This year I took out the 4.11's and put in 4.56's which helped me realize my valve springs were junk. My original springs were 1.45 diameter with maybe 100lbs closed and 200 open. A co-worker of mine races stock eliminator he had a new set of comp 999 springs, a digital spring compressor and all the other tools to put them in. If I remember right these springs were 1.56 diameter which meant I had to get new spring cups, locks and retainers. On his recomdation I got Isky super 7's. All I can say is my pussy fingers were sore as hell buy the time we were done. Between the spring comressor and the height mique. We ended up just using the main spring, not using the inners. They measured at are @ 190 to 200lbs closed and 450 to 470 open. I was suprised how that changed the motor sound and how it changed the track times.
I think now its time for a set of ported heads and a single plane intake. I'm surprised you don't see any ported iron heads for sale...guys going over to aluminum. Idealy I would like to trade some of my stuff for a set of heads that flowed 270 to 280 but thats not likely to happen. So I need to start saving some money...
So heres some pics from last year with old springs and 4.11s
I don't know who put this video on youtube but I think it was from a race last june. That was a hotter than hell weekend staying over 100 most of the day.
