Any favorites of the various manufacturers versions of this cam. Melling, Comp or? Motor 455, 10:1, 6x4 heads 247cfm/180 @ .500, Modified 66 tripower, 4speed, 3.42, oversized RA exhaust manifolds. Don't want roller cam just a good HFT. Street driven 65 with occasional trips to track. Seen a lot of mention for Crower 60919.

I am using the 60919 with Crower Cam Saver lifters and its all you need for the street in my opinion. My engine is kinda similar to yours.

Melling SPC-8 is the real deal. Overlap sammy!

I too have similar combo, but I dont like the cam I have. Does this combo buck and chug in 25 mph zones in first?

[64speed]

No not at all. I have the TKO600 and it will pull 5th at 40 mph with no buck

One of the gents on here has mentioned that the Crower 60919’s that he has seen recently aren’t necessarily ground correctly, maybe he can clarify?

I used the Crane muscle car series 041 ...but that's been a LONG time ago.

seems I recall reading a thread that it was stated all 041 cams are pretty much the same, most made by CMC. blue ta

The Melling SPC-8 is suppose to be an OE replacement. Probably gets my vote if you want a RA 4 cam. Side by side comparison the SPC-8 I have had used a different cam core with a wider lobe. It’d been 6 years though, I don’t know if that is still the case. CMC grinds the Melling, Compcams, Edelbrock, Lunati and Summit 041 grinds. Specs are the same as the Melling, but I think those others that are not OE replacements use the normal narrow lobe core.

The Crane and a Crower 60919 both are different than the Melling. Crower is more aggressive, Crane is less aggressive.

I prefer the Crane "Blueprinted" version

X2. I agree, I think it is top dog of the RA4 grinds. Sucks that Crane is no longer around.

I was just going to say the same thing, I know a lot of folks recommend the Crane version but they haven’t been available for a few years, I wonder if you could have one custom ground but then I question what makes this version so much better than all of the other 041 choices like the Melling, Crower, etc

The Crane version has a bunch of assymetric’s in the design, and shuts the valves a lot more gentle. The way it is ground it should have the broadest power band of those grinds.

The others are more symmetrical designs. Opening and closing ramps are the same.

I used the Crane blueprint version about 20 years ago and it is still running very well.

Identical to the Crane HIT 284281 "High Intensity Series" and later "PowerMax".

Yep. That’s the one. There are a couple cams that are close in specs, but don’t appear to be exactly the same. That 294B Crane could be the same. It does look close.

Two profiles in HP series sure looked close too. I think I remember being told they were different.

This is the cam that Jim Hand had in his 455. Likely still in the engine. Seemed like Bullit made it for him.
Is Bullit still in business?

Thanks, All, for this thread.

I bought one of the Crane 041 cams, years ago, from Paul K, Hope I still have it (long story)

Merry Christmas!

I think I remember Jim Hand tried to have Bullet copy the Wolverine cam and there was something about it that they could not copy. I mentioned it in that other post. That cam was something they came up with at Bullet that was fairly close to the Wolverine. (Insert Paul K’s comment what is a few thousandths and a couple of degree among friends here) IRC, that person behind that cam may have been John Partidge. I think Jeff is correct, it is still in the car.

Stan or one of the other guys likely knows more on core specs than me. But I think the .56” core width listed for CMC cores for Pontiac, IRC..is the width at the base circle where the cam core was roughed in at. It varies and is hard to measure. Whatever the width the core was over the nose will be the same no matter what the lift is. The base circle can get wider with a higher lift profile. If the core was from EPC the cam will have EP1 cast into it, along with CWC. EP1 will be cast into the opposite side as CWC. CMC core only have CWC cast into them, the cams from comp could be EP1’s. Comp uses a lot of EPC cores.

I think one of the SPC-8 cams I had that had the wider lobes is at a friends shop. I might be able to get some measurements off of it, I recall it had .560” width over the nose. If you compare that, with just rough numbers to a cam has .48” over the nose the narrower lobe is loosing about 20% of the contact area. If that is a general trend for cores right now, it makes a person wonder if that is another part of the issue with cams going flat these days.

I know of a Compcams 041 that went flat during the break in a few weeks ago. I”ll have to check with him and see if I can get him to measure the lobe width. I bet it is those narrow lobes. It had HLJ lifters, but got broke in with the single springs that come with flat tappet E heads and 1.65 rockers. Which was close to 280 lbs over the nose, 30 years ago the probably would have been fine.
