i need your guys input

[EatM up]

should i run a intake gasket that has a valley pan or not? ir what should i do for intake gaskets sense comp cams talked me into getting a bigger cam and it does me no good now i have to get a new one again so im looking into roller rockers now and my motor is pretty much built bersides some billet main caps and a gurdle how much guesstamate power should this combo make or should i just sell it all and go for a 86/86 setup?

thanks josh

How fast do you want to go? What exactly is your setup? How big is your budget? Bigger cams are really a waste of money unless you are really pushing the limits of the stock housing turbos-if then. Brad

Intake Gasket

Do yourself a favor and stick with the stock style intake gasket unless you want to deal with all types of crankcase ventilation problems.

 

[WFO]

What cam do you have and why do you need to get a new one and roller rockers?

Fel pro blue stock replacement valley pan is good.

Do you have ported heads and intake?

 

[EatM up]

I allready gasket matched the heads and intake with a felpro race series gasket i forgot the number at the moment as for the camshaft i got a 69-000-5 custom grind cam at that its 224/224 50 .493 lift flat tapper
and i got the fordge pistons headers dp i/c front mount alky etc. stock rods and crank i would like to make around 600hp my limit was set at $2000 for the motor but im allready way past it and so money isnt a issue

You have a IC hotair engine or a IC 86/87 Engine?

That's not that big of a cam,who told you you need roller rockers?

I know Lee always runs "big" cams maybe he'll chime in.

The numbers look big for a turbo cam,but a 224 cam is run of the mill performance grind.Just make sure your valvesprings are good for the lift.

I kind of disagree with you on this one to a point. It's not that big of a cam unless you have a really big turbo and proper stall speed to support it. A cam that size will move the power band wayyyy up the RPM chain and if you don't have the other supporting factors your car's gonna be a dog until it hits about 4000 rpm. And by then if you have a small turbo it will be on it's way out. That's why it's the combo that makes the difference not just big, big, big on everything.

its a hot air car with a ic that i got from wfo

Well he says he has a built shortblock and a 600hp goal so I doubt he plans to run the stock turbo and a D5..

There are plenty of other factors that play into cam design that will determine how it will run and idle. It wasn't that long ago that everyone was regurgitating the "stock cam is good for 10s blah blah" line. This may be "true",but if you hang the valves open farther and longer you'll make more power all else being equal.Saying you won't is ignorant.

It'll all come down to if the cam retains driveability at the desired power level.

 

[WFO]

Don't misunderstand me here...I'm not saying a 224 is the best cam ever for a street car.

But if you can post the cam card we'd be able to better judge if it's going to be suitable for your application.

You also need to know NOW what turbo and convertor you're going to run and what your actual goals are.Otherwise you should just go small and hope for the best.

 

[WFO]

For reference only...

In 2003 Lee Thompson, Dwayne Thompson and Scott Porter were all running 218/224 cams and going 10s...

Cam

But he said flat tappet and that's wayyyyy different than a roller set up. With a roller it would not be that big of a deal do to the design of a roller itself to run with less drag. But on a flat tappet big duration cam. Idle quality and delayed power will be an issue without a bigggg turbo (60XXX plus series) and a good 3000-3200 stall converter. It will make power but you might just be crossing the finish line when comes up on it's peak powerband without the supporting mods.

 

[EatM up]

ok so what should i do i will list everything and what should i change for my 600hp goal

felpro race gasket matched heads and intake
ported tb
bigger turbo dont know what yet because of im moving the TB away from the turbo
headers
3"dp can
bored .40 over with forged pistons
3" exhaust
alky
60# injectors
front mount sperco intercooler kit
that cam that i dont know
have no idea for tranny but am open for ideas thanks!
stainless steel power flo valves:wink: (just like the stage 1 i believe or 2 valves)

i dont know to much about these cars but i would like a 600hp beast and this is my 1st buick so i have some high hopes

Wowyeah sure wouldn't want to have to run monster 60 turbo and a huge 3200 stall. Did I mention ...

Fvck it...run a stock cam and a stock turbo.

 

[Boost231]

as for a tranny, look into lonnie diers at Extreme Automatics Where winning is easy as he has some good deals going on. there are other on this board that build killer tranny's as well you will just have to search on who is closest to you.

 

[WFO]

And if you had bothered to read more than the title of the thread I posted...those 218-224 cams are flat tappet.

But what do those guys know,with their big scary turbos and stall converters and 10 second time slips...

 

[Boost231]

they know nothing as well as you LMFAO.

Going to subscribe

Watching with interest... I have a small 206/206 cam. :biggrin:

Ok you got me, I didn't read the link. But you know as well as I do that Leo ran a hybrid turbo equivalent to a "I think a 63 series" in an 87 housing on that car with a 3000 plus vigilante multi-disc lock-up. And that is a hell of a difference than running a big duration cam, TA33 and 2800 stall converter. I'm not disputing you, I subscribe to the same theory that a cam is too big when it can't fit in the block. But what good is a huge cam without the supporting mods to go with it? The only goal you will accomplish is leaving useful horsepower on the table because your engine can't make sufficient power up to the powerband that the cam is designed for. And you WFO should know that I'm right. I have not said one time that the cam he chose was too big, all I have said all along is that he needed the supporting mods to go with it. So why all the chatter? As a kid before I was into racing I remeber seeing highschool buddies with small block chevy V8's with the lumpity, lump cam and that thing sounded killer but was a dog out the hole and would barely spin the tires.......I'd say he was mismatched. After learning more about cams and the affect they have on the power band I choose to go with the theory that bigger is not always better if that's all you got is a cam.

EatM up.......everything you listed in your combo is fine even the cam but that's pending on your turbo and converter choice......maybe tech specialist WFO can help you out with that.:biggrin:
