Ok, I won't tell you then about the guy down in South Carolina who has a fast strip Gremlin running a small block BowTie, and is beating the pants off the competition down there! LOL! They hate him...but anyway, I don't see why you can't get over 300 hp out of an inline, it's entirely possible to do so. Some folks think that you have to have a V-shaped engine to get power, and that's not so, a straight six can be really fast with the right mods, just like a v-8 can. Anyway, here's the weights of all the Gremlins that I can find : '70 2-pass. - 2497 ( lb's ) '70 4-pass - 2547 '71 2-pass - 2503 '71 4-pass - 2552 '72 6 / v-8 - 2494 / 2746 '73 6 / v-8 - 2642 / 2867 '74 6 / v-8 - 2855 / 3094 '75 6 / v-8 - 2694 / 2952 '76 6 / v-8 - 2774 / 3023 '77 4 / 6 - 2564 / 2824 '78 4 / 6 - 2556 / 2834 Some of the Custom Gremlins weighed 3 lbs more than a standard in '76-78, so I used the heavier weight. :) As you can see, the earlier the Gremlin, the lighter the car....they used less interior bracing in the doors, etc than later models. Probably swapping the doors out, and removing the A/C will get a late-model Gremlin down to around 2600 lbs to match the early ones, and maybe they used heavier bumpers on the later years, with the hydraulic 5-mph bumpers its highly probable that added extra weight as well. Here's the weight for the '79-80 Spirit sedan, they're lighter as well : '79 Spirit sedan ( Gremlin lookalike ) - 2489 / 2706 ( 4 and 6, no v-8 offered for sedan) '80 Spirit sedan - 2512 / 2714 ( same as above ) So, you could make a light-weight racer out of the later model Spirit Sedan, don't think anyone has done that, the hatchback was preferred for aero purposes by then, though. It'd be different. And I see more Gremlins in junkyards than Spirit sedans, I don't know what happened to all the Spirits ( probably the low production numbers ), there's one in a local ( 2-hour drive ) junkyard, that's beige ( shudder ) and on my website pics, and is only missing a front wheel hub. it's in nice shape, I might have to go back to check it out again sometime, see what year it is. Well, that's all for me, just thought I'd pass on some info. I have paint chip books now, too, so if anyone wants a breakdown of their paint code, what it's called, etc, I'll be happy to look it up for you. AMC ya!
