You say that on inspection it had standard cams... but early you said you have dtiched the HKS cams. Doesn't sound suss at all champ.
Also you say that he said it was going to be sold with, but the ad says differently...

ENGINE
Forged pistons
HKS Cams - You said you removed those...
Complete re-built head w/copper head gasket
Motor balanced, blueprinted and crank tested
Baffled sump
Upom inspecting the block before the sale we see that the following are stock standard.
Standard Rods - Mentions nothing about rods the in the ad, (you know the difference between pistons and conrods right, just checking...)
Standard Rod Nuts and Studs - Mentions nothing about this either
Standard Main Studs - Or this...
Standard Head Studs... or this.........
Standard Cams - Once again think we addressed this....
I dunno man, sucks if it is this way it happened, but what you are saying isn't exactly lining up with whats on the ad.
Also becareful about what you say online, no matter what the outcome, identifying people and then calling people a liar (or as you spell it, lier), is slander and saying you will "f**k them up" is a threat, just saying, wouldn't want to get in shit for that sort of thing.
