Motor took us 15 minutes to slide in, and another 20 to get fully bolted back in. No mods needed, but we had to to have someone one (me) under the car to push up on the transmission so that we could get it to slide over the crossmember and into the tunnel. Fun.
To be honest, the swap is pretty straight forward. Not ahrd per se, just a lot of things to get done. Day one (8 hours) a lot of joking around and the mayonaise filled KA came out. Next day, (about 6 hours) we got the CA cleaned up, emissions/vac lines removed, a/c removed, p/s hooked up, bolted up, and most of the stuff on it. Day 3 (8 hours) fixing harness, mounting IC, fuel, spark, and cranking it. Really, not a hard thing to do.
Now getting it to run RIGHT is the challenge...
BTW, got the motor from
http://www.jhotexports.com $1282 shipped to my door, but forgot the hoist, so me and 4 close friends had to get it out of the delivery truck. Not fun.
