So as some of you know Im building a 84 Hurst and 83 Regal pretty much simultaneously. So I was gonna put the 403 into the Buick but that just wouldnt be right. So last week I stumble across a Buick 350 2bbl and th350. I got them home and decided to open the motor up just to see what I was working with and what do I find???? Texas Tea, GOLD son.
