The car runs great for what it is 10.20 @ 130 in decent air but I would like to run 10.0X consistantly and at least dip into the 9s occationally. The car right now is traction limited it seems to make a ton of low end and not much on top. I broke the rear gear last year and switched to a lightweight oneh(hence the weird 4.22 ratio). Prior to breaking I ran a 4.10 and a 28" tire, the .12 ratio change was enough to slow the car .1 in the 1/4 I then went to the 29" tire and it picked the tenth back up. I tried a similar cam (same duration @ .050 but 2 deg smaller advertized with a 110 Lc installed at 105) but it made the car a complete dog and it slowed over a tenth. A couple seasons ago I cracked a block and replaced it with another stock block that we did a partial fill on. This new block had an issue with the cam bearing bores being too small so the cam bearing outer diamiters were "polished" so they would fit. The new block has oil pressure issues, it is good when cold 40-50psi @ idle but drops to less than 15psi hot and only about 60 psi @ 7000. this is with Mobil 1 15w50 a high volume pump wich my machinist shimed the spring on to bump the pressure (made no difference over the unshimmed HV pump) All the bearings were fitted by the machine shop. I dont remember specifics but it does have .001" over bearings on both sides to tighten things up into spec. The lower end has about 400 passes on it now and is smoking a little so it will come down for a freshen up this winter. I want to fix the oil pressure issue and maybe make some changes to gain some power. Sorry about the long rambling post, thanks in advance for any suggestions.
