Mess of questions...

[Daks]

I am in the middle of performing a swap to big block in my 72 Cheyenne K20 with little to no knowledge on what this really takes to accomplish...

As I understand it from everything I have been able to gleen from the boards here is I need to move the entire drive train forward a little bit in order to gain the clearance that I need to make things fit. Well, I have a couple options and questions that I was hoping someone might be able to give some insite into...

I have an trade out where I can get a 700R4 tranny for a littlle side work that is being completely rebuilt and was thinking about using it for the overdrive. As I understand it, the 700R4 is about 2" longer then a TH350. Can I just bolt that 700R4 directly to my np205, use the 2" in lenght difference to place my engine far enough out front to clear everything without making a headache (or more of a headache as I have learned...) with headers? Or do I need to change the shafts and get spacers and mess with drive shafts and all of that... At one point, I saw a decent thread that had some info on a 700R4 in a 4x4 truck, but I can find it anylonger... Also, does this mean that I have to move the engine stands farther forward as well to make this work? Or mess with any of the cross members?

If I stay with my TH350, do I need to do anything besides moving things forward a little bit? I do not really want to mess with changing the sizes on the drive shafts... And I definitely do not want to be beating in the firewall to get this to work.

You have to forgive me, I really know very little about engines, and working on any automobile, but I tell you... this working in the grease, barking your nuckles, and trying to figure out what the hell your doing is the most fun I have had in a long long time. =) Any help and insight would be greatly appreciated.

Thanks!
