Standard volume pump.

X2 on pump

you guys have to think this is my 1st real motor build. i built my 4 banger years ago and it turned out ok but would have came apart if i would have ran it much longer. because the machine shop did not balance it and i did not know.and i have rebuilt a few chevys.:jester: but never have had this much just in a short block!!! i have read so much on this setup for the past 3 months i am about sick of it! but i have learned alot of good info and will share what i have learned with anyone. what is that saying 2 heads are smarter than 1! :nixon:

Good deal! :metal:

i seen the top of the rod bolt and some of the rod come up past the cam bearing and freaked:panic: i bet a 4 inch or 4.1 stroke is close!

I bet :jester:
I know a 4 is close, watched a friend assemble his. Another guy around here is running a 4.1 but it was done before I got to see it and I think he is running a small base circle cam.

Very close:banana:

X3. No need for a high volume unless you're running an oil cooler, turbo, etc, that needs it, otherwise you'll just create drag and windage. Take a standard volume pump, disassemble it all the way (including the freeze plug that holds the pressure spring in), clean up all the casting flash with a Dremel, or die grinder, and chamfer all the ports. When you put it back together, stack two 3/8" washers as shims in the freeze plug for the spring. That should give you about 80 psi oil pressure cold, and about that at cruising speed at operating temp.

How long before updated pics of homebrew. Lmao!
