Thanks guys, I will try to answer your questions. Yes we sell the valve covers, the engine is close to a max effort for what it is, light crank and bob weight for a 588, trick ring pack and intake. If I did it all over there would be some changes for sure. Its going in the car next and I will tune it from there. For a 588 I don't think a TS or Predator is much better. I now wish I had used the 4.75 crank I have, but it would not fit with the 55mm cam. The heads flow 476 Intake and 330 Exhaust on our bench. We never touched the carbs, every pull the the break was moving a little and the vac. was going up as the rings were seating. Was not cheap to build and there was a lot of fab work for sure, but none of them are at this level. I changed the dry sump pulley already to lower the oil pressure also. Here is a picture of the car. Thanks again!
