Any one have a set of Johnson Hydro Roller Lifters for a BBM in stock?

Thanks for the help - Mark

You could try Panella's in Stockton. They have a pretty good Mopar guy there.

Brand New, never used. Goodson part number HGR-3410.

$200, including shipping to an address in the contiguous United States.


Thanks for looking -- Mark

Yep. But worth it.

Larry, is that valve drawing worksheet available in one of your software packages? Sure would save me some time.

I am sending the rods to pankl not just to have them size checked but also to have them stress checked, to make sure they are still usable and not beat to hell and back from a nascar team. They told me that they would "recondition the metal" to bring them back to life if they are worn out...

I think something in the range of an 1.875 to 2.00 stepped primary would work. And a Merge collector with a 3.00 choke and a 3.50 outlet. Just my opinion. But I would bet it would accelerate better with the smaller tubes. As a side note, most 400+ ci sprint cars & dirt late models use 1.875-2.00...

Welcome to speedtalk. Completely off topic, but wondering where you are located, as I've never heard of a barometric pressure that low.

I'd like to see a little more compression height. With a 1.00 compression height, the top of the rod is darn close to the underside of the piston, which puts a ton of heat into the small end of the rod. Also, the valve pocketing with a 2.250" intake valve might require the top ring land to be a...

.020 should be sufficient assuming your piston to wall clearance is in the .0020 - .0025 range.

If you have the time, the best way is to send the head in to T&D and have them fit it correctly. I've done a few of the Eddys before, and all of them have different stands. T&D will need a cylinder head (preferably with the valve job done), and an intake & exhaust valve that you will be ...

I have found Pipemax to be pretty accurate on American V-8 engine. When doing 4 valve automotive and motorcycle engines, not as accurate. Can't explain why, but the 4 valve stuff seems to come down to experience and trial and error.

That's getting tight. At that point, you need to do some math with your cam to see how far each valve will be open and at what degree they will be at the same time. There's no yes or no answer without knowing those factors. To add to this, set the valve lifts at overlap, where the valves will be pa...

If you have the extra cash, do the aluminum block. We have swapped a few aluminum blocks in to replace iron, and the biggest loss was 30hp, and that was on an 1100hp BBC. The SBC have been between zero loss to 15 hp loss. A current SBC aluminum block weighs in at between 95-105 lbs depending on whic...

It is not very clear from your original post what size bolt you need.
