No, it will have more overlap than stock.

overlap is when both the exhasut valve and the intake valve are open at the same time right? i want more of that?

Yep. That helps give the car that "lopey" sound. At higher RPM it helps get the exhaust out and intake in faster. You suffer at idle though. To pass emissions you will need a cat.

Change cams/heads you WILL need computer work.

I also think that a good set of Vortec heads will be a good investment. I say this because I'm thinking about what shultzy hinted at. Think about the big picture with the car. Yes, you do have an immediate problem that will get worse if something isn't done. If you're gonna have to spend the money to fix or replace it, do what you want to the first time. It might be a little extra dough, but its money well spent. Find out if it really is valve seals or if you have another problem going on. Make a plan and then set a (realistic) budget, and go for it. If you end up having to remove the heads, you can make money towards the new ones by re-selling them. besides, even if they aren't at optimum flow (for instance, just doing the heads and sticking with the stock TPI) it'll still be an improvement, and there will probably be some (maybe small) power gains that come from it. just my .02

It's not cheap but let's be accurate. The manifold is $895 and if you purchase their fuel rail kit that runs $355.

-Schultzy

Excess of $1200 would equate to $1250 lol


Well I took the 'intake alone' to mean the intake manifold. Whatever, of course you are right.

We are still all over the place here but I gave my 2 cents. Next thing you know we will have Tony in an awesome set of heads with a big 'ol cam and a stock TPI base/runners. Weeeeeeeeeeee.

well, if i go with vortec heads i would need a new base in order to keep my TPI. thats why i am looking at alternative intakes. that TPI base is 300+ allready. might as well spend the extra dough to get a better intake.

carb Shocked Laughing
i like my fuel injection thanks. i can mod the shizzle out of it and remain emissions legal. also i am scared of carbs. one of my mopar buddies was telling me how lucky i am to be injected "my carb has over 100 phisical settings i can screw up"- i think he was exagerating, but still...

i know mike has TPIS miniram, and paul has Holley Stealth Ram. do they both move the power band alot higher? i like low end tourqe. alot. (by that i mean both "i love alot of low and tourque", and "i love low end tourque alot") Very Happy

hmm.. carb.. should i ?

Then leave it where it is. Or get bigger cubic inches. That's pretty much all you've got going for you in that range. Sure there are a few things you can do, but nothing worth the money.

You've got to spin a small block to get the air flow to make the power.

Mike and I shift around 6k.

If you really want the torque then stay TPI and spend twice, if not three times as much making it flow less. Smile

Fuel injection is cool, but I guess to me there's more sensors and relays and more electrical to fail or go wrong on me or be run incorrectly. That's why I prefer the almighty carburator. To me a carb is simple, and simple is good.

More lowend torque..........put shorter legs under it. You'll get all kinds of torque.......4:10's........would be a tire smoker. Probably the cheapest way to go. Will need to have the speed sensor programed so the digital speedo reads correctly......at least that's what I was told.

If john gets to involved he will have a awesome set of heads cam intake sitting in his living room floor, for a year, just waiting to get those last few gaskets and other parts so he can do it all at one time.

NO no no. He will have everything he needs, plus a spare set of wheels, plus parts for his other car. Then he will descide it is too cold to work on the car.
