Thanks for the replies. Jon, I agree on the Lotus 7s. Even with almost 600hp at the flywheel, Locosts and Brunton Stalkers were usually beating us; but it was a battle. There were about a dozen of us who could be in contention for FTD any given day with Lotus 7s, Cobra replicas, and Reynards in the mix. It just depended on the driver....and luck!
I'm going the LS2 240Z route for a couple of reasons. I think it can be relatively inexpensive. It took me the better part of $50K to make my Cobra competitive. Enough money that I didn't really want to risk it on a big track and they wouldn't let us run hill climbs since we had no HALO cage; I wasn't willing to put one in the Cobra. Besides, I didn't build it for big track work in any case. Seems to me I can build a fairly fast LS2 Z for quite a bit less than 50K.
I like the idea of a hard top and a cage without ruining the lines of a car.
Finally, I miss having a Z. Sold my last one in 1992 and I've missed them ever since.
Thanks again folks! I look forward to future "spirited" discussions. Maybe I can even meet a few of you. I know there's at least one Z on the East Coast running SCCA events in the DC area. Several of my Cobra club members run there as well.
Cheers,
John
