Guys and gals I got some questions that I was wondering about when it comes to building an engine. I would like to build a 3.7 with the goal of about 300 crank horsepower. I would like to know if anyone has ever taken the 3.7 apart to analyze the bottom end and determined how much horsepower the stock bottom end can reliably handle? My next question is on stand alone PCM's is there anyone that has experimented with one and if so how much does a system cost? My goal is that I would like my truck to have better power in the 2 and 3 gears. Also what is the feasibility of attaching the 545 transmission to the 3.7? Because I know that a great transmission can make a weak motor get the job done such as the new Ford Ranger 5 speed auto. Also on a side note how long do the new composite intakes usually last? Thanks all the input.
