PJC Racing

347 fron Coast Highperformace or FordStrokers, they both use Probe assemblies.

There is no replacement for... well, you know how the overused saying goes. Heard nothing but good things about CHP, nothing but bad about DSS

92GreyGT

Not to be a smart *** and not to **** anyone offbut how many of you have actually had dealings with DSS, as in bought an engine from them? Hearing DSS is bad isn't the same as havingbought an engine and had some problems that weren't taken care of by DSS. Every partof my engine except for the block, intake, and cam was bought through DSS. I never had oneproblem with any of it. CoastHighis also a great place todeal with.

redline is not a certain RPM that you cant exceed it just depends on where its best to shift. It all depends on how good your valvetrain is and mainly where your cam is set to make the most power. Best thing to do is get it on a dyno and see where your making power. Most guys shift between 5500 and 6K
