Comp 294s or bigger might be needed have to cc the heads and crunch the numbers. But it is Possible.
Pop ups are usally a little more detonation resistence. With a good squish band it should be ok. I think sunco 94 would be the most you would need with a proper tune.
87 octane is out of the questioon im sure.
pop up have less detonation resistance. And if you make it rich enough and pull out enough timing it'll run fine but it'll be down about 50hp. loading plays a big factor as well, a 4.56 rear in a light car like a pinto with a high stall and it'll be fine even with an optimal tune for power.
