Need help about Pontiac Trans am, Firebird and Formula?

Will first off the 1975-1978 Trans am engines are all smogged filled idk if you live in the U.S., but chances are they are smogged. Meaning the compression on the engine cylinders are turned done and has different items such as the PCV Polluton Control Value on it to help filter out the engine which causes a huge loss in more and performance. Your better off importing a 93-99 trans am with either the lt1 or ls1 the lt1 enigne has 275 hp and 325 ft torque and the ls1 is an aluminum block which is litter then the lt1's cast Iron block and pushs out 305 hp with 350 ft. torque. The trans am in the mid to late 1970's are like anyother clic car of that era. The Muscle car look, but lacks the the muscle car power. Plus you get horrible gas mileage for the performance in the clic trans am/ where as with the mid to late 90's trans am your getting a little better fuel mileage with more performance.
