I'm kicking around an idea for Trouble and need some leads. Where would I look for an intake for a tripower setup for a 390. I know of sources for the Holley carbs, but what about the intake? I don't know if I'll actually do this, but I'd like to at least research it.

The 62 and 63 thunderbirds came with an "M" code that had a 390 tri-power setup.

If you run Edelbrock heads the ports wont line up. Early 390 used a tall port and the Edelbrocks use a med riser port.

It'll run, but it wont make any power, it'll be show only. The other option would be to have the intake welded and ported to match the heads, but sorta big bucks just for the look.

If it were me, I'd buy a med riser dual quad and put two 450 Holleys on it if you have to have multiple carbs. It'll look better, perform better and you can buy it all aftermarket. I have done 3 of these on 428's and one on a 454 stroker from a 427 block, its a nice setup.

Although its still hard to beat a single carb for performance

Let me add that 2 450 Holleys cost 360.00, cheap as a single 4 barrel and are calibrated for a street tunnel ram (works great, even did one on a stock 428 CJ, bolt on and go), add repop linkage, and the repop manifold, you got a bolt on system. However, I am not sure of your hood clearance, the leading edge of the air cleaner gets pretty close to the hood

I'd estimate
2 carbs - 360.00
Intake - 550.00
Linkage - 100.00
Air cleaner - 100.00
Other doo dads - 100.00

1210.00 total. Awesome looks, great performance, BUT, not really any better than a 4 barrel. Thats why although I love them to pieces, I just went with a single 4 on my 427 and 489. For that money, I will go EFI when it comes time, but if you want the look and easy driving, the dual 450s are awesome
