What cubic inches are available?
318, 340 and the 400...I do not believe the 440 was still available...
In 1973 the Available engines were as follows. Engines: 318 V8 170 bhp. (SAE Net) 340 V8 240 bhp. (SAE Net) 400 V8 255 bhp. (SAE Net) 440 V8 280 bhp. (SAE Net) 440+6 V8 330 bhp.(SAE Net)
there was no 440 6 bl. But there was an optional 440. U had to get get the GTX option on the road runner!
Simon is right. No six-packs were available after 71.
In 1973 best motor was 340 also available was 318 360 400 440+6 only in roadrunner/GTX440+6
I have a motor with casting number 10200413 it's a 1968 road runner motor. Only motor I know of is the 383 motor. This is a FE motor no fuel pump or carburetor on the motor. Please help. Thanks, firstname.lastname@example.org
