340 tunnel ram
i wont get into the argument over t-ram or not...
ok i might....
my BEST incrementals with a ported out stock 4 bbl and a holley 780 cfm vac sec was :
1.86 60'
13.20 @102
My BEST with the 2 holley 390's and eddy street-ram was
1.74 60'
12.56 et
108 mph - the 12.56 and the 108 were at different runs... i generally run 105-106 in the norm
i get 16 mpg with the 2-390 holleys
I RAN the 450's before - they have no secondary pump shot and are a mechanical seconday - i had a bog I could not get rid of
only thing i ever did with my 390's was to put a lighter spring in the vac secondaries and add these : they have a tube that makes both open at the same time.
holley part number - 20-73
the lokar cables made kickdon and throttle control easy !
other side
For anyone saying they are a waste of time and they dont run and this and that - they have not run them - thats for sure - the t-ram just keeps pulling! AND - i could never get a dual plane and single 4 to 60' even close... so it having no balls down low is a myth as well.....
I have had it on there over 5 years and have about 9000 street and strip miles on it - no problems - i cover the scoop with a shower cap when it rains and keep driving!
I run a mopar 474 lift cam p4459229 small valve heads ( 1978 stock castings ) and a dynmamic 3800 stall 9.5" converter - 3.23 gears out back and 26" tall tires.
