So I have a stock block 383 using two foggers a 32 and a 24 jet. I am looking to upgrade my block and gain some cubes. I can get a smoking deal on a Bowtie Block and make a 421 out of it. Is this block any better than a stock block? It has 350 mains and Billet caps. Is a Dart block that much better. I am trying to get in the 5.50 range, I am close now, but feel I will need the cubes and maybe spray it a little harder. Thanks for the input.
