Too rich for my blood. Probably going to flip this thing once I get it and drive just a little.

In that case, let me give you my wish list. :rofl:

Damn! 350lb trans. I thought my 80e was heavy. Such a cool car though.

The rear diff is built into the trans. That's my guess as to why it weighs so much.

Just throw a whipple and a fuel system at it right away build your own z06 lol

Well that's the problem. The compression is high, pistons are weak and fuel system sucks so bad that after market options aren't readily (cheaply) available.

how high is the compression? the new mustangs have to deal with that and seem to handle it ok, 12:1 compression plus 15-18lbs of boost has been doable

I think 11.5:1, the LT4 is 10.0:1. From what I was told the LT1 pistons (which remain unchanged on the LT2) are pretty weak and fueling is a major issue. The mustang is much easier to keep alive especially since it has direct and traditional injection.

the direct injection is the major issue mostly just the cost to upgrade, the 18+ mustangs leave the direct system alone and just upgrade the port fuel system then stock pistons is the limit

I admittedly don't know much about the LT platform. Speed Inc. just posted a 6th gen making like 870 rwhp with a procharger and an LT4 fuel system so they make it work but I can't say for how long. I remember when I asked why people don't just bolt LT4 blowers on LT1 all the time, that was the answer I got. I'm kind of surprised you don't see more LT based high HP boosted GM cars out there. Must be a reason.
