@shomethe$$$ I can appreciate where your comming from.......I think. Even if your aproach is little negative twords a guy who is just building what he wants for his own reasons. Not all our reasons are the same for what we build. No need to attack his or his mentors intelect.
Think about it for a second. He is one of us! Not only is he a car guy, but he is a car guy that likes to do his own work, and then at that, he's a guy that is willing, to do a crazy swap with a motor that is not an easy motor to work with! There's not alot of guys like us. I say we all help each other as much as possible...
I think thats what your tring to do right? Your way of helping a guy out is to make sure he knows there are much better options then a SHO, correct? I 100% agree with you by the way, but I'm pretty sure he understood that a long time ago as well. For his own reasons he has decided to move forward with his project, I get that, so I will support him as much as I can.
I'm sure if he does it right he can work around all the issues you have mentioned. Weight is not the problem, so long as the parts being used are rated correctly. Setup however is all about balance and making sure everything works together as a package. From RPM range, gearing, dampening, braking, alignment and so on.... Anything can be built and made to work, will it be optimal with a SHO in it? No! Not at all!!! But that's not the point is it? At least not for everyone all the time.
Your spot on about weight of the motor vs. performance vs. cost and all that, I am actually having to do some serious soul searching about what I want out of my own project and I'm deffinatly leaning away from the SHO. Opting instead for the lighter, more powerful, more durable, more available and more affordable Duratec 3.7 for all the reasons you previously mentioned. BUT, only because I want a track day car with a license plate. However it is very hard to give up on the SHO. I just love that engine, even if it doesn't make any sense, it's just cool.
To each his own.
Don't give up on your SHO
@Hambler. Build what you want and have fun. It goes without saying to make sure it is safe above all, but I'm sure you didn't need us to tell you that.... or anything else for that matter. Sounds like you are on the right track and doing just fine.
