Here are a couple pictures of my Olds 403 under construction. It's been bored 0.030 over so it now displaces 409 cubic inches. I've gone for a fairly conservative build (1 bhp per cubic inch, hopefully a little more) so the engine will be reliable and will last a long long time. It's one thing to make good power. It's another thing to make it in a way that doesn't reduce the life of the block . . . that's another reason V8's rule.

I still haven't put the intake manifold on:

I won't be assembling the valvetrain until right before I put the engine back in the car. Otherwise, all the oil would just drip into the oil pan.

This project has been on the backburner for quite a while because of the accident and body work. Hopefully, I'll have the original 403 (now 409) back in the TA before Christmas.
