If you was to price out all the pieces and parts to build it all from scratch you would be up there, I think its a good bang for the buck. I'll have more in mine than a 120R would have cost when I'm done, and I'm trying to watch my pennies.

Having recently completed a 117, I totally agree. I think the cost might be closer than it appears to do all the things I did - but I think the 120R is a lotta bang for the buck and a great foundation.

Aside from the above, things I would address on the 120 R include:

heads touched up a bit and compression bumped for better mid-range punch
add roller rockers - HD put regular rockers in it...
plug and weld the crank -- put a 120 in and you're gonna run it at least a little. Why risk it?
Replace the JIMS lifters with better quality - S&S, Comp Cams, even Wood. Stroker Jim found his lifters were headed south after just 15,000 miles. Sounded like he JUST caught them in time...
add an oil cooler

Then, you also need an exhaust - 'zilla, Supertrapp, Wegner. Might want to consider a chain final drive if you twist it a lot.

Those are the things I would do, but then many folks are just bolting them in and running them.

I saw the pictures, hope it was an isolated incidnet.

Yep, or there will be some people with problems. Unfortunately, I've been hearing about a lot of JIMS quality problems over the last few years. Used to be a brand you could trust. Not so anymore.
