Thanks for the questions! The two engines actually have a different head castings, both however retain the 87-95 TBI edelbrock tbi intake manifold. Since we aren't chasing 450 HP, we can retain the factory TBI setup with just a re-calibration, opposed to replacing injectors and pumps. The higher horse 315 version has a 64cc chamber world head vs an oem tbi type 68cc chamber on the 280. Without getting overly specific (which I would have to talk to engineering to do) They are not heavily modified, other than the middle 2 intake bolts on the 315 hp version.I've had a question about the heads on these engines. They are modified TBI heads, but what work exactly has been done to them?

They don't take much valve work or port modification to hit these power numbers, so without getting overly specific (which I would have to talk to engineering to do) They are not heavily modified.

Its no secret they aren't GM's best flowing head, but they will support the 280 horse version with minor work. The 315...we use the new/different casting, which is a big improvement over stock. It's more an improved design vs any extensive work.Thanks for responding! I have just wondered what work was done to the heads to get them to make more power than stock TBI heads.
