Shortblock assembly suggestions?

920 Views 3 Replies 4 Participants Last post by  n2omike
Next weekend I will be putting together the shortblock of the 306 I have been piecing together. Just a few questions about measurements and assembly.

1. Assembly lube? Is it necessary or should I just use oil? If so what kind? If not where should I pick up assembly lube?

2. Rod bolt stretch? I do not have a guage, can calipers been used instead to measure?

3. What is the best way to install the pistons, last time I just coated all the cylinders with oil before installing them.

4. What is the proper torque on the oil pump bolts and oil pump pickup bolts?

5. What should the endplay read on the cam?


other than that I should be able to get most of the information I need from the tech articles. If you have any suggesstions please let me know.

I like BG assembly lube, I get it at a real local auto parts store, you should be able to find it. I've built plenty of engines with a good torque wrench, just remember to put some good lube under the bolts or nuts. Read the directions in the ring package a see what is recommended for the rings, some call for lube and others do not. I believe the oil pump bolt is 7/16", so torque it to 65 lbs. The pickup bolts are 5/16" so go 19-20 lbs.
Oil pump is 23-28# and it's a 3/8" fastener.

Personally I use SAE 30 non detergent oil when I assemble an engine. Others swear by GM's EOS.
1. Assembly lube? Is it necessary or should I just use oil? If so what kind? If not where should I pick up assembly lube?
Yes. I like Redline Assembly Lube. It has a 'gel' consistency, and can be used on every part of the engine.... minus the cylinder walls.

2. Rod bolt stretch? I do not have a guage, can calipers been used instead to measure?
Don't fool with stretch. Simply torque them to whatever specs the rod bolt manufacturer recommends.

3. What is the best way to install the pistons, last time I just coated all the cylinders with oil before installing them.
I like to coat the cylinders with 2-cycle oil, as it is designed to burn away cleanly, but motor oil works just fine. Just don't DUNK the pistons in oil before installation. It will carbon up the ring grooves.

4. What is the proper torque on the oil pump bolts and oil pump pickup bolts?
If I'm not mistaken, it's around 22ft-lbs. However, you might want to double check that. An excellent reference is "How to Rebuild Small Block Ford Engines". The author is Tom Monroe.

5. What should the endplay read on the cam?
That will also be in the book, but I believe it is around 0.004" to 0.010" or something like that. Do this with the cam retaining plate installed.

other than that I should be able to get most of the information I need from the tech articles. If you have any suggesstions please let me know.
Buy the "How to Rebuild Small Block Ford Engines" book by Tom Monroe. It will give you PLENTY of good reading!
