Hey
Its been some time since I have been on here but I'm the guy building a 455 for a 78 regal. I am waiting on the heads to be touched up after the 8 months it took me to port them.
Well I found a 66 (i think) toro at a salvage yard, there are lots of nice parts on there, I pulled the motor (by myself in the dirt!!!) and was wondering where I can find an id chart to c what the motor is. B heads and forged crank, 400 or 425?? just pulled cuz I could not bare to c it crushed, and also wanted to let anyone interested know incase they are looking for parts

Thanks

 

Its a 425, sounds like a great find.

 

I took the heads off last night and found 1 cylinder a lil rusty but may be so lite a hone will take care of it. It has the 1 piece rocker arm retainer, big valves, good D and E manifolds but I think it is a 39 degree with large diameter lifters.

 

The toro had a 425 in 66 and 66 and it would be a D block. B heads mean 66 vintage with large valves, larger lifters and a 39 degree cam angle not the 45 degree that regular non toro engines had.

 

Has anyone thought of using the stock roller lifters and retainers from a late model 307 in these blocks? I know you would have to have a cam ground for it, would a cam guy not be able to grind a 39 just as easy as a 45? The retainer plate from the 307 bolts exactly in place of the big block cam oil shield....I'm retro fitting stock chevy roller lifters in my 455 is how I know but if you could use the olds rollers it would be easier...something to think about

 

Sorry fellas antbanks78 is actually me, I just haven't logged on in a while and forgot Log in id

 

Just to clear things up a little,,,, the modern and most common cam angle is 39 deg not 45 so there are plenty of these around. The Toro uses a larger lifter and I think the later model 307 engines even the roller ones use the small lifter... so they will not work in the Toro block at all.

 

No the late 307 use .9something inch roller lifters...they are to big to fit in my dads 403 and to big to fit in my 455...i have not put a roller lifter in this block but i have a set and if you like I will take a picture?? I have a set of chevys and olds rollers and there is a big difference, I wish they were the same size so I can use the olds retainers, I have to use the chevy retainers with one side cut out because olds lifters are farther apart than the chevys

 

I did not know that... and never heard of someone using those rollers in a .921 lifter engine. The Toro 425 would have a .921 lifter bore.

 

i just took some pics of the olds rollers in the D block and next to a chevy roller...let me figure out my photobucket thing and I will show you, but only problem is lifter bore is a lil short so still have to make a bushing to extend the bore because the lifter has a notch that goes above the bore and let oil out.

 

307 roller lifters and retainer in a D block 66 toro 425 fit quite nicely




last pic is of chevy roller next to 2 olds rollers with retainer...if you keep looking in the photos when you click on the pictures you will see some of the stuff I am doing with my 455, mostly fitting chevy rollers to it

 

I noticed that the pushrods were going into the lifters at an angle, is that an indicater of CBA...if so is it 45 or 39??
