425 Intake Manifold
Will an Intake Manifold from a 455 fit the 425 from a Toronado? I know the 425 and the 455 are the same but wondering if the Toronado's were different then the regular 425, as far as bracket and things go, I would like to keep all the brackets original. Thanks

I'm not an expert on the matter, but I know the Toronado's had a Low-provile intake manifold. And sticking an intake from a '455 that is NOT from a Toronado would likely create hood-clearance issues. But, if you have a Toronado 455, then I don't know about the brackets
But it should clear the hood.TOA #839

- Years Owned: Owned a '69 back in about '77, this cat was a legend in the Nebraska panhandle, it was very fast even for it's size. It would absoloutly fog the front tires from a standing start; I don't mean spin them, I mean just boil 'em from a standing start for at least 100' (measured)! I know what you're thinking, they weren't old rag tires they were modern Yokohoma radials. I'm sure this car would have ran 150mph too because many times I had the cruise set on 135 with 1/2 the gas pedal left. BTW this was in the middle of nowhere Wyoming.
I'm finally about to start work on my '66 that I've owned for 10 years. I plan to make sure my '66 425 runs just as strong as my '69 455 did. I hope to be doing some write-ups for the Driver as I go through the '66. I'll be updating it with disc brakes, electric fans (gasp), good stereo system, battery in the trunk etc., etc. as time and money allows.
I also may be building some new wheels with the correct offset, etc. - Location: Hastings, Nebraska
Re: 425 Intake Manifold
Yes the Toro intake manifold is a low-rise unit and you can certainly use a 455 manifold But you will have hood clearance problems.
The Toro intake is a low-rise BUT Olds engineers designed it with a larger cross sectional area to make up the performance difference.
IIRC you can read about it in the tech archives here on this site.
