Motor will be iron L98 heads, mildly ported, to what extent i have no idea wont find out until i tear into the top end, know it was professionally done two owners ago.
Going to get some head work done to get as much lift as possible out of the heads hopefully can go with 1.6 rr with the cam i want.

cam will be something similar to comp cams XR276HR, 224/230 duration, .503/.510 lift, 112 lsa

So its either stock Stealth Ram, or ported lt1 intake that still needs to be converted. I've never seen a stock lt1 intake so no idea how far this is ported, and it comes with everything included in the pic, injectors and bbk throttle body.

Which is the better choice for my combo?

 

come on, no one with the expertise to know whats going to work? I know i can get a nice flat power curve all the way to my peak rpm out of the hsr, but have no clue what a ported lt1 can do

 

The LT1 intake is designed exceptionally well. Well enough that no one ever made an aftermarket intake to replace it(although Edelbrock currently has one in the works to replace the now discontinued LT4 intake). I have no knowledge of the stealth ram, but compaired to the stock TPI intake, it will loose a bit of low end, but pick up tons on the top. People are running ported LT1s into te 500HP range, over that something better is needed.

I was able to find this if it helps you decide at all:

lol i think i really am looking for someone to convince me i should be using the lt1, largely cause its a bit cheaper and comes with a wicked looking TB.

I'm starting to get the feeling tho that with l98 heads, even ported, rpm wise im going to be limited so the broad torque curve of the hsr is going to make a hell of a lot more power, even with a stock tb.

You gotta remember im not going to have a 500 hp motor, my goal is 350hp/400tq at the engine and im expecting to fall slightly shy of that, if i surpass it ill be extatic.

Oh the exhaust is also slp headers into mandrel bent 3" y pipe

 

If your heads will only support 350 -375 horses, it will depend on your gears and stall speed whether or not the StealthRam would run any quicker than a ported stock base and ported SLP runners - assuming traction.

 

gotta read the thread better

Its stealth ram vs ported lt1

And i guess i should mention theres already a tko-600 5 speed in the car, gotta update my profile

 

At those HP levels, I doubt you'd see much of a difference one way or the other. Maybe 15-20 HP. If the LT1 is cheaper, run it. If you don't like it, you can sell it later. Personally I love my LT1 intake(course it's on top of an LT1, so i'm probably biased )

 

im not worried about 10 hp, im worried about 50 ft lbs which is my scare, if the lt1 wont give me the mid range i need for a low hp motor

 

I was trying to save you a few bucks if you still had the TPI, but if it's one or the other - StealthRam.

FYI for Coach, Lingenfelter made a SuperRam replacement for the LT1 and the swap was worth a few tenths on a stock LT1 - based on an old rag I have. It's just there were better things that you spend that $1300 on to get bigger reductions in ETs.

 

It's been ported, how much I couldn't tell you, but that should make up for something. Professionally done mind you. I was going to build a 320-350rwhp motor and was told this would be more than enough for what I needed, how would that hurt him enough to notice a difference? I say loosing power at certain low rpm and gaining it back in higher rpm with better numbers is an even trade. I'd be more worried about the heads/cam combo than the intake.

 

I'd go with the LT1 intake. It's cheaper and will support massive amounts of power. There's a reason that no one gets an aftermarket intake for a Gen 2. The next step up from ported stock is simply a custom sheetmetal intake.
