Cam match to intake

That cam has traded away off-idle torque for high rpm power. If it's running the factory TC,of course it won't pop. It may now have less pop than it did in factory trim. There are only two alternatives to this situation, A) a higher stall TC, or B) a torquier cam, or C) More compression, or D)I guess, put the car on a diet to loose 200+pounds, or E) skinnier tires,lol

I like that cam, but it's not for everyone. I think the 050 on it is about 240ish. That would be big for a SBM, but sweet in a sharp 440.
So the first thing to do in my mind is a compression test. Let's see how much cylinder pressure is in this ex-race engine.
I wouldn't make any purchases or decisions until this is known.
Except headers. If you want pop, you are gonna need them.
If you just want a cruiser, I would pull that cam in a heartbeat. But before I did, I would verify what it is, otherwise you might be replacing it with another same or similar cam,lol.And that would suck! That 284 needs headers and wants a TC over 3000. And then the whole pkg will not be real hiway friendly.
And If I was doing it and had the cash,behind those headers would be full-length,dual 3inchers,with an H pipe. But that would be overkill for a cruiser....
