Rich, Devil's advocate here (no insult intended, just an opposing view)... "After following this thread for awhile I think many of you guys are going to hate my plans for the new Mexico Crusher 72 Javelin. <snip> The first time I take one of my cars to an AMC show and I am told it is not good enough or stock enough, will probably be the last time I will attend one of these shows.!" If that becomes the attitude of the owners of such cars, then allowing them at all might be wasted effort, since they won't be back the next year. ;) But seriously, I'd actually be glad to see your car at a cruise-in or local drag strip. But in judged competition with other AMCs still powered by AMC, I'd be very offended to see them judged on an equal basis. Separate class, maybe....or a hefty automatic Points penalty within the same classes, maybe. But as equals? No, because they are not. "I feel that I have saved this car from certian destruction, and if I want to upgrade it so I can drive it to more shows, I will." Some wouldn't classify such a swap as an 'upgrade'. Hence, the need for separation. "If the car was a rare model or something more valuable, I would not take this route. That is why I sold my Donohue and did not Prostreet it. What is the difference between me using a Chrysler motor and Chrysler trans since it already had a Chrysler trans anyway? It is not much different then putting a 401 in a Nash. Richard Payne" Yes, techinically, it's not very different. But the resistance is borne of the attitude that if it's got an AMC engine, it's crap. SOOOOOO many Big Three fans believe their own B.S., and it has spread to become near-gospel in the hobby (tho rarely is it said at a drag strip when the Rambler is alongside, seconds away from stomping the Chebby's guts out). When you're kicked long and hard enough by the same ignorant masses, you decide not to deal with them anymore, and to surround yourself with like-minded people. Hence, the gate is slammed on non-AMC powered cars. Do to your car what you will if you like, as it's yours. But to expect those that keep them AMC-powered to treat them as equals is unreasonable. It takes tenacity to keep it all AMC. Using other engines is a form of surrender in the minds of the faithful. Just as a qualification, tho- I dislike all inter-marque engine mixing. I think 350-powered T-buckets are plain stupid, as Ford makes a perfectly good V8 of it's own. I also don't care for it when the factory does it (so I don't particularly like 2.0L or 2.5L Spirits and Gremlins. I don't want a 2.8L Cherokee to be seen in my driveway, either. But then I'm a bit extreme in that feeling. Still, I've seen a 426 HEMI Gremlin and wished it was mine. I'd have preferred it was a 401, tho...but the extreme nature of that build was the draw for me. John
