Anybody running a 360 tunnel ram on the street?
I've had an Eddy Street Tunnel Ram on the street since 2005
The smaller plenum helps a ton with a street car - the larger the plenum, the less velocity you have at lower rpm's
My Combo :
360 - std bore
kb 107's for a 9.4:1 comp ratio
stock 1978 small valve heads ( with air injection ports taped and plugged)
mopar p4452992 cam ( 474 lift 280 adv duration ( 230 ish)
stamped rockers
904
dynamic 9.5" converter
3.23 gears
The car has over 8000 miles on the street / strip with the setup - I've driven it in the rain( with a cover over the scoop )
never had any issues !
I started out buying the holley 450's - once i got them out of the box I returned them!
They had a mechanical secondary but no accelerator pump for them, it seemed like it was goung to be bog city - and in talking over the years with others who went that route, it in fact was a PIA with the design.
I rent with a set of holley 390's ( vac secondary setup)
I needed a holley balance tube to connect the secondary canisters together, to make them open at the same time :
My best pass was a 1.74 60' - 12.56 best ET, and 108 best mph.
with a ported 4 bbl intake and a holley 780 the best it would do was 1.84 60' - 13.20 @102
the T-ram made power everywhere for my setup.
I can get 16 mpg with the setup as long as I took it easy...lol
Last year I went with a pair of EZ EFI dual throttle bodies :
Talk about sweet! I gained 21 hp on the dyno, and have all the benifits of a modern efi system
Here is a before and after vid of the car running with the carbs and efi :
