What Year was the engine first commercially available.
Very important data.
What year's technology was this engine built with, was it built with technology that won't be in common use for years? (E.G R35 GTR) or was it built with old technology for its age, like a 2002 Windsor V8.
Semi-important data.
Who built the engine.
Very important data.
What is this engines name/model number or if that's not possible the car and model the engine was installed in.
Very important data.
Is the engine an inline (I3, I4, I5, I6) or a V engine (V4, V6, V8, V10, V12, V16) or something else (VR, W, wankel or flat)
We only want I4, I6 and V8 at the monent!
Very important data.
What kind of valve setup does it have. - Pushrod (OHV) - Single Cam pressing directly down on buckets? (Direct SOHC), Single Cam with Rockers (SOHC), or (DOHC) Does it have Variable Valve Lift (VVL), Variable Valve timing (VVT), or both?
Important data.
2/3/4 or 5 valves per cylinder.
Important data.
How many barrels and how many carbs. Single Twin barrel carb? Dual Sidedraught Webers? Dual 4 Barrels?
If its got some kind of strange carby, what is it?
If it is Mechanical Injection (e.g Kuglefisher), EFI, Single point, Multi Point or Direct? How many throttles?
Important data.
Full air intake system/airbox, exposed filter or just some bare trumpets?
Secondary data.
The bore of each cylinder in mm.

Very important data.
The stroke of each cylinder in mm.

Very important data.
Capacity in Litres (bore and stroke tell us this too, but this helps confirm everything is correct.

Very important data.
The engine's compression ratio.

Very important data.
How highly tuned would be carburettors/distributor or engine computer be? Is it likely to be conservatively tuned for low emissions, low octane fuel and good fuel consumption? Or would it be highly tuned for power?
Secondary data.
How wild would the camshaft design be? is it likely to have a very mild cam designed for smooth idle, mid range torque and economy, or a wilder, rough idling cam for top end power?
Secondary data.
Which of our manifolds would this engine have? Log, Short Cast, Tubular Headers, Long Tubular Headers (4-1 style), Race Headers (bundle of snakes).
Secondary data.
How many mufflers, do they look like restrictive designs like reverse flow, or do they look like good straight through sports mufflers? Secondary dataCatalytic Converters? EGR? Air Pump? Some other horrible emissions gear we've never heard of?
Semi-important data
Anything else we need to know about it? any assorted facts and stats that may be useful go here :)How much power did it make? Please convert to KW from HP. - If its an old car (1970s or older) please note if its Gross or Net - (see http://ateupwithmotor.com/automotive-terms/47-gross-versus-net-horsepower.html).

Very important data.
What RPM does Peak power arrive? - Also, any engines you can find a dyno graph for would be amazingly helpful!

Very important data.
Peak torque in NM? (If you can't find it in NM, CONVERT IT!)

Very important data.


What RPM does Peak Torque arrive?

Does it remain relatively flat, or is it all peaky?

Very important data.
