340 exhaust manifold vs stock 318

better than that AJ
we had two cars
one was an AMX which is a Javelin with 12 inches taken out of the rear seat 12 inch shorter wheelbase

then we stretched the front end 12 inches- sort of a Dodge funny trick
spliced two hoods and fenders together
painted both with the Red white and blue big stripes- as with clothing big stripes make you shorter
back in the day we had big red numbers on white magnetic media
so we ran one through tech twice with different numbers
(another Smokey trick)
essentially setting the motor back a foot and with the front suspension in front of the motor we could lower the driveline with a small flywheel and dry sump
cornered like on rails and you could get on the gas earlier coming out of turns- braked better too
just had to be careful not to be too fast and not let anyone see both cars together
rims and tires were limited and that limited the rotors
they measured the wheelbase a couple of times and found- yep Javelin but stock steel - well maybe just a little lighter thanks to a rust removal company in Santa fe Springs-from the cowl back roll cage did all the work
