I was starting my stroker build bout a year ago and heard about mike at mrl so I thought I will give him a call and get his opinion and see what he has to offer, so upon calling him I told him the parts I already had and he knew everything about them and how they worked cause he had used all the stuff, he was a truly first class guy who didn try to push sales just like to listen to what you had to say and then told you what he had learned and what worked for him, he is one of the few people in the business who will talk to you as long as it takes and not cut you short. Long story short he hooked me up with cam, lifters,springs, rocker shims( his own custom stuff) he had ran into before, head gaskets, dist, drive,pushrod help and and answered all my questions on anything, extremely smart and helpful. long story short he said I would be around 600hp and guess what 583 with a little left on the table because of time, pretty close wouldn it. any way thanks to Mike would recommend him to anyone:thumbup::thumbup::thumbup::thumbup::thumbup:
