i am planning on getting a set of heads and a cam before the end of the summer....and my question is...with heads and cam can i run the stock upper and lower intake??

yes....but why?? upgrade the intake.

I was just curious what the intake is capable of handling....i mean would it be way to restrictive?

Replace it for sure, definitly hold you back, and if its a money issue just wait to save up a little more, because if your going to have money forheads theres no reason not have some for at least a cheap street heat trickflow intake or find one used.

before you go and buy the cheapest one you can find make sure it fits your combo. or you could even go with a custom cam

Try looking at the Heads/Cam/Intake setup as a system... really should include, MAF, TB, EGR plate in the same breath, but any ways... the heads can only intake and exhaust as much volume as the MAF/TB/EGR/Intake will allow... regardless of cam lift and duration. At the minimum buy a used GT40 Upper/Lower. I'd wait a bit and get it all at once, but thats just me ...

ok so ill just get it all at once....but another question is....i may get a throttle body first but what size should i get if i am planning to get HCI.....and willthe larger throttle bodyhurt me until i do get HCI??

No,the larger TB will improve throttle response to a point. But yes you can go too big,Ideally you want the MAF to be slightly larger than the TB/EGR/Intake inlet, and you want the TB/EGR/Intake Inlet to be the same Diameter.

For Example: 73mm MAF with a 70mm TB/EGR/Intake Inlet, however a lot of aftermarket intakes are 75mm, so in that case you'd go with a 76mm (C&L Performance) these are highly tunable for different size injectors, so theres room to grow.

For a stock setup I'd go with 65mm TB/EGR... but if i were you I'd just wait and install it all at once
