thanks for the info - much appreciated. i take your points and will apply them and double check the timing and also the primary throttle blades are closed .
thanks for the link to the carb spec sheets.
its hard for me to work out what jets i should have as they dont list it for a application but only for a specific carb model or part number.
so with a 351w with 30 thou over bore and this supercharger and with 2x 600 vac sec holleys. is there a close idea of what jets i should be using ?
i have seen around .62 for fronts and i have .72 but also have 2 carbs. so do i go lower as i have 2x carbs ? ie 2x lower than .62
very confusing and i want to get it somewhere there before going to dyno etc. i am sure with a bit of help and advise i should be able to get it to idle and run fairly normal. under small load before going on the road
also you say to lock the timing out etc. i havent got a dizzy. i have a ecu with a chart that i am able to enter actual timing numbers into. so for example what timing would you advise on the following rpm's ?
as i can put any figure against those rpm's but i can also go above the scale and add differnt figures for engine load. so ie 10% engine load could be 28 btdc but at the same rpm with engine load at 70% that wouldnt be the same figure ?
