Hi guys, I am starting to rebuild my 57 and I need to figure out what to put as a powerplant. One of options is to rebuild 350 that is inside, the other is spanking new LS3 ... but I have 572 Dart with 8-71 that was used for a seasson for racing. Now it is just waiting in my garage.
The problem is that I want to use my 57 quite often in the summer months. I want to be able to drive it in traffic, not overheat, have a "decent" MPG - not like 1 MPG ( I used around 12-15 liters of fuel per race of 98 EU octane gas - that is 95 in your standards ).
So I want to get a decent ( in reasonable leve ) MPG, not overheating.
This thing is crazy loud - that is also an issue for street. Being able to talk is a good thing
I don't want to cut the hood, so the blower must go. It might be replaced with a prochager that will fit under the hood or I will just go NA.
Going NA will force me to make some changes.
I'm trying to figure out is it possibile in a reasonable fashion.
I have to go down with power also - don't need that much on the street. Right now its over 1000hp and 850 ft lbs on crank. And I want to use a tranny with OD so no Powerglide or anything like that.
What do you guys suggest ?
