Well, this is the entire reason I am asking. I have a brand new engine, never taken it over 3k RPM. Never to the floor. I have 74's in the front for jets, 85's in the back, 32 shooter in the front 35 in back w/a 4.5 PV
I just got this combo to sit pretty at 12.5 AFR cruise, idle bounces between 12.2 and 12.9 or 13, usually rides in the 12.5ish zone. AFR Seemed to dive at 3,000 RPM on highway @ 65-70 mph though. I think I have my secondaries opening too soon. I have no idea what the EGT top end will be, but I don't want to burn a brand new valve, on a brand new motor that I have been waiting 3 years to drive. A calculator said 120mph is at 5,200 RPM in 3rd. 3:23 gears w/24" tires. I need to be careful taking it up to top end. Just broke it in about a month ago, the diff was broken in about 2 weeks ago. I am waiting on an 800hp rated driveshaft, had to save $$ for it. But could possibly get it this week. Everything is new. Trans too, but only a 2,500 stall.
