Engine noise

I have a 1954 Chevy truck. It has a 6 cyl.250 engine. It also has an automatic transmission. Whenever I take off and give a good amount of gas there is a loud screeching sound and not a lot of power. Once it gets going it goes away. Few mechanics can't figure out what it is. It's not a belt issue, already ruled that out.1 mechanic said it sound like a metal scraping sound. Any ideas?

If the engine is roaring while the vehicle is not accelerating as fast as expected, that could mean a problem with the transmission, especially the torque converter.

250? 235 was original or it could be the 218 which had no oil pump.

Could you confirm please?

It doesn't have the original 235 in it. It got changed to a 250.
