Post sbc timing questions.

I've got a 305sbc that we bult afew month's ago
here's the spec's... edelbrock performer intake
,edelbrock 600cfm carb,a reasonably bigcam,hei dist,t350 tranny 2k stall with b&m shift kit.also has 4.11 gears in the rearend

I was driving it around tonight and the thing is a dog out of the hole.You floor it from a dead stop it'll slowly climb up to second gear then it takes off great.but if you slowly ease your foot into it it'll take off better but not much.i've thought it was the timing but not really sure if i remember its advanced to about 10.

anyone got any ideas??the fact that my dads stock 98 stang can beat me is startig to piss off. <img src="graemlins/crash.gif" border="0" alt="[crash]" />

how big is your cam?? with a big cam you have less low end power and torque, so you may have to go to a higher stall speed with your converter toget your engine into its power curve.also check your timing and install a mechanical advance recurve kit.

did the problem just appear or has it been like this since from the beginning.

If it just started, check timing, valves, dist. cap, wires, plugs etc.

If it's been like this from the beginning I would say your cam may be wrong. What type of cam is it?

I had a similar problem. I connected the vacuum advance hose to the 'Ported' connection on the carb as was suggested by the carb manufacturer. I switched the hose to the 'Full vacuum' connection and the problem was solved.

You may also need more intial advance. Look for 36-38 degrees 'total' advance around 2500-3000 RPM with the vacuum advance hose disconnected and plugged when setting the timing. Re-connect it after you have set the timing.
