looking for 340 tripower and ...........

6 pack intakes are hard to find as of late, so I was told. Check Mancini racing.
I waited and waited for good prices in 6 pack parts. Caught a few going out of biz or just simple get it the hell outta here sales. You have to be able to wait and wait for a good deal. Year one (IIRC) wanted something like 6 or 7 hundred for the center carb. I waited a long time and nailed all 3 carbs for approx 600.

Good luck on your hunt. Have the ability to pay right away! Just I case you get a screaming deal. Leave no stone unturned. Goggle away!
