Phido Member 58 Member For: 21y 3m 20d Posted 04/07/05 07:27 AM Share Posted 04/07/05 07:27 AM For the same money I would..-Buy two BA I6 heads.. -Go get a alloy block casted of a V12 60 degrees, using falcon bore spacing, bore, stroke, etc etc etc-Machine said block-Equipe with strong pistons and rods and custom crank-Tune and map with aftermarket ECU-Cams, porting, valves and springs for the I6 heads Say hello to your 8.0L QOHC QVCT 48 Valve V12 pushing over 400 naturally asperated Kws to your rears.. Place this engine in a Fairmont Ghia body with a 6 speed and suitable brakes/clutch/shafts. Okay, it would cost maybe $50,000... But then again I would imagine that engine wouldn't be cheap either.. Say $100,000 all up.. Nice little package. Link to comment Share on other sites More sharing options...

They are certainly great bang for bucks motors. Ford have Ford motorsport crate motors too - I think you can get a 600hp version of the Boss motor somewhere.I would say the 20,000 price would be about the max - they are probably much cheaper than that.

cobrav8 Member 1,969 Member For: 19y 10m 25d Gender: Male Location: New Zealand Posted 04/07/05 10:32 PM Author Share Posted 04/07/05 10:32 PM Cobra weighs just over 1000kgs, and yes, the Falcon is a bit overweight.It would be interesting to see how much weight can be saved with kevlar panels etc (like BMW do by the way on the limited edition M3).Granted - injection is a better way to go - more power, and more efficiency at the same time, but..... more complicated, it is nice to work on a car that you can do everything yourself. Also - for the amateur guys - the carb is much cheaper.My car is kind of a mix between the two - it has Hillborn injection - huge big butterflys per cylinder - enormous power - but drinks petrol like mad, runs too rich at low throttle positions.Anyway - none of ius would put one of these in a Falcon - just thought you might like a look on the other side of the fence.Here is a pic of my fuel injection system: Link to comment Share on other sites More sharing options...
