Good day today. Picked up a Rochester Carb and a new set of 374 pistons and pins for less than $100.
Now back to the grunt work

Ok, Here we go. I got the 374 up on the engine stand. The motor is frozen.
Popping off the lifter cover, the lifters and head has burnt oil, and discoloration on a lot of pats, so this engine has seen heat. I found a couple things that seem odd to me. The 374 was cast 12-1-55 and is stamped 5680. This Engine has ADJUSTABLE push rods, where my other engine build 1 month later stamped 1-20-56 does not. My understanding was that all 56 has solid push rods and fixed (integral guides) The other odd thing is that one of the push rods on Cylinder 7 has a larger ball and lock nut than all the others. so, should the rods be adjustable or solid for a 56 374? was there a running change ? Cornfused at the moment. I will get further into the heads tomorrow.

Packard did not build their V8s with adjustable pushups so obviously the engine is no virgin.

Oh Boy, this is NOT encouraging. Hopefully, I can work her back to spec. Have to really get into her to find out what has been modified.

Very interesting. Adj pushrods = solid lifters most likely (but not necessarily).

When u get into the rod bearings record any numbers that maybe stamped on the backside of the rod bearing. Ditto for mains and cam bearings .

will Do. I will get into it more tomorrow. I am on hold on the Frame until the rest of my suspension parts come back from Sand Blasting.
