My 352 was iron LQ4 block with AFR heads with 1/2 head bolts and 32 pounds of boost. It went 6.86@205 pushing under a quart of water per run! We have so much better parts now!!

Yes, but not for much longer I suspect. It will probably stay the fastest on 4 bolt heads forever since it would be silly these days to build a 4 bolt for extreme cars with all the nice 6 bolt stuff we have available.

I have a customer that has gone 5.54 @ 127 on mildly ported 317s on a 370 in a fox body. I believe he has some more left in it but ran out of time this year before the tracks closed around here.
