Question Too Slow/Q-Jet question

As many know, I’m trying to put a stocker together in time to make Orlando. Went and tested today and everything went great! Car seemed happy, suspension was locked in, and the car was very consistent. Only issue is it’s too slow. Only managed an 8.20 off the NSA 8.26 index in pretty solid air after draining a quart of oil. I think it might be ok in Orlando but I know the car will lose time in the 1/4 vs the index in the 1/8th. I’m looking for more ways to speed it up, even if only a little bit. I’m told I could look into an M200 trans instead of my TH350 which I’m open to. Any input there would be great. Additionally, if there is anybody out there with a similar combo (‘80 305 Chevrolet) what are you guys running for jet size? My carb seems to have already been gone through and loved on as it idles great, launches well, and never misfires or stumbles. Honestly the plugs look good too but I’d still like to double check against why others are running. Mine currently has two 65 mains at 6.5 psi fuel pressure, I’m curious if that’s close to what others are running. Any helpful input would be welcomed, I really wanna go in 2 weeks but if I can’t go 13.00 I there’s really no point.
