Thanks guys, all good to know. I figured wheel bearings might be a bit of a thing cause of the weight of the car...

and the radiator has a pinhole leak in one corner so I don't know how to repair that effectively (JB weld apparently didn't work super great).

No oil cooler, anyone know of a cheapie I can pick up and plumb in ? I assume I should use a sandwich plate, but tell me if there's some more creative way. Suggestions on a place to buy?

I think I can keep the revs in check so I'm not super worried about valve float, "I'm gonna take it easy during this race"

Well... hmm... will check out the built motor, but I'm pretty sure it'll be out of my league at this point.

Thanks guys!
