I had my intake cam reground/welded/hardened by Delta Cams.  I can't remember the price of the top of my head, but you might find prices on their website.

My intake cam is at Delta right now for basically an S50 copy. Looking for as much lift/duration without welding, just doing a base circle grind. I should have exact specs later this week.
I plan on doing a few thing to benefit the community with this so I will be installing a few things in order on my tired M42 to see the difference. First. I will install my LTW and clutch. Then, I will swap on my DISA manifold with a manual vacuum control to see the difference. My gut tells me it will flow better than the E30. Air doesn't like to stop, and the smooth bends and generous ports might actually better on the top end. Torque will be better of course. Finally, time permitting, I might put the cam in my old engine to try out too. Whatcha guys think?

Ok. SMF conversion is done. 12.5 lb flywheel is still too heavy IMO. But it is much revvier and smoother. Like others have said it's not like night and day. Parts used:  M20 flywheel lightened balanced and surfaced. Stock 325i clutch Assy. 325i bolts. Late 325i starter. Euro 323i TO bearing. Since my flywheel was machined on the back I did not use a shim behind the flywheel. I think that would be a bad idea anyways since it could compromise a perfectly flat mounting surface. Eng block to ring gear distance is identical. I highly recommend this IF it can be done inexpensively. I think it cost me around $300 total with machining and lightening. Drop $500 on this and you might be disappointed.

Nice!  I did some nice upgrades when my engine was apart, but did not replace my pistons.  To this day I regret the shop that was used for the honing and the fact that I reused the pistons.  I think there's a loss of compression.

Do it once and cry only once.

Bottom end is done. And I did a little mock-up with the head and manifold.

Awesome, looks good glad to see this moving forward! 12.5lb flywheel is a huge improvement over stock.

Small update. Head and exh manifold are on. Note that the victor reinz head gasket is barely large enough to clear the 86mm overbore but there are no interference issues yet. We'll see when things warm up.

Glad to see things moving along.  Did you coat the exhaust manifold with ceramic?  I had mine coated with a black ceramic layer.  It's held up perfectly for the past 6 or so years.

It's a ceramic coating/paint from VHT. I've used their flame-proof paint for years and it always delivers. I painted the headers on my 510 with this and it held up very well.

Probably won't see a M44 intake sprocket with a M42 exh sprocket together often but this engine is ready to run on either DME. Intake cam is in and both are installed and timed. Intake cam is 212deg at .050. 388" lift. I'm not sure what this translates into for advertised but I intend to check it all wit a degree wheel soon. Will find out then.

Hi
Does look a bit odd, single or double row chain?
Cheers

Stock double row from the M44. I'm surprised it works with an M42 head since the cams bolt in differently, but it all lines up.

Here's that 'big' cam:
