Did they make a 350ci 390 hp motor in 1969 maybe lt1

"The LT-1 was the ultimate 350 cu in V8, becoming available in 1970. It used solid lifters, 11:1 compression, a high-performance camshaft, and a Holley four-barrel carburetor on a special aluminum intake to produce 370 hp and 380 lb·ft . It was available on the Corvette and Camaro Z28. Power was down in 1971 to 330 hp and 360 lb·ft with 9:1 compression, and again in 1972 (the last year of the LT-1, now rated using net, rather than gross, measurement) to 255 hp and 280 lb·ft"

what he said, there was a 427 /390 hp but never 350
