This is just for the street right now. Car shows and stuff. I'm building a second block with 8.5-1 slugs and chromoly rods. May go with 4 bolt mains. This one is an .060" over 341 at 352 cubes. 10-1 Venolias with Hilborns, T3/T4 Garrets, 282 X .475" Contrerras roller, Megasquirt 2-V3 system, 727 with 3000 Hughes, intercooled, 72 lb injection for E85, 3.91 sure grip 8-3/4". I made a silicone mold and had the timing cover cast at a local foundry. It accepts the 318-340 water pump. I don't have a whole lot of money in it since I have made many of the parts myself. Thank you all for the compliments. Hope to make it to a car show by the end of the year. Bill
