What If Build Ideas...for Land Speed Racing

Don't shoot the messenger.......BUT.......I wonder how much more affordable an LS platform of some such would be?
Likely much more affordable overall, but then if I build the turbo LS for my Charger, as an example, I can save money on good brakes then too as I would need to continue driving and run into the side of the mountain at the end too. Actually, do it all on a CC and never even have to pay the bill! All joking aside, it would likely be the least expensive way, just not an option in my thoughts there. Thank you.
