I haven't done much on the car lately, but back problems are indeed a pain. So, I bought some more stuff just to keep busy. I ordered a 351 Level 20 roller block from DSS Racing. I also ordered their main support. I had the DSS 347 short block in the 64 and it did a good job on the street and racing. So, after talking to them they recommended this block for the stroker 427 I am going to install. D.S.S.
