you can use straight lifters but the offsets clean up the pushrod angle some.

Here is a pic:

When using the offset lifters you may have to clearence the 4 casting lugs in the lifter valley near the block deck for pushrod clearence.

On a 400 low deck with Indy 440-1 offset intake rockers, this is what it looks like.

And this is a pic of the grinding on that lug to clear a 3/8 pushrod, offset roller lifters, and 440-1 offset intake rockers.

My 440-1 heads on the low deck with non offset solid roller lifters didn't rub on the low deck block but they did rub on the heads when I switch those heads to the 440 block I had to trim some material off of the heads

Yes, we have been saying combining a low deck, 440-1 (or B1) offset rockers, and offset roller lifters. You didn't have all of them.

Sometimes you get lucky and sometimes you don't I did notice on the 440 block that the 7/16 pushrods are very close to the block lugs. I forgot to mention, I think, that the low deck motor had 3/8 pushrods and the 440 motor has 7/16

This info applies to B1 Engines also? How should the offsets be orientated?

Re: 440-1 head user what roller lifters - 02/26/11 01:45 AM

Is there a price difference between the offsets and standard lifters?

Re: 440-1 head user what roller lifters - 02/26/11 05:04 AM

I used IMM's / comps deal and I believe the price was the same either way(i use offsets).... I check the oil band cutaway tonight with my new cam and it isnt sticking out the lifter bore bushing...

Re: 440-1 head user what roller lifters - 02/26/11 01:33 PM

Sledge,
How much lobe lift is your cam?
I think his design is good for at least 0.460" lobe lift without bushing the lifter bores.

Can you measure the cut away location and size?
The dimension C1a is the cutout on the side for the wheel.
And dimension d is the depth of the top of the pushrod seat.

Jim here is a couple pics I took last night...I had talked to brian and couple other people as I was concerned about this due to possible too much lobe issues and uncovering the cutaway....at full lift the oil band cutaway is still down in there a good ways(see ruler pic/black line is where cam was at full lift)! I have a world aluminum block RB(race version)... my lobes are .485/.471 hope this helps... pics are from iphone so hope its clear for ya

Re: 440-1 head user what roller lifters - 02/26/11 02:44 PM

Those pictures are good. So .485 lobe lift with your cams base circle and a bushed aluminum World block look fine with the IMM roller lifters.
I think those are a great design.

It looks like the top of the lifter is below the top of the lifter bore at zero lift.
And the lifter sticks out roughly 3/8" at max lift.

if it matters I forgot to mention the oil hole in mine is parralel with the lifter galley and the hole in the lifter is at 2.5" on the ruler pic right above the cutaway

Yes, Brian mentioned that to me before, to avoid excess oil flow, not direct to oil galley opening. Which doesn't matter if the block is bushed.

This old pic from Brian must have been a prototype, because yours looks like it has a taller section above the cutout?

Our low deck with B1's didn't hit the block with offset lifters.

Allen,
Did your factory low deck block have these casting bumps under the intake ports? I can't see behind the pushrods in your picture?
It could just be close due to manufacturing tolerances.

No actually they are just rounded all the way down. Wonder why.

My low deck (400) Indy Maxx with offset lifters required block clearance. There was also a problem with the FelPro 1039 gasket interfering with the pushrod.

I use standard roller lifters on my low deck with -1 heads and a 706/661 lift roller, Harland 1.5 rockers.
