I've got my hands on a 4.8 for free (traded computer skills) and I'm thinking about putting it in my miata with a t5. I'm guessing curb weight under 2500. 4.8 came out of van that was running with 150k miles. Dude upgraded his 3/4 ton van to a 6.0.
This isn't my daily or anything so I don't care a lot about drive ability.
The thought of an 8k rpm v8 in my miata gives me a tingly sensation.
So I'm thinking about porting the heads and upgrading the valve train, alot. .590 lift, a 224/232-degree duration split at 0.050 and 115 LSA for a camshaft sounds good? I stole the specs from super chevy. Any other suggestions?
This is on a budget.

I realize my fabrication skills getting the motor in and ford 7.5 irs in will be the most difficult part.
I'm mostly just wondering what would be the cam options.

That's where I stole the cam specs. They don't say anything about the bottom end or anything... just needing more spring pressure and they rev to 7500.
I was thinking maybe a trunnion kit and good springs would get it close.

That a Crane #1449121(224/232 115lsa+2.5, ivc is 44.5, overlap -2*) fairly mild cam lobes a with a 56 I/55 E ramp rates. I'd highly recommend sticking with mild cam lobe like these if you want to spin it above 7k rpm.

It's very similar to the Cam Motion, Blower Stage 2 cam.
