There are a lot of other things to factor in on this deal
I didn't mention, nor are they in the pics
1) Does it include the oil pan w/ pickup, dipstick & tube ( if so, which one?, will it fit your car?)
2) Does it include the valve covers and coil pack set w/ wires?
3) you mentioned the guy said he has a "conversion harness", this is a very broad statement ie. is it a stock truck harness (that came on the LY6) that has been modified for a stand alone setup, or is it a aftermarket purpose / specific built harness?
Which pcm? you have a gen 4 block & timing cover/ cam sprocket, but a gen 3 crank (24X wheel) You may need both a knock sensor/s extension harness and a cam sensor extension harness ?? (gen 3 to 4)
the truck harnesses "exit" the engine off the front drivers side, where as the "LS" car and aftermarket are the "cleaner" looking/ routing exiting the back of the intake
4) is the DBW throttle body included as pictured, is that what you planned on using, or a DBC style need the pedal / harness assembly if going DBW
5) Are there any of the front drive accessories with it? (ie balancer, alternator, p/s pump, water pump, tensioner/ idler pulleys, etc)
If so, which ones? truck (LY6), F-Body or Y-Body
6)Also, who spec'd that cam and what were the specifics/ application for it? You said that he built it to "spray it" ?
that cam is geared more for mid to topend
How do you plan on using this engine? A DD, street car w/ some track days, or track car??
Auto or manual trans? (auto is going to require a stall convertor)
There may be some power "left on the table" also, due to that cam having approx. 15.5 degrees of overlap, which much higher than desirable using the LS3 heads, usually like to see 4-7 degrees of overlap (I may be a bit off on the math with the +2 degrees ground in)
It makes it more difficult to tune
Did he tell you if the heads were milled at all? ( given that the pushrods are .050" oversize (stock is 7.400")and still using the stock MLS head gaskets (.053")
And the question that I haven't seen asked yet, is:
Why is it for sale, if only 8k miles on it?
Hope this helps
Jeff
