Give me some suggestions on a 300 build

I know there is TONS of information out there and I've been nosing around a lot but it's like trying to put together a giant puzzle, so figure I'll get it all in one thread.
 
Have 6 300's in my back yard right now.  3 2nd generations and 3 1st generations.  All need work.
 
I have 350D or 250TRX rear ends for all of them.
 
I'm putting BR timing chains (DID) and cam gears in all of them, and plan to use BR/ 250A cams in all of them.
 
Already have bored cylinders for them with new pistons.  Plan was to go through the motors, clean them out, put in new seals and timing chains, slap the new top ends on them, and run them with some 26's
 
I wasn't planning on doing anything too exciting, but I have a friend who is giving me a 54% gr and a swingarm stretch (yeah  I know, that's a helluva friend) so I'm thinking now I might want to go a little bigger with one of these.
 
So, it appears that about a 29.5-30 is the ideal tire for a 54%, right?  If I drop down to a 28 is that going to make the engine scream?  (I think the 18% is good for 27's and light 28's, right).
 
The stretch should work fine for that in the rear.  Can I do a bracket lift on the front or do I need to get the custom arched a-arms?
 
Lastly, should I build a 1st gen or 2nd gen? 
 
Initially I had planned on building the 3 2nd gens and fixing and selling the 1st gens (my buddies all want them for their kids).  Reason being, I want to run 424's on them, and the 2nd gen's seem to have a little more available in the way of parts, and the 424's don't have to be modified to work ($$$)
 
That said, I've seen somewhere that the 1st gen frames seem to make better mud bikes.  Is that so, and if it is, why?
 
I move VERY slowly, and I normally start hoarding parts long before I start a build, but trying to figure out what all I need to be watching for as far as tires, front lift, etc.

    Man you sound like me as I have a heard of 300's. I'd do the 54% with a fresh motor and 29.5 outlaws. As for as gen 1 to 2 everyone said a better mud bike for gen 1 cause the motor was a little hotter in those bikes. My buddy Whitney has built a many big lifted 300's and has never said one way or the other. You might want to body lift your frame as well.

    Yeah, I haven't actually torn into a 300 yet.  I have done 500's, 350's and 420's, and have a couple of 350 Foreman motors torn down I'm working on now. 
     
    I believe the only difference in Gen 1 and Gen 2-3 engines is the cam and the CDI.  Is that correct?  I plan on running BR cams and chains in all of these, and if I build a Gen 2 for a mud bike will put a Rick's CDI on it. 
     
    We do a lot more trail riding than mudding, so I'm not sure if I want to go 29.5 outlaws.  That will make for a brutal ride for miles to get to the mud.  That said, no point in building a mud bike if I'm going to get stuck on it.   I really like Mudbugs, but they only go to a 28, and I have a feeling 28's with a 54% will be screaming, right?

    The frames are a little different. The snorkel on some are built into the backbone and also the 2x4 had strut like suspension also. Yea a 54 isn't gonna get you know where fast and as the screaming part goes I guess it all depends on your thumbs. Hey as weird as the look the Interco sniper has a continuous lug pattern or the mamba lites as well. Man mudbugs is just suck a good all around tire and I too wish that came in larger sizes.
