Neil, I just perused your build thread. That car seams more like a Can Am car (yea I know its a Manta therefor shaped like a McLaren) than a land speed racer. What with a Porsche transaxle, Chevy V8, what looks like road race suspension, those big meat tires etc. I bet that thing would go like stink on a coarse.
I maybe read there were enough made to get you in a production LSR class, or something like that. I'm sure it will go great in LSR but I am wondering are you going to road race this car? Is there any way it can fit in a vintage road race class or are to many of the components too modern?
