anyone ever have a Dodge Rampage??

They are neat cars. The guy down the street had a Scamp, just the plain version. I'm not sure where it went, it's been replaced with a p.o.s. Honda that never runs.
I agree though, you should look for a D50 if you want something light to dump a 318 in, it will be much easier. Every now and then a chassied 2.2 car pops up for sale.
