Olds 455

'68 4-4-2 that was found in a barn. Disassembled an original engine from '69 Toro and found no measureable wear on any of the surfaces. Slapped it back together with gasket kit, mild cam and Performer intake. Not rebuilt. How cool is that? Best 1/8 run is 7.8 sec at 91 mph with 3.08 rear.
Found THE original 400 engine in a shed with roof caved in. Found the original TH400 in woods on next property. Found exhaust manifolds buried in dirt but somehow still in pretty good condition. Found the original 3.42 in the woods also.
Need to find 1/4 mi strip close to Charlotte.

pretty sweet that musta been quite a property w all that stuff lying around !!

7.9 sec in the 1/8 would be mid to low 12's. Your 7.8 is low 12's easy

truckman5000

Nice great job, what cam and timing specs are you running?

wr1970

Sorry you are dreaming! A bone stock toro engine will not make it even to mid 12's. I doubt even in the 12's. JMO

TripDeuces

It's not bone stock. He said he put a mild cam and an intake on it. 12's are very doable.

wr1970

I still say nope! Again this is my opinion.

olds 307 and 403

Everyone times can be very different. I would need the to Pope to bless it to run 12's.

gs72

12.99 is still in the 12s. Lol

7.8 in the 1/8th mile with a near stock 455, with 3.08 gears, in a 3500 lb car ?! Are you running nitrous ?

Kennybill

7.8 second 1/8 mile is equivalent to a 12.17 second quarter mile. The 1969 Toronado engine is right with the top preforming Oldsmobile 455's. The 0.921 lifters are a little pricey. Jmo, the Toronado factory intake is a good intake but heavy, great in a G-body for hood clearance, the Proformer intake is lighter and probably a better flowing intake but not as much over the Toronado as one may think. I also would like to know what camshaft. I wouldn't change anything if I could get this time with a 3:08 gear.

wr1970

That is because you can't understand. It will not happen i don't care what your 1/8 mi is. It will not make it into the 12s without doing something more than what the op stated. Again this is my opinion.

Pissing contest, funny. I'm waiting for Joe P. or Oldsmobile Dave to put the #'s to it. You know, just for fun.

There may be a formula missing between the 1/8 & the 1/4 finish. Depending on your build of course. Happy Fri. boys; I'll have another one for us.

Tirekicker

Amazed, the original author, no more post in his thread. I say its a 13 second car at best, realistically, 14's

Kennybill

Oh I understand, I was trying to say in a nice way that I can't see that time from that combination. The modification made to the engine aren't going to effect the performance to get into the low 12s. I've drag raced enough to know about where that combo can run. The factory "stockers" such as Hurst Olds couldn't run a 12.17, and believe me they were prepped by the best mechanics Oldsmobile had. Maybe I should have been more blunt in my first post.

Kennybill

Here's an example of the 1968 Hurst Oldsmobile. Jack Watson knew performance and I'm sure this car had the best of everything including the tune up. Everything is "fresh." Motor Trend June 1969
69 Hurst/Olds (Auto)
0-60 5.9 sec
1/4 13.98@101.28
3.90 rear gear
8-12 mpg

Road Test Aug 1969
1969 Hurst/Olds (Auto)
1/4 14.08@99.88mph
3.91 rear gear
10.6 mpg. https://redirect.viglink.com/?format...layer_embedded

This chart says that you are correct.



http://www.pro-system.com/calc.html


Using this chart a car that runs 7.8 ET in the 1/8 mi will run 12.17 in the 1/4 mi.


I am having a hard time accepting that a bone stock Toro engine will push a 3800lb Cutlass to a 12.17. Take it to a 1/4 mi track and see how it goes.


Good luck & congrats on the success so far.


PS....are you sure that your 1/8 mi time slip is accurate?

TripDeuces

My numbers can't be disputed because that's just simple math. 1/8th to 1/4 comparisons are just a linear equation.
I think what people are having a hard time with is believing that his car does 12's. I agree that a stock Toronado engine dropped in that Cutlass won't do 12's but he already stated it is not stock. My stock 70 Toronado did 15.8 in the quarter. When I took it out of the Toronado and dropped it into a 70 Cutlass, added a mild cam (.490ish lift and 225-230ish @ .050), an aluminum intake, 780 Holley and headers my first pass at the track was a 9.60 on L60x15's. Putting 8" M&H slicks dropped it to low 8's and minor suspension tweaks and air bags put me into the high 7's.
He never once said it was stock and his times bear that out. Of course he also has never told us what other things were done.

Kennybill

He "slapped it back together" with new (thicker) gaskets, and 3:08 gears. Okay, I learn something every day.

Bernhard

The 455 has the HP/TQ to put the car into the high 12's
Headers with header mufflers
A Good fuel pump
closed diff
mild converter
Shift kit
3:42 okay 3:90 better
sticky tires
free flowing air clean
air bag
70/30 front shocks
The worn suspension will aid in weight transfer
I would think it would need all of the above to run in the 12's

If you are close to a 12 second run here are a few tricks that can make the difference.
Ice intake before the run this is not legal at a lot of tracks because it can put water on the track.
Loosen water pump and alt belt.
Sept/fall air
lighter rims

Tuning suspension for weight transfer so the car hooks is a must.
Carb and ignition tuning is also a must

GEARMAN69

I have know doubt it could hit 12's with a 69 Toro engine either since they have good compression and decent heads so the simple bolts could easily have the power. My take is the 91 mph claimed . I know my eighth and quarter numbers well as I have doing it 30 years and get the short times at Ennis when I run quarter. A 7.8 is totally low 12's. My heavier wagon went 7.9 and 8.0 w 12.5 and 12.6 106 at only 85 86 mph in eighth. That 91 is an 11 sec kind of number potential like what a 7.5 car runs 11.6-8 range around 112 mph . That would be quite impressive but so the car might be gutted out and the guy maybe a pretty good tuner and driver Would like to see more from OP too. For the record I think the upper 12 with a low 8 is more believable , the high mph is red flag to me mainly. Was this a legit timed track pass ?
