70 dart 470 ci drag car build.

That’s kind of a hard question unless we know what direction you are heading. The transmission blankets have gotten much better and thinner over the years but the shields take quite a bit of room. Im

Yes 727, whatever I need in case it runs in the 9s
I guess I also need to know if the blanket and shield serve the same purpose is a blanket a better option because of possibly holding in fluid in case of total destruction.
