I think it's more accurate to say it's different performance rather than way better performance.
But, you' d have to try both to know what I mean.
Whichever one you choose, you're still likely to get run over by a *** buzz bomb with a fart pipe on it.

Good info on this thread. I've been looking for a replacement cam for my L76 which currently has a Comp Cams 270H 
installed. Just ordered up ELGE904PMDL from Competition Products - it was still in stock. This kit includes the direct lube solid lifters.

I bought on a few months back from Howard’s cams, original 1970 specs AND it is “parkerized” like they were when new.

The second design 327 springs, 3911068 (Sealed Power VS-677) are good for at least 7000. They went into production in '67 and used at least through '79. Remember, SHP cams, both mechanical and hydraulic lifter used the SAME valve springs as base engines.
Seat force is low eighties pounds and about 200 open. If you have a real LT-1 cam, manufactured to the GM blueprint, that's all you need. Higher force springs will just increase the probability of wiping lobes, but these aftermarket outfits always want you to use gorilla springs, which is an utterly clueless recommendation.
Set them up with .090-100" coil bind clearance and they are good to 7200, but you need massaged heads to have usable power over about 6500.

I'm on strike two for scoring an LT1 camshaft. Now the Ebay seller contacted me to say they are refunding my payment.
Anyone have a source for the LT1 cam?

Here is one though,
Not an LT 1 but an Elgin copy of the GM 151, about a step down from the LT 1 but still a very nice hyd street cam.

out of stock
So, I called Comp Cams today 3/26/21 and he said "nope".. before I even got all the part number out of my mouth. He checked in the Howard cams book too and they are not in stock...Seems like the manufacturer is not up and running.
