Thanks, we're trying to keep the fans happy.

Ron keep up the work. My parts area looks like yours. I have rows and rows of tried and failed parts. And the different motors, the 2.3 is just as bad.

Man, Ford is bad with parts. I just was reading through some of my info last night and Ford had used, up to 2001, ten different blocks for the 3.8. The variations are slight and mean little (other than the FWD/RWD distinction) but can create headaches for building engines and using parts on hand.

The 1999+ split port 3.8L engine is one hell of a motor. We got one yesterday and disassembled it to have a look at what it is all about. Mostly it is the same as the 3.8L single port motors like we have, but the heads on this engine can really breathe. They have two intake ports and larger valves to boot. The exhaust ports are tiny, but, they are way undersized for the gasket and unless the water jacket is a problem they could be improved even under IT rules. The motors are internally balanced therefore the crank is different than our engines.





Six intake ports, three cylinders. We're going to keep the parts around for the possibility of building an ITE motor for the stang we have, or maybe one day building an ITR car. Anyhow, for ITR I think these motors could really put down some power. They are rated at 190hp from the factory but they would see significant gains with a proper IT build. However, my main reason to purchase it didn't pan out so well. I wanted the windage tray from this engine since the 94-99 units are NLA from Ford and we're out of them. But, this motor is a 2001 and Ford decided to change the windage tray unit to be a stud girdle/windage tray that I can't use. At least the front cover was the same though and I can use that. Front covers are fragile and we've a pile of cracked ones.

Ron come to one of the race weekends and you can have a drive of the Mustang on a test day or race. I think you'd find it to be like your ITB car, just with a little more power. After all the underpinnings are essentially the same, very honest handling and fun to drive.
