360 LA installing Promaxx Aluminum heads
Went ahead and swapped out the plugs today to the 1 step cooler NGK BKR7E. Photos of the BKR6E below.. I snapped the porcelain on #4 taking it out... dunno how. I don't think I've ever done that before. So now I have my victim to cut open later. If the porcelain tip on #1 looks a bit darker its because I hit the threads with a brass brush and dirtied it.
Verified timing at 11-12 initial. Had some issues with my Snap on timing light so I could not verify total mechanical advance. IIRC that puts me at 35-36 total.
Vacuum sitting steady at 10-11 inches idle.
So the cooler plugs are in and she's hummin'. Tooled it around town for about an hour mixed driving. Got on the highway uphill and leaned into the throttle just a lil bit.. looked down at the spedo and I'm at 105. :steering:
Readout on the AFR is a hair leaner than last night. Could just be time of day.. about 20 degrees cooler today. Need more saddle time to collect data. Seat of pantelones says this rig is dialed in pretty nice. No stumble and power seems really good through the band. I'm really tempted to stand pat as-is. Lots of nice cars on the streets.. Hot August Nights started yesterday and I wanna drive... lol.
