I'm stuck on nothing. I like the roller so I don't have to worry about all the junk with oil. I just read Grumpy's post on oil systems- they came up with a tool to groove the lifter bores so they add some oil to the cam. Cool thing.
and no, I don't think for a minute it'll take 600 ft/lbs without breaking everything. I'm still in awe that after 38 years it's still got the original U-joints, halfshafts and differential.
But looking at all the numbers I still think 600+ @ 2000 would be a hoot. After all, this is not a daily driver- it's a toy to come out and drive when the sun is shining and I feel like playing around a bit. So with all that, I'm looking at getting the most bang for the buck, AND keeping reliability. find the best balance of HP/TQ, fun, and bling will be the trick.
