Well to get back to topic for a bit..... I would pay 1000-1200 for a 836 punched motor with some head work done and a mild cam. you know, work like what the headmaster does.
Hey Eldy, in reality, an 836cc top end for your K8 engine will cost you that, and more. The following prices are "guesstimates", but not far off the mark:
Wiseco 836cc kit $400.00
Cylinder Boring $200.00
Megacycle cam $300.00
Mild head work by Mike $400.00 (plus)
Heavy duty stud kit $100.00
New H/D cam chain $50.00
Top end gasket set $100.00 (the Wiseco kit comes with a head gasket, but you still need a base gasket, O rings, seals, etc)
There's $1550.00 without trying too hard, (you doing the work, with no M3 cam chain tensioners, new rockers as recommended by Megacycle, Dyna ignition etc) so the dream of a cheaper "performance" engine, is just that, a dream. You might be lucky enough to find some good used parts on Ebay for a bit less, or get real lucky like Sean and I did when we bought that complete worked 900cc engine with an oil cooler and ARD magneto for $400.00 complete, but these kinda bargains are few and far between. That's why Tom would be a lot better off with a Krome Exchange service, IMHO. Cheers, Terry.
