Default Which intake manifold??

I just recently purchase a junkyard 5.3 for a project of mine and the intake manifold has a big hole in it from them pulling the engine out. My question is should I just by another truck manifold (ported ) or LS1 manifold? Maybe an LS6 but it's not really in the budget right now. I don't know how much porting a manifold costs though. So here's my build

1989 toyota pickup
straight axle swap
4l60
4.88s
40" boggers

It is a cruisin/mud truck. My plans are for heads cam later once I get it running and the bugs worked out. Would the truck manifold be better in this app. would the LS1 or LS6 work out better in the long run? Thanks for all input

For what your doing and the tight budget I see no reason to not just grab another truck intake up, and down the road if its in the budget you can upgrade to something better.

ls1 intakes are dirt cheap and there are soo many of them from people going to ls6 intakes which are harder to find at a cheaper price because LS1 guys like me want them. Id say ls1 would be fine but if you find a good ls6 for a fair price go with that.

Thanks guys.
Is porting an option on a Truck manifold and would it be worth it?
Will an truck manifold make descent power on a cam only or heads/cam app or would it hurt it? Probably going to go with the truck for right now seeing as they are inexpensive. Just trying to find out how much potential they have.

just get another truck intake if you have the room.get the correct yr .I feel porting is not worth the cost unless you do it.save up ls6 or a BBK/weiand ls intake.
