I'm considering going chevy small block [img]/wwwthreads_images/icons/tongue.gif[/img] in the YJ this summer. The 6 is really marginal with the added weight my Jeep has put on over the past few years. (tire carrier, winch, hardtop, rear jamboree rack coming up) I could go AMC 304 or 360 also, and mount it easily to the 999 auto in my YJ (as I understand it), but I've heard the AMC v-8s with the distributor hanging off the front of the motor ain't so great, and honestly I don't know that much about them. (I know plenty of you will tell me they are great motors [img]/wwwthreads_images/icons/smile.gif[/img])
I'm fairly familiar with the chevy smallblock from my old chevy impala days, rebuilding and playing with a bunch of 283s, 327s, 350s, etc.
Do you guys think that a small block chevy, in good shape, carbbed with a quadrajet for good off-road ability, using a GM HEI perhaps, with a dual exhaust, and twin generic catalytic converters (one in each exhaust) but no other emission parts, would pass a dyno emissions test?
I don't have a visual here in Massachusetts, but they just instituted the dyno a year ago, and I would need to pass. I'd prefer to stay away from injected motors, as I don't know much about those either, and really prefer the simplicity of a carburetor and a basic fuel pump.
I know it's kinda a general question, just looking for opinions. [img]/wwwthreads_images/icons/crazy.gif[/img] My 999 and 231 are kinda old too, at 200,000+ miles, but still run great, so a motor/tranny swap would be considered too. What's the best way to go?
