.039 is great

Oh and I have poly locks

The locks you're ordering....

When you have the retainer pressed down and you put them in place they have the annoying habit of falling down just as you're raising the retainer to lock everything in place.

The LSM tool should make that very easy as long as he doesn’t go too far. He should be able to adjust it so that doesn’t happen.

Just in case, I’d cover all oil drain backs and the whole lifter valley in case anything drops or goes flying.

If he uses the good LSM tool he will be just fine. I have never put anything on mine when I do them. I also don't see oil or grease being a problem. I drop them down into the retainer then lift the spring and retainer up as I release the pressure on the spring. Have never dropped one doing it that way.

7.70 or 7.75 is going to be fine. The width of the mark on the tip needs to be less than .07" from what I understand

I don't do it that way anymore, I have used Scott Foxwell's method and it works just fine.

Come-on, usually around 50 years old people hang the old tennis ball on a string from the ceiling so they don't pull the car in too far.

I was driving my mothers SUV one day, brought it home in the garage for her, and went back and forward hitting the tennis ball!

She just got back from Walgreen's ... there's about 5 feet behind the car.

I used foxwells method (sort of) to come up with that length. Then checked anyway!

 

[Steve439]

I use the LSM and I still fumble the little fuckers without some grease!

I may be a pretty poor mechanic...

I couldn't get exactly that close without getting out of my truck and adjusting about ten times.

Good job.....never scratched the shovel!!

 

[Briansshop]

Have used the TFS push rods on several motors,no issues. Spray some brake cleaner in them and blow out with air.

 

[Mark O'Neal]

I stick with Smith Bros and Manton, for those that want to brag about how much their pushrods cost.

This is one of the reasons I find this thread so uplifting. Because I have BBC/OEM stuff, I have zero idea who manufactured my pushrods. And yet, somehow, my stuff continues to function. I thank G*d my dad bought that Impala instead of an LTD, so many years ago. Take care. Tom Worthington

Can someone make sense of the engineering behind this, with none of the centerline on the valvetrain lining up. These are rough estimates.

The lifter bores in the block have a 1.725 centerline spacing

The pushrod holes in the heads have 1.960 center to center

The afr pushrod guides maxed all the way out have 1.812 center to center

The rocker studs are 1.788 center to center

The valve tips are 1.862 center to center.

I just don't get it. How does this produce proper geometry?

 

[Briansshop]

^ Yes. I have AFRs and could not get totally happy with the rocker alignment. Not enough guild plate adj,and a small hole for the push rods in the head. The roller doesn't have to be centered L/R,just get it as good as you can and lock them down.

If only things would just go my way. Found some shit while looking over the oil pump

 

[Low & slow]

Wow , I’d make sure the bolt holes on the pump line up with the holes on the pickup tube , what brand pump is it ?

 

[Patriot Racer]

Too much tq. You have a Harbor Freight Tq wrench?

Buddy of mine snapped off a bolt on his brand new FTI transmission while bolting on his bellhousing. The directions that came with it were for a C4 instead of a Turbo 400. The TH400 has smaller bolts. He went straight to the Tq specs without paying attention and snapped it off. He ended up taking it to a machine shop and it cost him $800 because they had to make a special jig.

Be happy, it's just an oil pump. Cheap to replace.

BOOOO!!!! That sux!
