well we put that intake on because of the cam and pistons we are going to be putting into it soon(12.5:1, and the lift of the cam was over .650 and it had massive duration, i can't remember what exactly i will go look in a sec.) We ran it today with massive tire slip(crappy stock car tires lol) and it still ran a 7.9 at 91 mph pretty good for at over 4000 ft. Next year we are going to run a 250 dual stage shot, and get some proper tires under her. Also needed is a higher stall converter up closer too 4500-5000 it stalls right now at about 3200-3300 which is way to low but we still spin tires launching from that

I will go check with my father who did most of the engine swap, i am pretty sure they are truck headers, i know the passenger side fit right in but to drivers side needed a bit of work done to it, for motor mounts we used old ford econoline van motor mounts and welded em in place.

I think with a more modern Victor Jr intake single plane manifold you will pick up some power. Unless you are spinning crazy RPM (beyond 7500rpm) that tunnel ram is outdated.
A C6 sucks up about 30-40hp vs. running a C4 due to parasitic drag from heavier internals plus they are portly trannies...
Other than look looks like a fun car.

well we had a c6 that was just rebuilt so we figured we would use it instead of going out and buying a c4, same goes with the tunnel ram. Although this one has much shorter and smaller runners then any other tunnel ram i have seen
