We've all seen twin turbo builds before and this is going to be a little different. This is a 366 flatbed turd. I got this motor for free and the only thing I could think of to do to make any reputable hp was to bolt two Chinese turbos to it and run it at as much boost as it'll take. For those that don't know, the 366 is the 427 tall decks ugly cousin with the same crank but smaller bore. You can't bore it to a real big block bore, but it does have about a 4 inch bore and a 3.76" stroke. It's like a 383 in a heavy, big block, canted valve platform. This is a 91 tbi motor. I don't like tbi for tuning so I tracked down a really old 4 barrel factory manifold. The 4 barrel manifold actually has larger diameter runners that match the head ports perfectly, unlike the tbi intake that had tiny runners. I guess that'll raise the powerband about 500 to 1000 rpms which is fine since these supposedly peak around 4000 and provide more airflow. I'm keeping the short block stock including the cam. It has dome pistons and 427 tall deck truck heads. My best guess is if it works it'll make around 450 hp and 600 lb ft at 10 psi. I'm not doing this for numbers though. I see a lot of hate on these motors and I figured I'd put 500 bucks into it and see what it runs at the track. If I'm not happy, I'll add two Chinese intercoolers and swap the wastegate springs.
