A while back I was asking for advice on fitting a small block V8 into my 1966 AP6 Australian Valiant, but after looking into all the hassles with needing to get the car certified (New Zealand), I can't be bothered with it.
Bit if I repower with a slant 6, everything would be hassle free.
I have the original slant engine for the car that could be rebuilt, but I have the opportunity to purchase a 225 two barrel slant motor out of a 1986 Dodge Ram.
I have some questions about the 1986 motor.
Will the 1986 motor perform as well as the original 1 barrel 225 which was rated at 145 horsepower?
I've become aware of the HP and torque ratings switching from gross to net some time in the 1970s, but I can't quite get to grips with all that, maybe the later engine may be more powerful than the original?
All I know is I don't want less power.
The 1986 motor had a 3 speed manual gearbox on it, so will it bolt up to my original 1966 904 Torqueflite?
From what I've learned so far, the later slants, post 1967, have a larger diameter crankshaft end, so it wont fit the earlier torque converter, however I think Hemi Performance in Australia sell a reducer ring for this conversion without having to get another torque converter?
Can I easily use the original 1 barrel carbs accelerator cable on the later 2 barrel?
And is the 2 barrel setup to work only with the lean burn ignition, and when I use my original points ignitions, (as I'm planning to do) will the 2 barrel be suitable, or should I put the old 1 barrel and manifold on, or maybe look for a pre-lean burn Carter 2 barrel?
I think that about covers what I need to know. Any advice would be appreciated. Thanks.
By the way, my car has a firewall mounted kickdown mechanism, maybe that simplifies the accelerator cable situation?
