Thanks everyone, I appreciate all the replies. Every time I think I have my mind made up, a new reply is written and my response is, yeah, he's right, that's what I'm gonna do, screw the cost. Then reality sets in, The 400 I have now has already been fitted into the car, the wayne due front clip has already been powder coated, car has been final wet sanded and I'm painting this weekend I hope. The currie rearend by DSE has 3.08 gears and would have to be changed if I went with an LS, (tunnel mods, motor mount mods etc.?). As much as I'd like to put in an LS because of reliability, gas economy, horse power and so on, there's as many reasons to stay with the 400 and the biggest one is I need to get the car finished, it's all I think about these days. The change would feel like I'm going backwards and with all the new products that come out weekly, I could make changes that would last a life time and never be finished. So as of now, I'm going to put some more dinero into the already rebuilt 400 and go with it. I'm open to suggestions on what all to do to it. Who knows, maybe tomorrow I'll change my mind again

Thanks again
