heads and cam supporting mods?

**Professor Chaos** · 02-11-2009, 08:58 AM

I'd like to have Heads & Cam installed into my car this summer, and I'd like to know what else I should do to the car to support it. I want to keep it a daily driver during the summer, I have a truck for the winter. All I have done to the car right now is Edelbrock Shorty Headers and Corsa Exhaust. I've been looking around and this is kinda what i'm leaning towards right now.

It's the Performance Package 1 from Livernois Motorsports in Michigan.

i would say the next step for you is to get an intake and throttle body. id go with the fast 92/92. if price is a concern than at least an ls6 intake.

**blue02Z** · 02-11-2009, 04:02 PM

auto or manual??? if auto get a stall, you'll definately need it, need subframe connectors as well. get long tubes, ditch the shortys

**INMY01TA** · 02-12-2009, 07:30 AM

Ya I'd say long tube headers with the heads and cam. LS6 intake at least. If your an auto you will need a stall. If you're a manual I'm personally not a fan of going into the moter before adding a decent clutch and swapping out the rear for a 12 bolt/9 inch. Yes this stuff gets exspensive. Lol. I've heard great things about the Livernoise (sp?) heads btw.

**Professor Chaos** · 02-12-2009, 12:49 PM

Okay, so since my car is an automatic, I'll need a stall. Then the intake manifold and throttlebody.

How much can the stock bottom end handle? I thought it can handle somewhere around 500rwhp, would I really need to modify the bottom end? I'm only looking to get between 400rwhp and 450rwhp out of this.

plus 1 big time on long tubes vs shorties. you get alot more flow with LTs and that means more hp and tq across the board. those shorties flow almost the same as stock exhaust manifolds i hear. but definitely a different intake manifold. ls6 is a solid upgrade for our cars aswell as the fast 92mm combos but the fast is a bit pricey for my current situation so i went with the ls6. with the ls6 intake it is power across the whole power band not just peak numbers, which to me the curve is more important than peak numbers for my build at least. talk to the guys at the shop to get your range of power rpm wise and then you will be able to pick a stall converter from there. most common is 3000-3800 but it really depends on the set up you want. 3k is cool for bolt ons, while cam or head/cam combo would most likely be upper 3ks.

Honestly, you dont need heads to acheive 450hp. But you do need to upgrade your valve springs and keepers.

Im running 440 RWHP(dyno proven), with an Ls6 intake, Futral FM-14 cam, dual valve springs and titanium keepers and longtube headers with Borla adjustable exhaust.

Stock heads, MAF, and TB. Stock bottom end. Ls7 clutch and master cyl, 4.10 posi unit in stock rear axle.

ANd the plugs are NGK TR55's

Im gunna have to call BS on that one. There is no Cam that would net that kind of HP. lets see the dyno sheet. also what are you running in the 1/4? not trying to attack you or anything, i just dont think thats right

I agree. At least not on your average Mustang dyno. My car made 401hp on aMustang dyno with a healthy 230/236 cam with all the bolt ons. My tuner said the healthiest cam only car ever on there made 430ish. Maybe on a generous Dynojet but who cares, dyno #s don't mean anything.

Click my sig in the post above. ^^^

My buddy and I did all the listed mods, except headers and exhaust, but he/we bought it from a mechanic at Superior Chevrolet in KC. HE did the exhaust and some other things.

Car has only been on the strip once, and pulled a crap 12.4 on crap tires.

Heartland Park doesnt start up til March, So I have to wait til then for my numbers.

No BS implied.

**Jays00ss** · 02-12-2009, 08:46 PM

Almost the same set up here.

410 RWHP here with 4.30's and a 9" (6 speed) love my cam as a daily summer driver. 230/232 cam with ported 241's. Love my set up and is a perfect street/stip cam. Stil get 24 mpg on the street wheen i keep my foot out of it.

Look at my f quick for all my specs

**mark21742** · 02-13-2009, 12:28 AM

as far as bottom end, while your doing everything else on the top end, I'd go ahead and put in some ARP rod bolts.....do you need them, no, but its cheap insurance

**Willfully Armed** · 02-13-2009, 03:10 PM

Guys, I was wrong, and feel like a complete asshole

My memory has been slipping lately, and I dont know why.

I had MC Racing email me my dyno sheet. And boy was I way off.

Again, I feel like a complete tool.

Although my buddy and I swear there was another dyno pull that netted more than this one, we both feel this was the pull before the tune. But I will stick to these numbers until I can find the other sheet.

You definetly need to get rid of the Edelbrocks and get LT's. That will be your biggest improvment over intake and stall!

what type of LT headers do you recommend? price doesn't matter.
