Race weight this time was 3525. I think it has some 11.0hs in it as it sits. Didn't run with rear 15s and 275/50s yet, hopefully I will go tomorrow with those on.

I could prob get a fast 90/90 set up but I'm not sure if I will see any gain from it. I know if I do I need to get some injectors too. Also I could prob ditch that crappy merge on the pacesetter ory and pick up couple ponys and maybe some ft-lb of tq.

If you don't mind me asking whats your 1/8th et and mph? I thinking I'm going to have to pull off a high 6.8 to low 6.9s to get a 10sec slip.

Also going to be throwing some 4.10s in. So maybe I can pick up little from that too.



I did change the valve springs and pushrods to work with the cam other than that the heads are 100% stock.I wish I could mill them,also would get them ported at the same time but I know the piston to valve clearance is all ready close. So there would be no point taking them off unless to change them for some aftermarket cnc heads.

A good running N/A car will normally see 25mph between the 1/8th and the 1/4 mile. My first 10 second pass I went 10.995@122.8mph with a 1.49 60ft
