i did not realize they had the 750 out . i kinda think the version with the plastic center is kinda interesting for heat reasons , like the thermoquads . they look a little "george jetson" to me in pics , have not seen 'em in person . pics of the 600 black diamond versions , which is just a holley 1850 basically , is real nice lookin to me for some reason .
Yeah the new aerospace resin sounds promising, theve put them throw many heat cycles so doubt their would be a frepeat issue I've never had nor seen a Thermoquad in person, and thats prob due to heat cycles of the oringinal resin crackin over time
