e21 motor swap project

It's definitely not a big block. I can tell just by looking at the xhaust manifold. This is a small block. Probably a 400CI.
Here's the difference:
small block, the 2 middle exhaust ports are toghether/really close

Big block, the ports are evenly spaced.

Not trying to be an asshole, just clarifying. None the less this is a cool build.
I'm also a chevy guy. I owned a 1976 Chevy C10 stepside with a 406CI stroker motor. prostock cams, built up valvetrain, billet crank, custom cam, etc.
In for this though

I am aware of all these things. I build engines for a living and have worked in an engine shop for ten years. It is not a Chevy. What you are saying about Chevy small and big blocks is correct. It is a gm and the brand of gm it is, it is considered a big block. I chose this because of the downward facing exhaust ports.

Gm/Chevy= practically the exact same.. Comes out of the same factory
Agreed. Same basic design but this motor came out of a pontiac. Chevy and pontiac don't use the same motors. It is a big block pontiac. The head design is completely different.

I work at an engine shop so a big block was kind of a shoe in
I restate this again.

Earl, you can restate your same comment all you want. But when most people say a GM/GENERAL MOTORS "big block V8" Everyone goes, GMC/CHEVY. The pontiac route is rarely gone over. So yeah, I'll accept I was wrong. But just because he's done motors for 10 years, doesn't mean he's always right.
An anyone from the SBC/BBC area could have made the same mistake I did. Because that's what most GM SBC's look like.

thats why I chose this motor. Super rare. Never been done, torque out of the ass, and the downward facing exhaust was Perfect for this car.

i had a slight freak out saturday morning and wasnt happy the direction i was taking.....so i dismantled the whole front end again and started over on the engine bay. In the 16 hours i put in this weekend i am 1000% happier with the results so far. it will be on the next level where i felt i was rushing and slacking before.
