455 specs.

In my area there is a running 455 for sale. Its listed like this

1969 4bbl. 365 HP 510' torque

These specs dont sound right to me. Are they ? If so what car would they be from ?

HP sounds low and torque sounds high, maybe it was rebuilt to these specs ?

Yup. It was available in all the big cars and was standard equipment in Ninety Eights. Sez the 1969 Product Selling Information Manual, "A 365-hp Rocket 455 V8, teamed with a Turbo Hydra-Matic 400 transmission gives Ninety-Eight all the smooth-flowing power it can ever use" <img src="/ubbthreads/images/icons/ooo.gif" alt="" /> <img src="/ubbthreads/images/icons/cool.gif" alt="" />

Only 455s hotter were the 390 hp L32 Police Apprehender and the two Toro engines. Some will argue Hurst/Olds, but the Hurst engine was raided from the Toronado and cop car parts bins. Besides- we all know the factory didn't install them <img src="/ubbthreads/images/icons/wink.gif" alt="" />

A nod's as good as a wink to a blind bat!

Raider I found that info later last night at 442.com . Because of many other things I'm involved in I'm not highly read on all the little differences in cars and models but its coming to me a little at a time just like everyone else learned. I was thinking all the older 455 4bbl had the 390 except 70 Toro GT and that the 2bbl was the only lesser. Then I read about the camshaft differences. How ever that page did not list torque for the 365 HP engine and that 510 torque spec is way higher than the Toro engine. Is that 510 for real ?Please let me know.

Scott I'm not sure what you are trying to say in your post. Also not sure how to take your comments. If you have some information to pass out I'm always listening . If you want to insult people do it face to face . These forums are about information . I really didnt get any from your post .

My quote above is from a "Monty Python" sketch (as is "Wink, Wink, Nudge, Nudge"), the point being that Rocketraider "winked" when he said that we all know the 455s were not factory installed in the HOs.

Wit and humor, dead on the internet. Film at 11.

The 510 lb/ft torque spec is accurate to my best knowledge. That was the magic of the BB Olds- ungodly torque on demand, and all in by 3000 rpm or less. Right where it could do the most good.

The cam and especially intake profile are why the Toro made a bit less torque than the 365. Bigger cams often sacrifice some low-end torque for horsepower, and low to mid-rise intakes make the most torque. The 66-70 Toronado intake is actually a negative riser for hood clearance.

The base 455 2-barrel was rated 310 horsepower, then a 340 hp version, then 365, then 390 for the B/C carlines. Toronado were 375 hp standard and 400 with the W34 cam package.Kinda weird that most of the B/C engines were rated thru single exhaust.

Of course the factory didn't put the 455 in the Hurst! "The Edict" <img src="/ubbthreads/images/icons/tongue.gif" alt="" /> was still in effect at GM at that time. Just because Pontiac got away with it in 64... why should we think the good Doctor Oldsmobile would have tried it?

Crafty guy, that Doc <img src="/ubbthreads/images/icons/smirk.gif" alt="" /> A man with a true understanding of power to weight!

Thanks Raider. It sounds as though that is the perfect engine for my 75 Convertable. I'll just need some dead end plumbing. I did know that when cams were used for more HP torque went down but that 510 is alot of torque. After reading tha article at Brycemans about the 1970 Apprehender I became even more intouch with my Deltas.

My appoligies Scott I really though you were calling me a blind bat ! Though I have been known to go after things straight ahead like a horse with blinders never seeing some important things on the way I have never considered myself bat blind. I am sorry - it went right over my head . You've got to realize there was no possible way to have known what that was about though.
