331 Qs & Canton Oil pan / vert Qs

I need opinions.

I might/do have a chance at buying a brand new (never left the engine stand)built 331 for 6k-ish. It was built buy a local shop for a customer and now the shop has it (long story). Just wondering if you think it's a good deal and what power I can expect to produce. Here are the specs:

stock girdled machined block, 4340 crank and rods, JE flat top pistons (10:1 compression),Trick flow high port heads, TFS R intake, Trick flow stage 2 cam, crane 1.6 rockers. It also comes with 75 mm TB, 255lph in tank, 30lb injectors, 6al msd, Canton 7 qt oil pan, new water pump.

I know I could get a DSS long block for 5100, but this engines already built and includes a lot more.

The motor was built with a 200 shot in mind. So how long do you think the stock block would hold up to the nitrous? I won't spray til after I get a new tranny and rear end though.

What power do you think i could expect all motor? The shop is telling me over 400 at the wheels. But I don't think so. I agree with what other people have told me, more like 325-350. How long do you think the tranny and rear will hold up without beating on it?

Also, will the canton oil pan fit in a vert with the extra bracing?

No I'm not planning on a 200 shot. The guy that built it was telling me that's what it was built for, but I pretty much figured it would split the block. What do you think would be the largest shot I could safely run?

A girdled block can handle what 500-550 at the crank? or is that too high?

I don't know clearances or ring gap yet. I have to make a phone call and find out. I think the heads are the older iron ones, that's another question that's on my list. The engine was built to spin to about 6500. Everything that's listed above is what I can remember from talking to the guy the first time.

I'll find out more info. I'm just trying to weed out truth from some borderline BS that I think I was given.

So even if the heads are the newer aluminum ones, would you still consider it a weaker combo? Are the newer heads with the stage 2 a better setup? I really don't know a whole lot about trick flow.

I'm going to try and call the guy later this afternoon to get all the details.

Thanks a lot for your input, I appreciate it.

I do have smog inspection, so you're right that'd be an issue.

You raise a lot of good points and you're beginning to sway my opinion. So I might just hold off on it. I still need to find out more info about it. The fact that it is only a stock block does bother me. If I decide to pass on this, I guess I'll just start accumulating parts for a HCI swap
