Except that engine building (properly) is a labor intensive industry.  Who do you think does all the measuring and machining?  Little engine shop fairies?  Not to mention assembly, mock up and parts fitting.

At Woody's level you are not just paying for his labor but for his skill set as well.

You get to ONLY have TWO of the following -- cheap, fast, dependable.

IOW -- if it is fast and dependable it will NOT be cheap.  If it is fast and cheap it WON'T be dependable.  If it is cheap and dependable it will NOT be fast!

Thanks FordStrokers 408W, Westminster Performance Transmission (W.P.T.) transmissions, TCS Performance converters, Broader Performance valvebodies and last but not least a BIG thanks (always) to my friends here and abroad in the World!

Based on the 2nd. one.... a little too high on the heel. Pinion needs to be placed "deeper" in the housing.... or reduce pinion shim thickness.... or as the 2nd. diagram below.
