Or just run what you got now, work on the engine over summer and drop it in during the winter. Options are endless, however, I'd put it in once. To be safe, I'd atleast bust into it and see what is going on. Very worse case, run a compression test on the cylinders. I'v had one sbc have all great compression and on the #1 cylinder almost nothing, turned out it was a broken piston, so I tore it all down. Have a 235 that has the same problem, though I haven't figured out why it has no compression in one cylinder yet, didn't dig into it. So moral of all this is, its a great 5 min test that will tell you alot. But I'd just tear it all down, too much hassle if something IS not up to snuff with it.
