to clean up the ports on the manifold with all the casting flash and it did weld pretty good . Very thick casting so it should hold the turbo up fine .
its not ideal but I do think it will work as good as the turbo on my 5.3. But not as good as a devided t6 for ultimate power.

Love that car. Great project.
I like the 4L80e for a driver that shifts itself. You get the overdrive as a bonus and the same internals as the 400th. For me, track car =400th. Driver/track =4L80e.
That is a nice option. I have just always ran the 400th and when the car is worked out I find I need a 3.42 to a 3.23 gear to control the launch anyway and they don’t street drive to bad with that gearing.
