1969 427 suffix?
I found an short block #512 casting block with the suffix LO. When I check in the lists it should be a 1969 corvette 427 430 hp...Hi Perf.
Can it be an L88?
BUT, when I look above the oilfilter it only has one 1/2 threas output ....and then it is a 2 bolt main? 4 bolt should have two 1/2 holes?
Thanks
