Ripping it all out. Will the new engine work?

I'm removing the 350 TBI in my 91 Camaro. I'm wanting to replace it with a Blue Print 383, 430hp FAST EZ-EFI crate seen here: http://blueprintengines.com/index.ph...83-bp38313ctf1

I'll also be putting in a Performabuilt Level 1 700R4 seen here: http://performabuilt.com/level-1.html

Now the crate engine doesn't have EGR. So the question is, without the EGR, do I need to keep to rest of the smog stuff to pass emissions? I'm still running cats and I would think that the newer engine with the more advanced fuel system would run cleaner. ??? I plan to also reuse my coated Hooker 2055 headers and just block off the EGR tubes . . . any issues in that?

Now, if I can remove the smog stuff, I would likely get a March serpentine system just to pretty up the bay and to get one of the newer and smaller A/C compressor units out there. If I can't remove the smog stuff, I would still like to get a smaller A/C compressor since my old monster one is toast anyways. Here's the March system I'm looking at: http://marchperf.com/sporttrack-swp.html

I really don't want any surprises here and the only two wild cars left out there (assuming what I've said so far is based in reality) is picking a good distributor and hoping that the Walbro 190 can push the fuel. (the crate engine may come with a fuel pump).

Any thoughts and advice would be appreciated as I need to get to the parts ordered soon.

Would depend on your local testing rules .
Some areas require all the junk to be in place ( and operational as well ) regardless of what the actual test figures are

Re: Ripping it all out. Will the new engine work?

First off verify if your emissions testing includes a visual check. If all equipment that came on the car is required(operational or not is another story), then you will already be dead in the water without EGR.

If you don't have emissions testing, it is very feasible that the engine will pass a sniffer test with limited/no emissions equipment.

My friend as a very built AMC 360 in his CJ, and it has no emissions equipment at all and passes the sniffer with flying colors.

Re: Ripping it all out. Will the new engine work?

You want to be careful with blocking off the headers air tube. I did that with mine, but the air tubes broke off. It sucks cause it happened at the track, on a pass. Could have been a defect, (plus those airtubes are super thin anyway)It only happened on one side. Really sucked cause it was jet hot coated but it was a easy fix, my buddy welded up the header. We did the other side also, but it really cleaned up the engine bay and so much easier to reinstall. If yours weren't coated I would just weld them up. It will look cleaner/more room to work with also.
