it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
what are you calling a bolt boss? I'm not arguing, just trying to figure out what your talking about.
its where the vettes motor mount bolts to. most Gen III motors have 4 bosses on each side the vettes have 6

The iron motor will bolt right up in a C5. The LS1/6 blocks have 6 mount holes on the driverside and 5 mount holes on the passenger side. It still just uses the front 4 holes like a iron block. The other holes are used for grounds. I've done a couple of these swaps. I have a C5Z in the shop now that just got a 408.
Just the ls1 in the vette no power runs fine no smoke or anything just not enough like an ls1 should be. Also got the engine in the truck brealy finished and never really use it. Use my F-250 more for pulling and stuff. Just want the vette to be my dd with good amount of power. Thanks so by the sounds of it it should fit then.

Guess I just dont understand why anyone would want the extra weight of the iron block when you have an alum LS1 already in place. Its just as easy to mod as the 5.3 was. Do some of the same mods and you will get much better gains IMO.

By the time you pull both motors and swap everything over and install them back into the vehicles you will have spent a month of Sundays with time gone by with neither vehicle running, and not to mention the small fortune in fluids and gaskets that will need to be re-placed, don't forget to factor in the cost of re-tuning both vehicles for proper drive ability. Just mod the motor you have till it blows it up or breaks lol.... or you can install cheap HP on it. Serious doses of N2o till it croaks, then swap motors JMO
You would only pack on another 30 lbs overall I think as well from swapping an aluminum block to iron block...either way it's really no big deal...Just saying
