340 tunnel ram

I ran an STR-12 (Edel Street Tunnel Ram) with a single Demon 650 and it worked fine. Even with the massive plenum, throttle was snappy and it pulled until the 6500 limiter kicked in. MP 284/.484 cam. it came on at 3500, but even the low end was enough from a 340 in a 3000 lb 3.91 reared '65 A.
