HI, NEED SOME HELP I`M LOOKING @ A 1966 TORONADO ENGINE #389244D ,CAN SOMEONE GIVE ME SOME INFO ON WHAT ENGINE & SPECS MUCH THANKS

 

HI ME AGAIN MY OTHER ? IS WOULD THIS ENGINE& TRANNY FIT IN MY 72 CUTLASS THANK S AGAIN

 

That's a D-block 425. If it was born in that Toro then it has high compression and big valve B heads. Not a bad choice for a Cutlass.

 

You could always get rid of your Cutlass and buy the Toronado. They are definitely COOL!

 

I don't think the transmission will work. Toronados were front wheel drive so that is actually a transaxle.

 

hi it`s me again can someone help me out with the torque& hp on the 66 toro thank you

 

Factory rating was 385 HP and 480 ft-lb, but don't put a lot of stock in those numbers.

 

hey joe when you say don't put a lot of stock in the numbers ??were the numbers low or high, I have a chance to pick up the same motor(389244D) out of a 66 98 and wonder if its worth it? any input is greatly appreciated

 

The hp rating would be high by todays standards. Today all hp ratings are net with all accessories, factory exhaust, etc. When the ratings where done for 1966 it was on a dyno stand with open exhaust and no accessories. This is a simplified explaination and has been discussed many times in the fourms. Hit search and you will find lots of detail

 

agreed!

 

Any 425 is worth getting, but the reason I don't put a lot of faith in the stock HP numbers is that they were biased in both directions. As noted above, early (pre-1971) motors were rated at gross HP, without stock air cleaner, manifolds, or accessories. That would normally make the ratings higher than the as-installed delivered HP. I say normally because there were some funny things going on with the highest HP engines. As an example, the 1970 W-30, with different heads, more radical cam, and O.A.I., was only rated at 5 HP more than the normal 455 (and significantly less than the Toronado 455, with a much milder cam!). A suspicious person might think that the 370 HP rating was more a function of GM's 10 lbs per HP limit (370 HP max in a 3700 lb car) than a real dyno rating.

 

thanks for all the great info, Warhead I am having trouble finding a conv Toronado??

 

I'm running the same block with B-1 heads. Very happy with the performance.

 

AZ , Nice ride , i need to post some pics, which cam are you running in the 425 engine or is the engine stock ? thanks for the response

 

Althow I did not do the engine build, the previous owner informed me it was stock with a W-30 cam or rated the same. I don't race the car but the HP is plenty for me. I have a buddy that has a dyno and hope to get it on next spring.

 

anyone have suggestions for a cam & lifters for the 425, based on the info here sounds like I have the 45 degree cam angle, veh will be driven on the street, for right now running Qjet carb,and factory dist , w30 exhaust manifolds and turbo 350 trans thx for any info

 

You may want to remove the intake before ording any parts. Mine is a 38 degree CBA.

 

Looked for this earler. but here you go

 

awesome I will check it out , thanks

 

Nothing that a sawzall can't fix.
Do you think anyone here, who has photo shop could give us a preview of one?
How bout a 78/79 butlass Cutlass convertible?
79 Starfire convertible?
Any 65-88 Cutlass wagon convertible?

As long as the 1970supreme is not covering up a perv.
Jim

 

ummm yeah yeah they made a vert... ok they didn't but it might of looked something like this if they did LOL


somebody suggested photoshop

 

COOL!
How about the others?
Jim

 

ok how bout the 78 cutlass...

LOL... actually there was a vert riviera and tornado in the early 80's?

 

Yes, but they were not factory built, they were aftermarket conversions (ASC or Cars and Concepts, if I recall).

 

Hi AZ442, think you mean 39 degree CBA!
All toro did have that 39 degree CBA big lifter engine , all other 45 degree CBA small lifter engine for that year.

 

That looks better than what the factory put out.

The 39 degree 425 is a keeper.
Great engine.
Jim

 

Does the 455 come in 45 and 39 degree?

 

the 455 only came with 39° like every other olds engine build from '68 and up.
