kgs365 You will be fine with either of the 2 bellhousing. Just ask Peter or Bob if the flywheel is SFI, that's all. Ask the weight too. See if the motor comes with a 22 pound flywheel. If this is the weight I see no problems ever. If the flywheel is a 40 pounder and SFI, I would ask you to limit rpms to 6,000. I am sure that the cobra bug for more power will bite you and down the road, you will want and need a bigger stick under the hood.
IMO I think that the SFI testing is better than no testing, but question how and what size flywheel is exploded in the bellhousing. Most FE motors run from 20 pound to 40 pound flywheels. I think this is why some people are so concerned. I was the one last year who started the same thing.
There is a side note on that exploding 557 boss motor. I believe that the guys didn't want to wait for a Billet aluminum flywheel and went with a cast one.I Under stand that this flywheel let loose at 7,100 rpms or higher. They where in a hurry to see big power and could have cost someone there life. The other STUPID thing was they wasted a rare boss block. I am sure they will have it welded back togeather. Question will be is the block still internally solid. Good luck with your car, looking forward to seeing it at ERA or one of the shows. Rick L.
