  • 8-71 small block to big block compatibility.

    Hello all. I have a question about the 8-71. I have a decently built small block I want more out of, but I'm unsure if the next engine will be a small or big block. Usage will be off-road play only, no racing, but mostly hard use with lots of throttle. Question is, besides the intake, is there any other difference between the small block and big block kit? When the current engine blows, I'd like to still have the option to put it on a big block if I decide to go that way. Thanks.
