I just ordered one from them...and received it today. The finished machine work looks good to me. Are the seals of good quality..or could I improve on them? If anyone has pictures of the holder installed on the block,I would REALLY appreciate it! Thanks in advance! Randy

He makes the alum mains for Best,main gurdles,hemi rockers,and is doing all the machine work on the new mopar blocks. He really does some nice work. I have his car here now redoing the trans.Jake Last edited by JAKE68; 04/20/12 09:02 AM. JAKES AUTOMOTIVE

Even the engine builder couldn't see any differences but we could not get that Indy one to stop leaking. Tried different seals and even machined it a tiny bit to get it a little tighter. It leaked so bad I had to use a rag and a coat hanger to keep oil off the track. I used two rags per race. Nothing worked until I replaced it. I'm sure there are plenty of guys using them without any issues. Maybe mine was manufactured on Friday?!?!?

But if you have an aftermarket block MP/World, check to see that it does not interfere with #5 maincap. The 512 I have now needed clearancing on the retainer; so I used the retainer that came with the block. I have never had a leak using them on the 470 and 528 hemi that I built a few years back. Plus you can buy replacement square O ring side seals seperate from Mancini. www.picturetrail.com/hemi_ram
