12 second 340

im rebuilding a 340 right now that did 11.30 in a 3400lb car.

KB 10:1 pistons
mopar 292 purple shaft cam
ported j heads......im going with ported eddies for a little more oomph and a little less weight
4.56 gears
4500 converter
air gap intake
cast crank, internally balanced with refurb stock rods and arp bolts
running an internal balance stock balancer

as for a timing chain its running an undersized one because my block was line bored

this combo twisted two pairs of stock axels in the car it came out of, and should put me in the high ten's on a good day when properly tuned
