would you start at this same spot if using a 11.8:1 lq9 with 243 heads and a 228/232 .600/.600 110lsa cam. single plane intake.
id just run 10 or 15* at zero rpm, then 26* strait across from 500rpm to top rpm.
26* is a reasonably safe number to start with for an 11.8:1 motor
Dont put any timing ramps in your idle rpm area. If you want to improve driveability, add a couple degrees below the rpm where your tq converter stall's
Putting together a L33 for this swap. Stock type flat tops, 799 heads shaved 20 thousandths and the 13160r comp cam. 112+2 lsr. Bored 30 thousandths. Will have a 2 speed glide with a 2500 stall. 3.73 gears. Just curious what you all think I should set this at. First LS build.
i have a lq9 with asa cam, edelbrock performer rpm intake, holley 750 carb. in a 70 chevelle. was thinking of using following timing curve - 0-1000 16, 2000-24 and 3000 up 33. do i have to hook up map sensor?
I have a 403” stroker with AFR LS3 heads, 11.5:1, Super Vic, 1000cfm Prosystems 4150 e85 carb and a 248/258@.050 .650/.632 112+3. No MAP advance, and I ran 18* initial ramping up to 28* at 3000 on out. It ran pretty good, and did 5 test and tunes. Was starting to get popping through carb on cold starts. Just got an AFR gauge hooked up and got my idle mixture adjusted fine, but still getting the popping. Some people at the track said I should try pulling some initial timing. I tried 16* initial and didn’t see a difference starting. Kinda hard testing it under load with the crappy Pa winter weather. Any thoughts?
