Check out the HD front sump parts poll in Best of Tech.I just can't get comfortable with the rear sump pan on a street car, but I'd really love to have a 3.75 stroke engine. Wish there was an elegent front sump / oil pump solution that would clear a long arm crank.
I've been working on an "elegant solution" for a long time but there's some realities that have prevented it from happening.
I've designed some parts (gerotor pump and shaft) that require tooling which would make them very expensive to produce in low volume and there is not enough demand for high volume production. Face it, if there was demand for good front sump pan somone would have already done it. The reason is the front sump is backwards for anything with a stong engine in it. Why build a big inch stroker if you can't nail the throttle for fear all the oil will slam away from the pickup.
I'm working on some new stuff that may be a compromise between pan capacity and ground clearance. The main thing is I don't want to lose performance so it won't be easy.
