LA heads are all going to be lower compression ratio... larger chambers. Also, the Magnum blocks are .015" shorter which helps compression ratio too.. not sure if the roller blocks are the same.
What are your goals for this engine/car? And dumb question on my part: Is this a 318 or 360 block?[/QUOTEMy goals are to build a small block between 325 and 375 hp.
I have a roller block out of a 1990 Ram 3/4 ton and magnum heads out of a 1993 Dakota.
this will be going into a 1968 barracuda hooked up to a 904 with a 3.55 - 8.75 rear/741 carrier.
should be a sweet cruiser.
So I am trying to work with what I got... But if building this magnum head with a roller block would prove to be unnecessarily difficult I'll just look for a 360 non roller engine to build. Currently the car has a 1972 318 block with 1965 273 heads.
