Thanks! Unfortunately I believe it's cast.

Sounds good, I also just got info from Lunati. They say 138/369 is just fine, and that the cam can handle up to 500 lbs. He didn't think there would be any problems with the stock lifters either. Well, I guess I'll stop worrying and keep running! At least as long as no new noises appear.

Some new info I was just on the phone with a tech guy at Hughes, doing the best I could with my limited English lingual skills. They said 138/369 lbs is fine for their cams. They would recommend a spring with 145/358 lbs if the springs in the head weren't already there. The choice between their...

That's a good question. I don't know it the limitation is in the hydraulic parts or in the roller itself. I have heard somewhere that hydraulic roller camshafts have other style ramps, demanding very small lash settings if used with solid lifters.

Well probably that's the subtle sound remaining after startup. Would a "slow leakdown" lifter like HGH 5006S Hughes Engines be an upgrade, or are all stock style Magnum lifters limited to around 130/330 lbs? I notice that Hughes recommends both the stock type HGH5006 and the fast bleed HUG 5007...

Yes, they are all turned with the oil hole upwards/inwards

To clarify: I have them about one turn from zero preload. I haven't tried the other version, to almost bottom the adjustment out. I guess it can make them quieter (?). On the other hand it also makes an eventual "pump up" higher...

Its set about one full turn from zero. I have read that setting them just a bit from the bottom could be a way

They are bought here in Sweden. I would guess it's the same as the Speedmaster PCE

I do have a bit of noise even after start up, but not nearly as loud as on startup with some of the lifters drained. I don't really get what causes this. Is it the check valve in the lifter that can't cope with the pressure, causing the lifter to bottom out?

Hi! I have finished my 360 based 408 stroker with good result so far! I am however starting to worry about my spring pressure... The engine is based on a -89 roller 360. I used stock replacement roller lifters with the stock spider like plate to hold down the "figure 8 shaped" anti rotation...

OK, thanks My next problem is that parts of the plate are a bit rusty (the guy who took the engine apart didn't protect the parts vey well). Since it will have quite a bit of tension, I'm worried the rust spots may be crack starters... Do these plates ever fail in stock engines? Where could I...

Hi! I'm just about to finish the build of my -89 360 based 408. I am using a hydraulic roller Lunati cam with new stock-style hydraulic roller lifters and the stock "dog-bones". When I bought the block it was already in pieces, so I don't know how these are assebled. I have only worked on...

This story is still not finished... I ended up not using the block after all, since I already had the 4.030" pistons and eventually gave up trying to get them exchanged for 4.060". Instead I found a new block. This time a "pre Magnum" from -89. I also consider the roller cam a bonus. To make...

That's good to hear! Even if my block had been cast perfectly centered, I still wouldn't have more than 0.18" on cyl #4. With stock 4" bore, this would have been 0.21" thickness. With the core shift, my block had 0.195" wall on cyl #6 when new. I could turn the question around, If I start with...

Hi! I'm new to this forum, and start with a small block engine question. I'm building a 4" stroke LA 360 (408). Unfortunately, the -71 360 block I managed to find here in Sweden was quite rusty. It had to be bored to 4.060" to clear up. I have read all about the early 360 having extra thick...
