Got my new Peterson's in the mail yesterday, there is an article about a company called "turnkey" that sells complete Gen III chevy blocks, 4.7, 5.3, 5.7, and 6.0. I guess they have "partnered up" with Advance Adapters to make these available. Article shows part 1 of the install into an 83 or so Blazer. Ive got the 5.3 in my Tahoe and love it. Apparantly, the engine and kit for the 6.0 runs around $5600 versus a RamJet 350 around $4800 to $5000. Can anyone think of a good reason why I shouldnt consider doing that swap into my 89? Oh yeah, new blocks will mate to most if not all older trannys. Food for thought /forums/images/graemlins/dunno.gif

The factory fuel injection, ignition system, and engine management on the Gen III engines is a nice setup. The modern technology has a lot of advantages. If you are afraid of CSK (I definitely wouldn't be) all you have to do is swap out the pistons to eliminate it. Good time to swap in a hotter cam and go fast.

I'd like to have one of those 5.7's out of the new GTO. I believe it is a Gen. III motor.

I believe the 6.0 is 364 cubes. Stock it will put out around 350 horses and about 390 ft/lbs. I'm leaning toward doing a lq9/4l65e swap into my blazer. There are better deals than turnkey though.

Might as well go LS1 if you're thinking about dropping $5600.

Im going with a 6.0, will put out around 400HP with no emmisions crap on it. It will have the same output as an LS1 but with much more bottom end torque.
6.0's are great, but there in the Garage sits an 8.1 fat block for mine. Injection and all! just got to wait for Howell's new harness and controller. That and some $$$$.

Too bad that 8.1 doesn't have a whole lot of aftermarket support yet. That is one torque pig.
Aftermarket support may not be there yet, but its building. I just found a site yesterday at www.raylarengine.com They got the first aftermarket aluminum heads for the 8.1 and are working on new intakes too. Also Arizona Speed and Marine have a wicked looking 8.1 intake for marine applications that would pump up the tourque.
But then again, 340hp and 455 ft/lbs of torque is plenty for my little 75! If the Howell harness is going to be a while I've had some discussion with people I know back at GM and it is possible to use the 8.1 Marine Controller with the stock harness. all it takes is money!!!!!!!!!
