I think you could get a 400 also.

i have had four of them and they were all 318-2 barrel with auto trans, right now i have a numbers matching 1974 road runner with a360-4 barrel and auto trans,


the 1975 roadrunner came wit 3 options: a 318, a 360, and i think either a 440 or a 426 hemi.


I have one too they could of came with a 318 360 400 and 440. also they could of came with a lame 400 2 barrel or a ho 400 with a t-quad. Hemi's were done in the earlyer 70's, along with the 383 and 340


i messed up no 426, instead 400, 383, 318, 360, and 440.

318ci, 360ci, 400ci, 440ci

318-2brl.was standard.optional engines were:360-2brl.,360-4brl.,400-2brl.,& 400-4brl..1975,the last year for a b-body roadrunner,had the biggest choice of engines of any year!-the 360 & 400 4brl.engines were available with the catalytic converter delete option & true duul exhaust!


my dodge red book goes to 1974 with options of318 4 bb,170hp,360 4bb245hp,400 4bb250 hp,440 4bb 275hp..not sure if 75 had 440 but def had the rest.


318 or 360...Check your VIN (Vehicle identification Number)...




1975 roadrunner eng option was 318 2bbl, 360 2bbl, 360 4bbl and a 400 4 bbl. 440 and 426 was not an option. 7300 were produced and half were 318`s. I had one with a 318 4spd trans and everything I find says the only manual trans was a 3 speed. yet mine was a factory 4 spd car.

I had a 73 With a 360 4 Bbl. Automatic, but I purchased used. It had a Banana Torq Conv, Dual Point Ig, Edleblock User the Carb & Header's. The Automatic was more of a 3 speed inline Slam Shifter. Late models 73s I was told came with the 360. Which I cannot find in any Brochure.

I ment to say Edleblock Intake under the Carb on the 73 360 in above answer.
