As with anything there are issues. Nothing that can not be worked around. One unforseen issue will be things like timing chain gears. This is the guy building my 400 stroker:

If you find a 400 he can work out those issues for you though. There are 2 new heads to work from. One being CHI and the other being Edelbrock. CHI flow better at high rpm. At a lower rpm the edelbrock flow a minute better but very close. Tim is putting the CHI on mine but he ground the heads to get the airflow back up at the lower rpm. One issue with the heads is intake. You will beable to use other intakes with the edelbrock but only CHI intake with the CHI heads.

They say the engine webbing is weak if you want to run over 900hp and over 7-8000 rpm and needs to be re-enforced. I have heard guys say that is why they won't run that engine. I just thought you should know incase you plan on running your Pantera in a top fuel dragster class. LOL.
