I think Hal is right regarding diesel as being the best for milage, reliability and durability.

While Ive have wanted a diesel to play with do some time dont know I want one in the GMC. How is the noise factor with that?

Of course, it would sound better with a little turbo whistle, kinda like the duece and a halfs in the army. [mechanic told me they put the turbos on those to lesson the blck smoke emissions and they didnt really make any more power with them. Hmmmm....]

MikeS, as discussed on FB: The HT383 should work fine, may even fit under the stock hatch depending on the manifold you go with. I had a vega with the mid engine, twin turbo 350/425. BIL has it now and will be reomving the engine to put in my Monza and a built 700R4, but we need to change oil pans. I can send you some pics to give you an idea what to use. I THINK it would clear a 3.75 stroke but not sure

He is contemplating a big block for the car, if he goes that route the pan will be for sale.

The issue with the WP block and longer skirts could be a problem- It looked like the deeper skirts on the LS was going to be as well, but the double tilt idea might get around it

THE LS hybrid is a great concept for HP use, but I dont think it really offers much for our application at the lower RPMs we need. I think the low end airflow on hte Vortech type heads on the HT383 would be as good or better
