My car will primarily be a street car, but I still want it to be really fast, obviously, so I'm going the stealthram route. I was wondering, though - I know nothing about heads and cams, so is there a set of heads and a cam that, when matched with the Stealthram, will still make good lower end power? It's pointless for me to have these awesome components if all my power is so high up I'll never get to it on the street (legally).

I'm not asking for magic parts, I'm just wondering if there is such a combo.

I've gotten the impression that putting on all these high-flowing parts will cause one to sacrifice all the lower end power, but if there's a combo that made for gains up top but could at least match stock down low, then I'd be happy with that.

Thanks guys.

Since this will be primarily a street car I wouldn't be too concerned about losing low end power. Unless you are running DRs on the street then you will easily have more power than traction.

jamesbob02

Thats good to hear. How will it compare to stock, down low? I'm quite happy with the torque I get right now, so as long as it's comparable, I'd be happy - especially when the power just keeps increasing from there!

I guess for an example, I see a lot of guys do a HSR/AFR/LT4HC combo - what would that be like on the low end? Just for an example, ya know. Thanks again.

For what you want to do, you may want to consider a SuperRam.

Thanks for the recommendation, but no way! I've pretty much been scared away from it, and it is expensive. Thanks, though.

My HSR combo is great on the street. It has lots of low end. Not as much grunt as the LTR, but still enough to plant you in the seat. The only thing I haven't done yet is spin the rears from a stop without power brakin...

i run the tpis zz-9 cam and springs along with the stealth ram and 113 vette heads and it will spin the rears all the way thru first and into second. i felt very little torque loss swithing from the LTR setup to the stealthram. im also running 373 posi in the rear.

jamesbob02

What gears are you running? I'd still like to be able to break the tires loose.

Right now I am running stock 3.42s. I am saving for many things, and rearend is on the list.

i run the zz4 cam with mine. have no loss of low end response for me. converted from slp runners (siamesed) and edelbrock base. click the green banner to see others.

ya i to lost almost no power.... none that i can feel.


in the space of 1 month i went from stock LTR/base.. too SLP/edelbrock base.. too HSR. all 3 with the lt4 hot cam

i have no problem spinning the rubber off. and all 3 set ups have what felt to be about the same TQ.

What scared you away from a SR? It may be a bit more of apain to get on, but otherwise nothing wrong with it. I am running LT4 hot Cam, AFR 195's, and a SR 1.6 rockers, etc... Nothing wrong with the super ram

I'm guessing the price. HSR = $500 SR = $1200

jamesbob02

Yeah, price and installation of HSR vs. SR made the decision way too easy.

I got my complete lingenfelter SR off of ebay for 800 shipped and that included the TB, AFPR, fuel rails, extrude honed base, the works... Plus new fuel lines and accesory holder - BRAND NEW

if your concerned about loss of torque go with a 383, HSR, LT4HC with AFR heads and headers. Perfect combo....YES?

jamesbob02

eventually I'll have a 383 with it - its on the list

Twelvz

stupid question...

what is HSR ???

92 zzz28

HSR= Holley Stealth Ram. It is basically a dual carb tunnel ram manifold that Holley modified to accept fuel injection. Works great and looks good too. Check out Thunder Racing for pics and prices...

With 383 you will not notice any torque loss, but the mid range punch will leave you grinnin', big time.

Hey RickTPI how do you like your raptor? I am trying to decide which of 500 different routes I want to go with my tranny. It's between having my tranny rebuilt by a local club member, a probuilt or a raptor. I just hate the fact that the cost DOESN'T include a TQ...

Ricktpi

It's holding up very well. Shifts firm at all rpms. Mine included a 2800 stall converter.

Keeping your low end response is all in the camshaft you choose. Shorter duration, wider lobe separation, and less overlap will keep your bottom end power. The most common mistake is too much duration. The second most common mistake is too much overlap. The third most common mistake is people trying to push the limits on how much duration they can get away with, and then not install a good stall converter. Then remember that for a street car the stall is acting as a bandaid fix for low-end response most of the time you're driving.
