My garage is nearly finished and then Im ready to start on my 70 cuda. I really like what Ford has done with their mustang line and have seriously considered a new gt500... but the more I think about it the more I want to fix up my cuda. It has me wondering if I can get my cuda to levels of the gt500 at least in terms of power and somewhat in terms of efficiency. It is my understanding that the gt500 runs around mid 11s stock so Im thinking a gen 3 hemi supercharged may be the ticket but Im open to wedge engines as well. An overdrive transmission is a must for me as I like for my rides to be highway ready. As for the efficiency part, my 09 challenger r/t averages 17-18 mpg around town and 22 hwy.... Id love numbers comparable to that in my cuda. Just throwing this out there and seeing what everyones ideas and opinions are. Thanks.
