From memory that cam is the crow 4502 which is supposed to be the bees knees in a stock 5.0
But I heard the mace memcal tune still leaves a bit on the table and would benefit from a Dyno tune.


I am running that same cam (which I also got from mace) in a moded 5.8ltr, but I haven't tried their tunes myself.

I'd be looking at one of the lunati grinds , newest technology on the market and they're quite different on paper to the run of the mill crow and crane we've had the past 25 years.

I’d tend to stick with an Aussie company for an Aussie engine. The Americans are unlikely to put in the R&D for an old 304 that wasn’t available in their own country.

I've got a MACE chip and it gives me a fair bit more power, especially mid range. I'm happy with it for the road, but I'm not looking for max power.

How much r and d do you think was done specifically for the 304? You don't think maybe they found some things that worked , why they worked and did other things similar to fill the gap?

With durations similar to each other you've only got timing and lift to worry about. The new love profiles by lunati have more lift than the old crow and crane.

They also have reverse and standard split. Reverse to help the tpi style banana intake manifold cheat the low compression and out of breath.

Or the other direction because cold air flows easier than hot air and the VN exhaust ports don't work as well as intake.

They even do straight symmetrical grinds.

Almost every single camshaft if you look at the timing cards for a Holden is based on SBC opening and closing and just with some duration difference in the middle no-how.

Do you have the same kit in your car if so what does it sound like is it lumpy

Not the cam, I've had the car for 28 years and I want to keep it for a while yet- the factory cam is OK by me.
It does sound a bit lumpy with the Redback exhaust, the teenage blokes fuelling at the other pumps in the servo keep asking me what's in it.

My cam (same as what you are looking at) has an okay lump in my 355".
It should only be MORE pronounced in a 304"
