Engine Question??

I have been searching for engines for a littlw while now. I have looked at multiple places and called a couple. I was wondering if anyone has heard of
"Miles Eastside Auto"? I got a quote from them and this is what they said:

99 COBRA 4.6L 4V QUOTED

Year, Make, Model: 99 Ford Mustang
Engine Size: 4.6
TBI, EFI, Carb: EFI
Automatic or Standard Transmission: Standard
2 Wheel Drive or 4 Wheel Drive: 2 Wheel Drive
Overdrive Yes/No: No



The price is $2895.00

Core charge $1050.00

They say that the engine will take 1-4 days to get to wherever. Also they have free shipping on all their units. The price seems too good to be true.
Also, I am pretty sure that this engine would fit straight into my car, just want to verify?? Thanks in advance!!!

Nevermind on that quote....whoever at that place quoted me the wrong price. I just got off the phone with them and they say "$3110 for the engine and then $2,500 for the core charge". So out of my pocket, we are looking at $5,600 for a comlete Cobra engine. I don't know about that!!
