Does anyone have a picture of a Duramax and Allison together from the side so I can compare heights of the pans?
I just took a look under mine, the tranny pan is actually lower than the oil pan. Granted, I have the oversized pan on mine but I bet even the stocker is still as low as the oil pan. Dunno how you could dry sump the tranny?
Thanks for bringing up the Impala again. I forgot about that one. I had seen it before but had not really looked closely at the pics. It looks to me that if the turbo and air intake had been relocated it might have actually fit under the stock hood of the Impala. Either way it looks like the oilpan fit with some notching of the crossmember. So it seems it might actually be easier to fit in their than I first thought. Any body know how close a sbc comes to the hood of one of those Impalas? Just so I can compare to the Camaro.
I there would be room over the fender well or in front of the engine to put the turbo. That appears to be the big obstacle on the Impala. I would like to keep the hood down to about a 2in cowl if possible.
They put a Duramax and Allison into a 1989 1500 4x4 and ended with a curb weight of 4700lbs. Sounds to me like the Durmax isnt as heavy as I first thought.
After looking at pictures of them on Banks website The block does not look all that different from the LS engines. Although it is probably a little beefier and i am sure the heads are heavier than ls heads, I think it maybe close in weight to a big block chevy with iron heads, which isnt that great but isnt that bad at the same time.
i have a 66 impala SS, took out the 327 about 7 years ago so i cant help you on the sbc question.. but it isnt that tall i have a std deck BBC in mine and can fit a 4 inch aircleaner with a drop base, but only with a torquer2 intake... running a dualplane and there is only room for an oem aircleaner or some open element edelbrock crap... so id say it isnt much taller than a 1.gen..

but looking at the picture on your last link the tranny looks BIG.... you would propably need to either remote locate the tranny filter and raise the tranny oilpan (perhaps an electric scavenge pump and a gravity feed oil reservoir to the pickup in the tranny pan will buy you some inches) or mount the whole engine/tranny horizontally and have a BIG transmission hump/tunnel

Right now I am thinking just leave the pans as they are and make it fit. But I dont want to run a huge cowl hood either. Like I said only about 2in hopefully.
Probably going to take up some interior space but I guess we will have to see.
