anyone put a tpi on a stock lo3 and notice any real power increase ??
ive searched and find mixed results.i have a 91 caprice with a stock lo3,im almost done with making it into an impala ss clone (on the outside) . i dont want to take chances with a used lo5 motor because the motor in the car is great, just a little weak for the size of the car,i like tpi and i could drop a standalone tpi on it in a day,but would it be worth it?a tpi on a lo3 should be a torque monster but thats theory...............
a little extra torque for around the city would be nice.not looking to run 11 seconds.and a tpi in a impala/caprice would look badass.

 

i had a lo3 with my tpi on it before i spun the bearings. it had noticable increase on the butt dyno. now i have a lo5 with my tpi and wow. yes torque monster is the words i would use.
