Crate replacement 5.7L TBI assembly problem.

[colbystephens]

I was intending to put the finishing touches on getting my long block fully assembled and installed into my truck today, but I ran into a snag. This long block came with these huge studs that stick out of the main bearing caps. They prevent me from getting my oil pan mounted up because they are ¼" too long to fit. I'm assuming it's for some other kind of oil pan with an engine-mounted baffle or something. Not sure what to do. I'm going to check with the engine builder on Monday to see what I should do. In the meantime, thoughts?

The engine has a 7 year, 100K mile warranty, so I'm not about to start switching over old internal components to make things fit up.

Also have a question about the lifters. Now, they ran this engine to test it, so I'm sure it's done correctly, but they're different than the ones that were stock in my truck. As you can see, these lifters stick out through the block, which indicates to me that they're longer and that the push rods are shorter than stock. What do you make of this?

Stock:

New:

The block may be a newer roller block but not machined for the roller cam. The roller lifters need a little hoo hah to keep them from spinning and a retainer to hold the hoo hah in place so the lifters are right but the lifter bore is shorter. As for the studs, not sure

Interesting.

Colby, those studs on the main caps are for a windage tray to bolt onto. Just remove the studded bolts from the new engine and replace them with your standard bolts from the old engine and torque those bolts to 70 ft/lbs.

Your original engine is a roller block whereas the replacement engine is not. Nothing to worry about as the lifters are the same height and the pushrods are the same length unless it had roller lifters (which it doesn't).

Good to know. I expect the engine builder to tell me to do the same thing regarding the studded bolts, but I am going to wait for their instruction before I go messing with possible warranty issues.

Yep best to ask the guy who will administer the warrenty for sure. He might want you to verify the torque on the bolts. I would if I was had a warrenty on something

Oh yah I concur ( like I need to now lol 4x4 high has got this lol) with everyone else
