At least he'* doing this the right way....
He has an HD trans already, now he'* taking a higher compression block and */Cing it.
That'* the way to go, vs everyone with a regular trans and a N/A motor....I'll possibly be in that boat this winter....
As for the boost levels, I can't imagine that with the stock pulley, that you'd be running any higher boost than maybe what a 2.5 pulley would put into the L67 motor....Possibly even less boost than that...

So far, this is what is going to find its way into the L27 (aside from the normal L67 components), and all of these are new: lifters, oil pump, knock sensor, gaskets, plugs, wires, water pump, fuel filter. Fuel pump will be fully tested when the engine is in running shape, and that will be replaced if pressure is even slightly below spec. All of this will help ensure this motor will survive in its new environment...hopefully

The compression ratios are still different. The N/A'd motor has a higher compression ratio than the */C'd does.....Higher compression with the addition of an */C equals out to higher boost than what an L67 would have with the same */C and pulley?

Sandrock are you going to contact Gm tuners to make the adjustments to the PCM?

I would only need to make PCM adjustments if I want more fuel, timing, etc. As far as the computer is concerned, it will still see an L67...all the sensors are the same, cubic inches are the same. And remember, I am not looking for performance out of this...just a good running substitute.

Ok, now for all of y'all interested in how all this is shaping up...
Here is what we started with...93 L27 with about 92k on the ticker...sure looks grimey!
Now let'* pop off the top and see what'* inside....
Hmmm....very VERY clean in there...
Nearly bare...
Don and I scratching our heads on something...
Freshly painted manifold with new sensors.
Take a look at the carnage all over the pad...
Supercharger goin on....
Now with damn near everything needed
Next steps are to put on coated front exhaust manifold, new oil pan, L67 balancer, a/c bracket, and...??
