Its tsp EHT .675 springs, shimmed to their specs. Nitrided LS7 rockers with trunion upgrade... nothing else works with these heads. I might end up with a larger .700 spring, but its not an overly radical cam lobe (LSL). That particular pull was the only one with that odd dip up top.

Wow, nice. You are inspireing me to follow through with my 429 project. It will be with cathedral port heads though. I hope you get your 9.9. Please post up when you get your Holley Highram. Can't decide on mani right now.

Please keep us posted on the Highram. I am very curious to see how much tq you loose. I am going to be putting a like sized motor in a TBSS so TQ is a must. The Holley is just so much cheaper than the FAST and looks so much better.

Tony is one of the best. He can work magic with a FAST intake. The only issue with dyno numbers only is that they don't tell the driving story. So your impressions of every day situations would be great too. I am guessing that you loose two or three inches of runner lenth with the Holley but I don't know what that will translate into as far as more power and less tq. I would love to see it hold it's own.

For sure get it tuned. Not a fair comparrison if not. I am looking at running a 3,600 stall but I am pushing around 4,800lbs vs. your 3,400. Just want to make the right decision and you have the closest build to what I want to do.
