Timing Question

[KellyTurbo]

HI,my brother and i build a buick turbo t clone with a 350 chevy. the motor is basically stock, stock crank, cam and heads.the mods. are roller rockers, intake ,MSD ing,dist.and BTM.stock style fullfloat rods and forged pistons.the carb. is a holley 750 mod for turbo setup.got a diesel turbo turbine, IC,home made headers,3.42gears,700r4 trans. so my question is ,what timing curve i have to run for this setup? thanx

Start with 30 -34 base and see what it likes.

93 or race gas?

You'll want to pull it down into the 15-18* range at 15# of boost on pump gas. Start low and see what happens.

HI,We do the timing change, at 28* work great good power,but the MSD dist have a 20*advance in timing.Ive been working with the MSD internals to low the advance to 15*cause the engine dont like the 8*at stall.
