I have no clue yet if it a roller or not yet. I did change it over to the standard non HO firing order. IT RUNS! it just donesn't run good when you put you foot in it. it idles perfect. just is a dog when you put you foot into it. feels like it missing but it not. I've checked plug wires MANY times. everything is good. It feels like a pinging motor, but its not. If anyone has a good HO block with heads still on it for cheap let me know. I also have everything from my 89HO motor on this one, injectors, all harness, fuel pressure reg. and I put a knock off edelbrock intake on it made for the 86-95 HO motors. I don't know if thats too much for it. Maybe it getting to much fuel, but I don't know without a wide band. This just sucks, lol
Ya the vacum line is hooked up to the map. Maybe there's something about the harness from a t bird and mustang thats keeping it from running right under power. I would just love to shove a stock motor in it a drive it for now.
