It’s an early magnesium case, It is not a 7R, but this motor will not put out the power of a 2.7 or bigger motor and I’ve read where this case should handle up to 280 hp or more. It has the squirters and all the windage mods, big oil pump. It is very high compression (12.75:1 JE pistons) using GE-60 cams. It seems to just screem, but I’ve only just got it in and running, not much play time, and fine tuning. It Idles well, and doesn’t seem to want to foul the plugs (I’m using 114 octane gas). Time will tell if the case is strong enough…
