Sent my heads in to have them CNC'd. They look beautiful. Flow numbers were a big improvement over unported.
While the motor was out, I installed new bearings, Installed a windage tray, and had the motor line honed.
Other than that, I made no changes. Yesterday I went to the track and went slower than my times with the stock stealths.
Last year I ran (stock stealths)
1st run 12.84@ 104.43, 60' 1.782
2dr run 12.90@ 103.16, 60' 1.754
3rd run 12.80@ 103.95, 60' 1.761
Yesterday I ran (CNC ported stealths)
1st run 13.06@103.34, 60’ 1.847
2nd run 13.12@101.36, 60’ 1.846
505 stroker, stealths, full TTI exhaust, 830 quick fuel, perfromer RPM
Comp hydraulic roller XR280HR-10
2800 Stall
4767lbs race weight
3:23 gear with detroit locker
275/60/15 M&H racemaster drag radials
This is frustrating, anyone have any ideas?
UPDATE: Played around tonight, the trans is shifting weird. Its taking about 2-3 seconds between the 2-3 shift. I will mess with it to see if it was part or all of the problem.
