RPM's ?

[86 LeSabre LC]

What rpms does the Hot Air get its peak power and torque at ? Stock carbed & EFI

Then maybe some modified engines. RPM's/HP/Tq

Then what is safe & durable highest RPM range. RPM's/HP/Tq

All with stock crank and rods.

Thanks Steve

Some might disagree with me. But for my daily driver, I leave it in D and let it shift itself ~5,000rpm for most street races. I've accidentally hit the 6,250 revlimiter a couple times with no ill effects but I feel I got lucky that it stayed together. Stock, mine fell on it's face past 4,800rpm which is about normal. With upgrades like the cam, big turbo, ported heads mine pulled very strong to 6,250. Still, I can't take a chance of breaking it again so it's worth it to me to keep the rpms conservative and lose a little hp. I've taken it to 5,500 a few times for the tougher races that there was money on like a Viper GTS even though I would've spanked him bad just keeping it in OD.

Doesnt anyone else have some specs. for me ? I trying to learn more about these engines and what they are capable of without compromising lower end.

BTW thanks Cool 84
