Here’s a 1970 Super Sport Chevelle with a 396 / 375 cloaked in “Shadow Gray” GM factory paint. I was so doe-eyed over “ OMG!! Is this a REAL L-78?!?!?” that I forgot if it’s an automatic or a 4-speed!! Nor did I look at the carburetor. Obviously there’s an aftermarket manifold and someone else was using their cellphone flashlight looking at casting numbers on the engine block to verify yea or nay. For the sake of this summer weekend, let’s pretend it’s a valid 396/375 L-78 with a Muncie M-22 Rockcrusher. :-) Have a great weekend everyone!!!
