12 second 340

a 340 should be easy to get into the 12's




my 360 went 12.8 at 106 and that was having to baby it off the line because of crappy street bias ply tires... and i haven't really started to tune the thing yet... that was the first and only time so far that it has been to the track....

here is the basic combo..


mp pre magnum short block 9.1 to 1 version

the small chamber eddy heads right out of the box

508 mp cam that came with the short block

eddy performer rpm intake with a out of box 780 vac secondary holley

msd ignition

headders

about a 3000 converter

904

3:91 gear..




i know quite a few guys going mid 11's to low 12's with a similar combo.. they are running a little more cam, 4:30 gears and higher converters...


its really a cheap combo if you price it out..


i'm sure a 340 would react really good to these types of mods.. if its a 10.5 to 1 340 you would probably need the open chamber heads....
