Not Ranked
MOFO;
I used the exact same motor mounts on my Dart block (351) but when I tried to hook up the side pipes my header flanges and side pipe flanges were 1.5" apart and I couldn't bridge the gap. I'm running AFR 205 heads so the exhaust ports are a little higher than normal but most of it was from the mounts. I went back to a stock-type mount and that got the flanges much closer; I got the rest by SLOWLY tightening the flange bolts a little at a time over days. The first time I started it I was able to pull the hot pipes to fit. Not saying you'll have the same problem, but if you do...
