Tunnel Ram on Street?
Sure is worth trying a tunnelram,just get a good combo of parts and tune it right.
Dont know how tall the MP tunnelrams are but i ran a Eddy tunnelram on the street and it fit under the sixpackscoop on my 73 duster with a couple 2x?" aircleaners that just rubbed alitle on the underside of the scoop,ran with a couple of 750 proforms that in my opinion where to large for the combo but those saying that tunnelrams only work at high rpm and are useless on the street are clueless,its all in the combination of parts and having the knowledge to make them work together,if i did i again on a good stockstroke street 340 i would probably go for a pair of 500cfm edelbrock carbs,600-650cfm 4150 Holleys or the legendary 660 centersquirters.
Stay away from those crappy holley mechanical secondary carbs with no secondary accpump.
For what its worth a friend ran a pair of 500CFM edelbrocks on his tunnelramed XR280R cammed Eddy RPM headed 383 chevy and those where good enough right out of the box to push his very nice 65 Malibu into the 11:50s with just 3.73:1 gears and a 3000rpm converter shifting at 6000rpm The thing was easy to start cold and warm very nice to drive and the thing was an absolute animal when asked to.
Here comes a pic of my old tunnelramed 11:1 compression solidrollercamed daily driven 340 while i was puting it togheter. I used to have a pic of the carbs under the scoop aswell but i cant seem to find it.
Oh and yes i ran it with PB and PS,the ps pump did not seem to appreciate the rpm over tim but that could probably be sorted with different pulleys and the PB was not always happy in very slow stop and go trafic but it doesnt realy mather and it was never realy a problem, either a vacumcan,vacumpump or a smaller cam would have taken care of it but it was ok since there usualy isnt much need for all that assist anyway at low speeds and at higherspeeds there are plenty of vacum for the brakes anyway,this did not change due to the TR it was the same with other intakemanifolds aswell.
