Rusty bores

Re: Rusty bores

Joe R,

Silly thought...

You seem very convinced in going the 454 route despite the expense.

You might be best off buying a used 454 motor, and adding your intake and carb to it to make it "look" original. Oil up the bores of your current motor, bag it and set it aside. I suspect it might be cheaper.

Patrick,

I'm not really hard over on the 454 route. I'm just weighing my options and asking lots of questions. You're right, that would be another option. But I will probably use the block I have. I'm mostly interested in performance while maintaining a stock appearance.

Here's a short block if you wanted:

I think you'd get as much benefit from taking it apart and tanking it, then carefully cc'ing the heads, port matching it and doing a bit of head work. Far cheaper, that's for sure.

...however, this is a Gen VI block and will not be externally identical to a Mark IV. There may also be some compatibility issues using Mark IV heads. All-in-all, though, this is an excellent shortblock.

If Mark IV head would fit, I suspect a little orange paint and no one will know the difference.

That plastic timing cover and configuration of the front of the block would give it away.

my 67 435 is fast, but my 03 zo6 will kick its butt with radio and air blasting away, but 67 way more fun

Re: Rusty bores

All,

I think I have returned to sanity. Well, maybe that's a bit of a stretch. Anyhow, I think I will stick with my 427 crank. I probably don't want to risk removing any metal from the block. Along the same vein, I was thinking about having a machine shop put larger exhaust valves in my 3873858 heads. But I don't think I really want to chance it. Thanks for all the advice!

Also, here's a link to another thread I started that is about engine storage. Maybe I should have just tacked this one onto it. Here it is:

I would not recommend having the valves enlarged in any head casting and installing valves which are larger than GM ever installed in that casting. Besides, for your engine, you would not gain enough, if anything, from such a change to even make it worthwhile.

Clem,

So that's the good stuff, eh? I assume you put it in the bores. Did you use it anywhere else?

i also used it on assembled engines by squirting it into the exhaust ports before plugging them.
