excuse the lowercase, my hand is broken. the shop that built the motor recomended using only conventional oil, no syn. they suggested rotella 15-40 for the break in and then 2 oil changes after that bc of the good additive pack it has. i was thinking valvoline vr1 10-30. what do you guys think?

You could use Rotella Syn 5W40 after the first oil change-it's a stout oil. Mobil 1 0W40 is another good choice.

The shop does not recommend syn oil because they want to sell you an engine sooner.;) Break in on dino then use whatever oil you want. VR-1 is dino oil correct? If it was me I would run a syn oil regardless of what the shop said.

I agree 100% the shop builds engines and not oil. I would run synthetic also from the start. A 402 GM, Ford, Pontiac, Buick, Olds, Honda? does it have a roller cam or flat tappet camshaft? If you dont know for certain then I dont know what to tell you. many many people buy built engines but really dont know how to maintain them. Amsoil makes a 10w40 oil that is a High Performance oil with the proper additives for flat tappet engines. I use this oil in my 351W with a solid lift cam and it works very well. I will not change this oil for the life of the engine from previous experiences with this oil.

Show me a 402 Honda and I'll eat a head gasket with no ketchup.

It's two punched Honda V6. One on the front and one on the back. Sorta like a Citation with a Fiero back end.

I love how the whole engine is mounted past the front wheel centerline
