I want to build a bad *** 350 and drop it in my car and i'm starting with a bare block. I saw the mini-ram on www.tpis.com and the fuel rail that goes with it and wanted to know how sick it was. it sounds like it freakin rocks! does anyone have any experience with this setup? i'd love to know cuz the whole setup is like $1200 and i dont wanna drop that much if i can get the same results or close to it just by porting the stock intake components i already have.

miniram is wellll known. search for it. VERY expensive i dont think i'd spend that money unless i got the 1206 ported version, and AFR 210-220 heads and was building a very hot 383-400+ inch motor that wanted to rev over 6500 rpms
stock TPI stuff wont come close, ported or siamesed. Only thing cheaper is a converted LT1 manifold and Holley Stealth ram. LT1 is pretty much the same as the Miniram, and the HSR is only alittle off on performance. 550 dollar HSR vs 1200 dollar miniram for most builds, i'll take the HSR any day of the week

ok i looked up the holley stealth ram.... System Includes: Upper and lower intake manifolds
58mm billet throttle body
Bright clear anodized aluminum fuel rails
Fuel injectors
Fuel pressure regulator
255 LPH fuel pump and fuel filters
Commander 950TM ECU
All wiring harnesses
Software and communications cable
TPS, MAP, coolant, air temperature and oxygen sensors
Detailed installation and tuning manuals
this setup is $2387.99!!!!!! i see that u get the 24# injectors fuel pump and filter 58mm throttle body wiring harness and software, but thats a difference of $1100!!!! is that difference about the same price i would pay for the mini-ram and get those things seperate? plus, what are the power gain specs on it? the mini-ram says from 75 - 125 hp gains depending on engine mods! what about the HSR?
hey i looked and didnt see anything like that for $500. i saw the holley stealth rams but they were all like $3000 too! do u have a part number for what u r talking about?
With the HSR it's an intake. You will also need the fuel rail kit cause it's specifically for that intake. If you have fuel injection, you use your ECU, wiring, injectors and sensors. If you don't have EFI then you need to buy the expensive kit with the wiring, ECU, injectors and sensors. Keep in mind you will need a good tune to benefit the intake and to also lose the EGR system. And if your car uses the 9th injector, you'll need a bin from a 89. I'd stay clear of the 58mm TB if you're gonna be under 400ci. 52mm is perfect. 22-24lb injectors will work as well.
I installed the Miniram on my car before the HSR was introduced. With just the intake and 52mm TB, I dropped almost a full second off my ET! The HSR is a close setup so expect at least 3/4 of a second. Crazy huh?

Well as u may have noticed I dint really know alot about cars. But I just recently read a thread on here that was talking about a vortec intake with vortec heads. Is this possible and if so would this go along with the hsr intake system. Thanks again

There are a few intake manifolds that will work with Vortec heads.
Holley Stealth Ram
GM Ram Jet 350
Vortec TPI
I'm running a Vortec TPI manifold in my vehicle now. If you don't know what to look for (bolt pattern and location), you would never know. The Vortec TPI intake is simply the lower portion that bolts to the heads. The intake ports on the Vortec heads extend higher/taller than early heads. All TPI runners will bolt to the Vortec TPI intake. And since the runners do, all TPI plenums can be used with the Vortec TPI intake.
Vortec TPI is a nice intake manifold, but still runs out of air in the upper RPMs. I used to run the Ram Jet 350 intake manifold (below). A better choice for all around peformance when compared to the Vortec TPI system.

so since i dont know how to build engines this is the setup that i am gonna try to get. Please let me know if this will work or if this is all i need to make this work. i am gonna get the Wieland vortec intake manifold from summit prt #7542, then the GM perfomance vortec cylnder heads prt #12558060, then the holley efi fuel rails prt# 534-186.
please let me know if i am missing something to make this work or if the vortec setup is really worth it or if there is something better and cheaper out there. since i dont really know alot besides just doin maintenence on my car amy help will be appreaciated.

On the TPIS wesite the example of a built 350 using a 52mm TB and their ZZ-9 roller cam with the Mini Ram produces 450 HP and 430 Ft/LB. I to am considering this intake since I already have their TB and cam. I chose to go with Trick Flow's 195's instead of the AFR's and put them on a ZZ4 short block. Are you of the opinion I will be disappointed if I opot for the Mini Ram?

Bear in mind the MR is a top end intake that likes heads and cam to perform at it's best which then need gears and stall changes.You appear to have the lot to make good combo.
I still would not overlook the cheaper HSR.
Comes a very close 2nd especially for street use especially the bottom end performance
Will WND-7540 work with my 91 Z? It shows up to 1986
I believe they come with the center 2 intake bolts holes elongated to fit both head bolt angles; if not you can just file them out to suit your later heads with the 72 degrees angle
