Where to start?

So if I build a 318 300HP motor for my 40 ford pickup I will be fine on this thread but the early ford guys will be very critical I guess------------------
I personally don't like mixing brands. IF I had a 40 ford truck, she'd get a ford motor. But, when people do T-buckets, and Roadsters, and the such, put what ya want in it, cause nobody knows what it is anyways. But again, your car, your money, you da boss :D
