Undy Dave a agree with you on the rpm and stroker limit. We both think alike. The Lemans rods are heavier than the scat rods I got from Barry R. The eagle rods in my 452 motor where lighter. Again staying with the 6,000 rpm limit had no bottom end problems after 8 years of autocross and road racing. With e-bay and swap meets all over the US, it's easy to find Jag rearends, ( center assembly for 2-300.00 dollars. ) Get a couple of different ratios, like 3.31 and 3.07. IMO the 2.88 ratio is weakest gearset and would limit them to 450HP and torque. The others IMO are stronger. With the range of 5 and 6 speed trans now and the T-56 holding 850HP and torque, you can have your cake and eat it too. As far as the high reving 427's they need to make up for the no torque bottom ends. Are they faster at top end, yes but who will holdup longer?? The GT-40 lemans cars had limiter for 6,500 rpm. This is how they survived the 24 hours. It all comes down to the right parts for the right application. This is the nice thing about this forum we learn new things every day on maken our FE motors run better and with more power.
Dave there are guys running over 7,500 rpms with a single carb, the carbs are either 950 or 1100 cfms and these are stroker 482 motors that are still pulling like freighttrains. Morris is one. Dave S, is another one but with a olberg setup, this is a different deal.
It's OK Dave, we will keep fighting cityhall.
