I agree with carackedback on the intake, but have a question regarding your cam choice.
Which Purple cam are you talking about (duration/lift)? That 360 has very low compression and even with machined heads it won't be great. That RC is heavy and needs a lot of low end torque just to get moving. With your tire size if you have 3.23 or 3.55 gears a 284 degree cam will make it a real slug.

i intend on putting 4.56 gears in it..they have 3.55 on 35-12.50- 15 but may drop the tires size to 33's

the cam is a 268/272duration and .455lift

My '87 has the Comp XE262 with 901-16 springs, Performer 318, and pretty much stock factory everything else. I wouldn't use an MP cam myself but if it's small and you have it... Otherwise, it's a truck. I don't think Mine's seen the high side of 4K rpm in 5 years. It's basically idle to 3500, and the intake is fine for that.

Edit- it's an 87 360....

thanks for the info it helps trust me...lol

I'd run any OEM 340 or 360 four barrel intake. It would be better. But like above, I'm sure it will work.

i have the LD4b on the truck already running and would have to look for another intake which i was thinking anyway

Yes the LD4b is actually a VERY stout intake and would work just fine in a heavy 4wd vehicle with J, X, rhs or ede's. Essentially, IMO, searching out a different intake is a waste of time, money and resources.

The guy asked for opinions and I gave mine.

There are a few that have gone mid 11's on 340-360's with an LD4b with not much in the way of camshaft. It's a good piece. I thought I laid that out in response to the PM you sent me a few hours ago. I don't feel offended because there is a contradictory opinion in the thread.

Is that better? no need to respond it was rhetorical....

I'm done. Have a good one all

still i am replying...lol thank you sir for the info trust me any info helps.

even though i am an ASE master tech i just really know stock stuff or what i need to know to get the job done. i have limited experience with working on anything performance wise that wasn't bolt on. so i thank you for your input.
