What should be my total timing I am building a ls2 carb race motor ,11.1 compression ,will be sprayed,has 58 tooth on the crank using 6012 msd box,what is usably the total timing set up on motor no nitrous just on motor.my sbc and bbc motors ran good between 35 to 40 degree on motor ,is ls motors different????

ls3 engines will make best power close to 30 but won't last that long at that. We run 28 deg and WOT for periods of 40 min straight on Av gas or 26 on premium at 2000ft. Anymore and the pistons go bye bye.

You got a carb'ed LS motor? Don't bother giving advice if you don't, cause you're just rehashing someone else's cr@p. I do have a carb'ed LS motor, and it does like 36° "mechanical". I also have another 14° "vacuum" advance added by a MAP sensor for 50° total. FYI, the longer manifold runners and relatively poor fuel atomization require more advance than an equivalent port injected engine.

You really should hang around in the carb forum where you'll hear from peeps who actually have experience...

Cheers yo. FYI, Fuel injection LS engines with that compression range anywhere from 18* to 23* with a clean setup at WOT, unless you are boosted. Trending Topics
