lg4 or lb9
I have an 84 z28. I know it has the lg4 305. I just picked up another 305 and I am trying to figure out if its a lb9 or the lg4. Is their anyway to tell the difference. I the engine I picked up runs I only needed the tpi setup for my 87 iroc. If anyone know a way to find out the difference between the lg4 and lb9 let me know. Thanks
