how much time in a 1/4 mile would stock LS motor with b16 cable tranny would most likely make?
depends on weight,driver lots of things! I ran a 15.2 on my LS, all it has is a intake and 7lb flywheel. It’s a RS so it’s the lightest, runs where with full interior and weight! Also still have the LS trans in the car, so I would imagine you could run a high 14.9 or 14.8 with a b16 trans.
i have an LS model with full interior, and some 16" rota gt3’s (40 series tires)… plus im a beginner 
on what rpm should i launch at the track?
thats for you to decide, i go at about 3900-4k with my ls but it also depends on what tires you have and how sticky the track is
oh ok. ill figure it out… would running wit 16" rims be ok? or should i use my steelies…?
uhm… any wheels will do. its like ur asking should i use 93 gas? or 87? the difference will be minimal.
ic. ill let you guys know how i did. thanks guys!
