TR-5 Tunnel Ram

Yeah i believe it has teh tall plenum the bottom is cut out so its an air gap now instead of solid like yours the 450cfms are vaccum secondary's list number 4548 called edelbrock today and they said its rated from 3500-7000+ looking for a 340 block now and am going to run 11:1 compression also and probably a 3500 stall with either 4:10s or 4:30s havent decided on a cam yet i think i got a pretty good deal for the intake and carbs for 500? carbs just got rebuilt ill take a picture of it when i get it in the next couple of days when i get some free time. But glad to hear it isnt a bad intake lol!
