You could try advancing the timing, with the modifications I wouldn't know what to set it at, but, you could try this, put it in gear with your foot an the brake...get it to rev at at about 2000 RPM and advance the timing until it starts to ping, then back the timing just a little...this is by no means the proper way to set your timing for your engine but, if it works than you know that timing was an issue. Questions like degreeing your cam and things like that I'm sure will come into play when the guys that know try and help.

As I mentioned earlier, if you have a vacuum advance distributor and have a vacuum leak it could cause this effect...even though your vacuum is in the green, you would need to check the vacuum going to your advance and if it is , is your advance working as it seems to give you the problem under load
