66rmack Posted October 2, 2015 Share Posted October 2, 2015 Anyone know what kind of hp and tq they make? My dad says the 673c "250" had a lot more power then the 711 turbo. From a cubic in side I find it had to believe. Cause the 711 should make a considerably more tq giving the cube differences. Anybody have any power numbers? 1 Quote Link to comment Share on other sites More sharing options...
AZB755V8 Posted October 2, 2015 Share Posted October 2, 2015 Can't say I have heard of a factory 711 Turbo?? All those old turbos made only a few pounds of boost but good for a lot of smoke. They where just plain big as well.The 250 or even a 237 probably does have more power than any 711 did turbo or not. Quote Link to comment Share on other sites More sharing options...
