Hey, Listen…
Just beginning to install a 'fresh' (47 y/o) motor and remove my '68 170 in a bronk I've been running since '83.
My assembler started w/o me (he owes me as we have a barter arrangement - have been in this good relation for years) but I wanted to be there. Here's two reasons why (I trust him but wanna learn as I've never assembled an engine):
I have a '69 just machined. Got a head from FLA as I understood the larger log '77-plus would be more desirable. I seek tq only (@ low rev) - a lill different, most here seek HP as I don't want to spin tires (am in dirt most the time). Was shipped a '73 head (by casting #s) eventho I put the money down on a " '78 Fairmont". Anyway, I'll put it on unless I find a C9xx-6090-M as I just learned a very limited edition of the '69 - with the < M > - can be found. "Better runners for the low rev tq" I hear. Back Later with specs on parts ordered and machining particulars done.
So the 2 Qs I'll ask your assistance on (many more as the process unfolds I'm sure) if you'll permit, is about the cam. The machinist ordered all internal parts as well as machining it. It's a Comp Cam. My assembler partially assembled, and as he went, found binding w/ this cam (I believe at the bearings).
* He took it back to the machinist to B turned down "1 or 2 thousands" I believe he said.
* Also the ordered timing set when fitted had to be returned for another one & this one still is not right - I think he's going with the new chain and one of the sprockets (i.e. 1 old/1 new gear).
Seems like 2 unusual developments, no?
I want the '69 to '72 timing set as it's better for my tq goal and can't understand the cam bind. If I wasn't a newbie I might see that these 2 work around strategies are perfectly OK. I have confidence in both the assembler and machinist BUT you guys know these engines better than either of these 2 folks…
Thanks for lookin in & any comments you wish to offer.
