CJ 7 Swamp Buggy rebuild/ mods.

I have not made any posts in a while. So here we go. The last time I posted I mentioned that I rebuilt the TF 727 Transmission . and put a snorkel/ breather tube on it to water proof the air intake. I have recently added a new motor to my jeep buggy. I put a AMC 258 i6 / 4.2l back in my 86 CJ7 but this motor has had a little work... It was bored out 60 over with a mild cam. It has the 4.0 head and an aftermarket header also. It took a little modifications to get all the belts and pulleys to work but what a difference. It has a Holley 2 barrel carb and an HEI distributer. I also replaced the stock gear box with an HD replacement gear box and pump. I also removed the stock fan and replaced it with an electric pusher fan on the front between the radiator and grill. Had to cut the vertical bars on grill but a sacrifice worth making. This allows me to run up to 4'-0" of water by shutting down the fan. I also just changed out the gears on the Dana 300 . I went with the LoMax 4 to 1 gear kit. What a difference! I haven't changed the gears in the axles and I am running 40" tractor tires. This beast pulls now. I know I've increased the horsepower greatly but don't know how much... It has to be 40-50 hp. Anyways, that's all for now. Pic is before motor swap.
