Actually I chose that cam because it was "close" to the specs of an
RV cam I had in a 283 many years ago - that cam ended up in a 305 and I
loved it . This one was listed as a "stage 3 camshaft" , and I listened
to several sbc motors using a cam with identical specs (Summit 1103)
before I bought it .

The bolt on my motor mounts goes thru metal on both parts , not
worried about tearing them up . As far as swapping this cam out , I
don't think I want to do that ... OK so it's a bit "hotter" than I meant
it to be , but I don't see that as a great big problem . If this was a
daily driver to and from work I might be more concerned , but this truck
is going to be a toy . We got along just fine with one car and the
motorcycles for 5 years so ...
And ya know the best part ? My wife understands ! Sure , she's made a
couple of comments on how much I've spent , but never with any animosity
or saying I've gone too far . I think I'll keep her ... (Married 49
years in August)

Today I finished taking the trans apart on the Ultra , and it's not
as bad as I thought it might be since I basically ran the poor thing out
of oil . The main drive gear will be replaced along with the
countershaft gear , everything else seems to be OK . No signs of galling
or other damage on any of the other gears , all the needle bearings are
fine . The main drive gear bearing and the main and counter shaft
bearings on the other side will be replaced just because . Seals and
gaskets replaced a/n , the big seal on the MDG and the sprocket nut are
both on order from a shop in Little Rock (Rodney's Cycle House) . I'm
also replacing the comp sprocket , chain and clutch basket w/sprocket .
I figger when I get done the bike will be good for another 120,000 miles
. Not that I'll live that long , but I'm damn sure gonna try !
Just cracked a new bottle of COA de Jima Reposado ... this is some
damn smooth Terkillya for a mid price point ! If we drink this whole
handle , there's another in the cellar . Shirley pass out some glasses !
