I would say you need to built a manifold set up for it. I was going to mock this up last winter(never got to it). Make a set of headers, upside and mount small turbos on each side, plumbed to carb box (from Paxton). Plenty of ideas.....................

I just recieved my turbo for my 390. I used AUTOCAD to design all of the plumbing and headers. This along with the 150 shot of nitrous (already on the engine) should throw this long bed 65 truck down the 1/4 somewhere in the 12's. I will start taking pics as It starts coming together.

Do you have a low compression 390 now? I think Turbos like to work in the 7.5:1 compression range.
An old truck 360 would be a good candidate :-) Even better, a 361. Talk about going from a dog to beast!

yep, ya need the lower compression ratio. I actually considered doing the turbo thing on my engine. There's a couple of guys at work that specialize in the turbo department. They don't have to be mounted up close to the engine to work well these days. One guy has one after his exhaust comes together up under the car...it's crazy but there really is just about no lag...I don't understand how it works so well. At any rate, the entry cost ran me off. If you want to see an unbelievable application of a turbo, check out the hayabusa videos off yahoo...comes off the wheelie at 140...top speed 258 mph!!
