Broke In New Motor Tonight!!! Tunig Q's??
Broke In New Motor Tonight!!! Tunig Q's??
The motor seems to have broken in pretty good, just wanted to ask you guys with stealth ram combos what fuel pressure/timing you are running. Ive got my fuel pressure at 45psi, and my timing is at 8* base. I know i can put more timing into it, but we were just breaking it in in the driveway, will take it for a drive tomorrow.
Motor combo is Stealth Ram, Adj. Rails, Accel 24#, MSD 6al, performer RPM 64cc heads, LT4 HotCam Kit, 350, .030 over, forged pistons, etc... just looking for some figures to compare to.......

my combo tends to like about a total of 23* of timing at full throttle. 10.3 compression with aluminum heads.... I'll send you my timing and fuel maps if your interested, they are in tunercats format. I added 3* timing to the lower maps and rpms without any knock, and feel i could add more., but i'm running a 224-230 cam which allows more timing in the low end

could you send me your timing and fuel maps? I havent got my car started yet. but I would rather have the first startup on a more "advanced" fuel curve as not to run too rich or lean. I will be running the CC 305 cam (220/230, .544/.544 114lsa) with a Lt1 Intake and stock 22 lb injectors (for now) on a 10.5:1 comp. 6" rod 355 with ported L98s
