I recently put a 5.3 in my 66 and it was pretty easy. As long as you are not scared of a little wiring. If you really want to make it easy go to www.brotherstrucks.com and order the 63-72 GEN III motor mount kit. All you have to do is bolt them up to your small block frame and crossmember holes and drill 1 bolt hole on each side of the crossmember. This kit runs around $250.00 but is worth every cent because it takes out all of the the guess work. Another issue you will have to deal with is fabricating a gas tank and getting it in the rear frame rails. Do yoursef a favor and have the tank fabricated to use the stock GM fuel pump. It will save you a ton of money over a high psi aftermarket one and be a better quality too. You will also want to find a 98 or up LS1 camaro or firebird radiator and electric fan setup it fits perfectly. There are many sources out there that can modify a factory wiring harness or make you a new one for $250-$500 bucks. You will also have to send the PCM out to turn off the anti -theft ( it wont run if you dont do this) and do any custom programming you might want. This is another $150-300 depending on who does it. If you go LS1 you should expect to spend $4-6k and have a higher mile drive train. That is why I went with the vortec I found an L33 option all aluminum 5.3 310HP 335 FPTQ with 12k and a 4L60E with 2K (the tranny on the motor was a 4x4 version and had the wrong output shaft.), all of the wiring harness, fuel pump, and pcm for $2,500 bucks. I had around $4,000 in the project but I offset it when I sold my 350/350 for $1500. Go for it man you can do it!!!

I'm going to disagree with a few of the thoughts above, especially the radiator. It's not as 'perfect' as a fit as it could be, and the stock '67-'72 radiator is more than sufficient. The F-body fan shroud and fans are worth getting if they're cheap, though. It's not hard to make some very simple brackets that hold it up perfectly.

I've done two. One in a 69 1/2 ton and one in a 67 3/4 ton. First one is a LS1, second a 5.3 with a 1992 five speed truck trans behind it.
I use a carter P5000 fuel pump and get a sending unit for the stock tank from a 71 or 72 that has the return line in it, and run the return line through the bottom of the cab beside the original suction line. I get a cable actuated throttle linkage from the same year trucks, mount it and drill a hole for the cable. I fab the 1/4inch steel adapter plates myself and use your factory 68 engine mounts. Any chevy bolt pattern trans will bolt up. You will need a special flywheel and pilot bushing if you want to run an old style 3,4,5 speed trans. I use the stock rad. With the 5.3 out of a truck, that fan works great. With the LS1 i used the stock fans. I use the stock harness and modify it myself, and I use HPTuners to program out the VATS and modify any other parameters. I use an adapter to connect the new style power steering pump to the old style hoses. Well worth the swap in the end.

The 66 model has a much shorter front end than the 67-72 and doesnt allow clearence for the stock radiator when using the early classic motor mount kit. Furthermore the camaro radiator is aluminum with a dual fan setup that will provide much more efficiant cooling . The camaro radiator and electric fan setup is cheaper than buying a good set of fans for the stock radiator if you shop around for a good used setup. Little things like this can be the difference between spending 4k and 8k. It can also be the difference in getting it done in 3 weeks or a year. You will hundred dollar yourself to death if you dont find creative ways to stay on budget.

Yeah, but he's putting it in a '68 C10 - the factory radiator works fine for the LS1, and unless the old one was totally trashed, he's probably got one. The Camaro fan shroud / fans works fine on the '67-'72 radiator.
