It looks to me like it would be well suited to your engine combo and make great power. One generated 350 horsepower with a compression ratio of 10.25:1, and the other was a 375-horsepower engine with an 11:1 compression ratio. In any case, as mentioned, I would use the cam you already have and see how you like it. It runs pretty good, but now I want to get it to tow. PO said the engine was re-ringed and re bearinged and an RV cam added (again, no specs). It has a stout, freshly rebuilt TH400 with an Allison 6 bolt converter, 14B, but the original 454 was replaced by a 350 of unknown vintage and source. all the roller cam hardware needed is here. I just bought a smog exempt 75 3/4 ton for a tow rig. I will search craigslist or for a different year block. 1994-95 GM did stop drilling and tapping those provisions so I typically wont rebuild one of those motors. He says the stall is too low for this cam but he prefers it to running more converter, but his car runs 11-teens full-weight with a Goodmark steel cowl hood, shifting at 7000 RPM. 1987-93 blocks have all the roller cam provisions.
package, Super Vic, 830 annular 3800 stall and 4.56 gears in a '72 Camaro RS. A buddy of mine has the Crane #118521 244°/252° 112° LSA street roller in his 11.5:1 383 with AFR 210 heads with the Comp. And at that point if you stay roller you should be using a solid street roller. A 240° 0.050" cam is fairly big in a 383 and will require at least a 3500 stall. With an RPM intake and 750 vacuum secondary Holley like a 3310 the above combo should make for a stout street engine.
BC high performance camshafts are ground on state-of-the-art CNC cam grinders to insure accuracy and tolerances to within. That cam you already have looks great for what you are proposing in your spec sheet, to be honest. Developed to provide steady performance and reliability Made using up-to-date equipment and new technologies. The point here is to not get carried away with sticking too big a camshaft into a 383. As to a 383 cam, while you can run a bit more duration over a similar 350, it is not the same as camming a 400 which can really handle a lot of camshaft relative to the smaller engines, because it also has a huge bore (4.125"-4.185" depending on over-bore) and that also makes a big difference in cam specs.
