What will this run?

hey guys. Took my 69 Dart out for its first outing at the track last week.
3270 race weight
727
4500 convertor, 4.10 gear, 28 inch tall tire
Stock 360 short block, about 9.5 compression, replacent sealed power flattop pistons, 27 in the hole
M1 single plane. My 950 carb that is tried and true, nice piece. Also tried a 750 didnt work as good
Comp 294 s solid cam 248/248 525 lift 110 lsa installed at 106
Eddie heads stock, unported
Car ran 12.17. Pulled the motor apart to see what it was afterwords, so now have the above info about it i posted above
Changes........ moderate well done porting of the heads, probably a stage two type job, and milled them to get from 64cc to 57cc, thinner head gasket, from 51 to 28 thick.... this should move compression to about 10.6/7 to 1
New cam and springs. Cam is solid, 260-264@50 565/565 lift 106 lsa, installed at 102
Swapping Single plane M1 for eddie air gap intake. Also removed another 50 pounds of weight.
Any guesses on new ET?
Thanks
