like i said, it was a quick walk through summit. genIII is NOT where the bang for the buck is, sorry

first off, IIRC those are brodix 220cc 18° heads, which require pistons fly cut for 18° valves and require custom headers as i dont know of any production headers designed for a car that will fit their exhaust ports. of course i could be wrong and knowing summit they used the same pic for the 23° heads as the 18° heads.
lets use 3rd gen fbodies seeing as though they came from the factory with gen 1 small blocks. that way we get an accurate comparison. first off, a perfectly running L98 fbody with a t56 swap will not get near the gas mileage of an ls1/t56 combo. period. the LS1 is much more efficient. secondly, not only is the cam tiny, the intake sucks but the heads suck as well. most dont run huge cams though in their cars but a typical heads and cam L98 is lucky to break into the 11s even with a stalled auto. IMO you need more displacement with the SBC to even begin to make up for the less efficient engine. finally bang for the buck. SBC prices really arent much cheaper if you go for an apples to apples comparison. you cant compare a carbed SBC to an EFI ls1. not all SBC's were carbed bro.
and there is no way you can tap a carbed intake and add injectors, lines, pump, rails and intake track for 300 bucks. hell you cant even get a new carb intake for that little. not a good one anyway.
