Aluminum makes a difference if you’re serious about performance. I switched to aluminum rockers on my racing engine and saw better responsiveness at high RPMs. The heat dissipation keeps everything cooler under sustained load.
Thanks for all the comments everyone. You’re right about the maintenance costs – I’ve been researching and it seems like finding a good independent Jaguar specialist is crucial. The no-reserve aspect is making me nervous though. Anyone know what these typically sell for in good condition?
I’m leaning toward bidding but being strategic about it. I think with the no-reserve format, there’s going to be aggressive bidding from collectors. I’m setting my maximum and sticking to it no matter what.
