Just my opinion. It makes no difference to me either way. I've literally been through every stage of the Chevy engine evolution on the old Gen I platform (I'm an old fart), beginning with the original 265 V-8 in my first car, a '55 Chevy 2-door hardtop. I've been through carbs to multiple carbs to propane to throttle bodies and TPI, and I resisted going to the LS-series engines for a LONG, long time. I wouldn't switch back now even if you gave me a brand new SBC crate motor for free.
On a side note, I know some folks have heartburn over computers (ECU, PCM, ECM, ECU, whatever). I say 'get over it'. Literally MILLIONS of cars and trucks, including all modern four wheel drive vehicles, have them and they work flawlessly every day. The one thing my Gen I SBC could
NEVER do is tell me why it decided to wake up one morning and run crappy for no apparent reason. My LM7
can tell me why, and everything else that's going on
right now when I plug in a scan tool.
FWIW, my son just picked up a complete LM7, w/PCM for $700.
Like I said, it's just my 2 cents worth. Ultimately, everyone needs to be content with their decisions. After all, this is supposed to be fun
