I know about all there is to know about 425's but I admit, I've never had an Olds 350 before. Now I do. Gold engine, black air cleaner 2 barrel.
Did they waste their time making different compressions versions of these
engines? I mean I can see the having a 310hp 9.0:1 2 barrel 425 and the hairier 375 hp 10.5:1 4 barrel version but were they still playing with cams, different heads and compression in 71 as things were winding down? I know they plopped a four barrel on some. I'm staring to scour around for some go fast(er) parts for my Cutlass. My 425 is an animal and I have to restrain myself from dropping it in the Cutlass.

 

In 71 2 different 350's (L65) 2 bl 240 gross hp or 160 sae net and 4bl (L74) 260 gross and 180 net both have 8.5 to 1 comp.
