I weld all my SD's and the M1knock offs and make them square bore. Have for years. On a 340 inch deal, under 7K the gains are usually 12-15 HP and the torque curve is flatter.
As the displacement, RPM or both go up, you need both plenum volume and shorter runners.
The gains can be even more impressive on the bigger RPM/displacement engines.
Haven't done a SV yet, but the Victor was a power loser every time I tried one over the SD/M1 that has been corrected.
One of my pipe drams is to find a decent used SD/M1 and modify it correctly for a TQ. I think that would be worth 8-10 HP over a Holley of equal air flow.
Maybe someday I'll test it.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Maybe someday I'll test it. Have you ever tried to make one of those intakes fit a 4500carb without an adaptor? Just somthing i have thought about from time to time but never tried or got around to even measure if there was enough material there.

Just somthing i have thought about from time to time but never tried or got around to even measure if there was enough material there. Funny this came up. I have two dominator a sitting here and I'd like to use one, but I don't want to change hoods. I was thinking about making a 1.5 inch thick aluminum plate that fit snugly around the outer sides of the plenum, welding it in there, and then making the dominator bolt on without the adapter. I just don't know it it's worth it if you can fit it all together with an adapter.
