1994 Impala LT1

Asked by May 12, 2010 at 07:01 PM about the 1994 Chevrolet Impala

Question type: Car Customization

Have a friend with 1994 Impala with 350/5.7L and 3.73 rear end for more torque.
Besides all upgrades K&N Intake etc...... how can I boost more performance out of this baby?
Dyno and re-flash PCM is done, how about Hypertech Chip??

Any advise, much appreciated.

hey, have you tried looking into a bigger performance cam. those lt1's wake up a lot with cams. you can also do headers for the exhaust and a larger diameter throttle body. those are all flow adders. you can also get a hotter coil that will deliver more spark to the opti-spark system. also try a 160 degree thermostat. it keeps the engine cooler and fools the coolant temp sensor into thinking its cold and will richen the fuel. just some thoughts.
