318 la / mag

block cast says it’s 91 318 motor . Which is first year for magnum . But yeah someone put this motor together as block was zero . But all guts of block are magnum - roller cam and lifter , the spider thing

Well that is interesting Because everything is pointing to it being a '91 318 TBI roller cam engine with the factory 302 closed chambered heads and factory mopar rocker rails.

If this is true, then it is a flat topped piston with factory 9.2:1 cr and full floating connecting rods.

Just like this '91 318 TBI roller engine that I converted to Edelbrock 4bbl carb.


Factory pistons .040 ths in the hole, no valve reliefs.
