I have done a lot of work on my Midget over the last 20 years, but some things
still are beyond my areas of knowledge.
I am having a friend assemble a rebuilt 1275 for me. He has done many.
The donor engine had excellent oil pressure, and there was no marks what so
ever on the crank, which had been turned for a prior rebuild. So the crank is
going in as is. I was advised to replace the bearings because they showed
some acid pitting due to sitting, so I am.
The block was from a different engine, so it has been hot tanked, oil
galleries cleaned, the deck surfaced, new cam bearings, and bored to match the
new pistons @ .0600 over.
The cam is also from the same engine as the crank, shows no scarring or
damage, and the lifters look fine. The exact specs are unknown, but it is a
mild performance cam of some kind, and I was happy with it in that engine. My
guess is it is something along the lines of a 256 grind.
The head is a new aluminum piece, new valves, new uprated springs, and a 1.5
roller rocker.
Questions:
1. I wasn't going to replace the oil pump, because the pressure in the donor
engine was fine, ie: 35 hot idle, 60 psi hot cruise, however, upon inspection,
I'm told it is slightly out of spec, and has light scoring. I've never had
oil pressure problems on any of my 1275's. Should I replace it?
2. I wasn't going to replace the head studs. I have a full set of dimpled
studs. The threads look excellent, but the shafts show varying degrees of
minor pitting. Should they be replaced. If so, stock, or ARP?
3. Fill in the blank, based on the above info, is there anything else that
should receive attention? I'm running out of money.
The car is used for pleasure driving only, about 3000 miles a year. Will have
the LCB header and DCOE Weber that are currently in my car, and runs out
through a Datsun 5 speed and 3.73 axle.
Thanks!
