Thanks. I was originally looking for something similar to what you have; I was going to do the 1000HP 427 thing on a TCI chassis, but I stumbled on this Roadster and after some back-and-forth thinking - the decision was made to leave it alone. I'm running an H & H Super Stroker Flathead. I do have a 383 stroker in my rock-crawler, Edelbrock Pro-flo, and lots of gears. The 383 stroker is a great engine. Like I said - there's a lot of room in those front fenders. Have you looked at the width of your axle to see if maybe it's pushed the wheels too close to the outside edge of the fenders? I could give you the kingpin to kingpin measurement of mine. I could probably figure the center of spindle to bottom of the fender arc as well.
