1984 trans am ws6 lg4 3.23 gears, 4 speed auto

hows it run right now? mid 16 at best.

Thanks.
What do you think it'd run with a true dual exhaust, headers, and an L69 intake?

the intake manifolds are the same between the lg4 and l69. the air cleaner assembly is a little different and will help you a little (like .05secs) dual exhaust is not the way to go on a bone stock motor, you will likely loose bottom end due to a lack of velocity control. especially an 8.5:1 c/r 305. a set of shortie headers and a single 3" exhaust will be MORE than enough. if you can get some 3.42's, and a "b-stall" torque converter along with the afformentioned exhaust mods, and a sticky tire and your garaunteed 14's.
