...my wife says so!! I'm looking for ideas on how to spend it based on my sig below. Now, keep in mind, this is probably the last time I'll ever have this kind of money, so I can't mod based on future mods. I have to base everything on what I can get NOW. Understand? Ok, I'm going to throw my ideas out there for comments, so fire away with your thoughts. My thoughts...

Plan A:
Edelbrock TES headers with JET HOT
Edelbrock TPI base
Holley AFPR

Plan B:
SLP 1 3/4" uncoated headers
Edelbrock TPI base
Holley AFPR

Plan C:
Edelbrock TPI base
AS&M Runners
Holley AFPR

Plan D:
S/R Torquer heads
$200 Camshaft

Which of these setups will net me the most power? Keep in mind I don't have headers. If you don't agree with the above, what would you change? Feel free to suggest new setups as I could be missing something. Thank you all for your time. I really appreciate it and please hurry...I'm excited!

Go with a or b. I don't think you will get the best of power out of C with out headers.

1. Dremel and porting bits $100. Port your base plate, plenum and touch up the heads. Follow this www.sa-motorsports.com/diyport.htm

2. SLP 1 3/4" Headers $430 at summit after 10% off

3. Comp Cams Xtreme Energy 218/224 112 ls camshaft and springs $350 plus gaskets, lube etc

4. Subframe connectors.

5. Time and patience

This is about all I was going to do with my old motor before I decided to go crazy in my quest for speed.

I agree with Mark, go with A or B, those are your best bet! Just a suggestion, you could consider getting a set of Trick Flow heads, they are a little less than a $1000, maybe enough would be left to buy that Holley AFPR.

I would have to disagree with you guys, if I had 1000 to spend on a somewhat stock car, I would go with D. Headers and intake manifold are not that big of a deal, I think heads and cam would be the most fun to change of all of those things. If you're only going to get to do it once, I would do heads and cam. You can always port your intake later, supplies are cheap. AFPRs are cheap too. Headers..well heads/cam would be more beneficial. Just my opinion.

Fred91TA

I'm leaning toward this. What would the following do for my horsepower and torque? I plan to set the AFPR around 50 psi. Is this cool for stock injectors? With the 10% at Summit, I don't think I could be anymore efficient and effective at spending the grand. Anyway...

Edelbrock base (EDL-3860) 320.00
JET AFPR (JET-61501) 72.00
TPIS TPI Gasket Set (shipped) 25.00?
SLP Headers (SUM-SLP30002) 432.00
SLP install kit (SUM-SLP30024) 58.00
MSD Plug Wires (MSD-31229) 60.00
Stage 8 Bolts (STG-8911) 29.00
Handling (Summit) 7.00
Total $1,003.00

Thanks again for past and present input.

Sorry about all the posts, but I'm also going to port my plenum when I'm doing all this. Can I get a rear wheel hp estimate for all the above mods, this mod, and my sig mod? Thanks...

I think that the porting and the base is good, but you still will only flow as much as your stock heads allow. You could always port your stock intake and spend that 300 bucks on a cam and some roller tipped rockers or something.

Will your wife be okay with that extra 3 bucks?

why not Nitrous????

under 600$ last time I looked in jegs for the TPI kit and thats a 150 shot!!

My advice would be headers and camshaft. Those are the first 2 choke points on these cars, so in order to get the biggest bang for the buck, I'd start there. If you have any money left over (as you should) I'd suggest rear suspension mods, like LCA lowering brackets ($60-$75 plus installation) and LCAs ($100 up).

I agree on the headers and cam. If the car is parked for the winter, this is a perfect time to do some porting on the base manifold. Port the plenum also. If you feel comfortable with porting, touch the heads also. With TPI, the air/fuel mixture is only introduced at the very begining of the head port. B/c of the fuel psi, it will be easier to polish the intake tract, and the exhaust, and not have to worry so much about turbulence. Pocket porting would help too. Just an idea.

$1000 is enough to do a complete switch to carb. The WILL BE THE BEST THING TO DO, NO IFS ANDS OR BUTTS.

Fred91TA

All excellent points being made. I'm really starting to buy into the cam idea instead of the intake. Now, someone suggest a cam for a stock long block. I want one that's pretty hot, but I don't like a lope. This is my daily driver even in what little winter North Texas has. Thanks...

Definately go with headers and cam. But don't forget to add money in for a timing chain.

I can get a 3 angle valve job done locally for $60. Since I don't have the testicular fortitude to touch it myself, will this help a good cam flow pretty good?

iroc5speed

get the three angle job done, port the plenium and baseplate, and get a new cam. then you will have enough money to buy some SLP headers. To me, this is the best option.

HEADSHEADS, cam, cheap headers, and something to make the computer like it(custom chip/good friends with chip burners) It might be a little over $1000 with all the little things gaskets, timing chain, etc. Some sort of headers is a given. HEADS and cam will make the biggest difference after that. Don't let these guys talk you into wasting you money on intake pieces. Spend $1200 and be done running 13s. Ask some people how much the paid and how much they gained in ET/MPH. I gained .9 sec and 6mph for ~$500(headers/chip/cheap stuff) and plan to gain another .5sec and 5mph with the next $700.

I'm with "beast" on this one. Heads and cam change and add a cheap set of headers.

Fred91TA

Would a ZZ4 cam or an LT4 Hot Cam work on stock L98 heads either aluminum or iron?

How about a set of aluminum L98 heads with a ZZ4 or Hot Cam with a set of Edelbrock TES? Would this kick my *** down the road pretty good?

Beast5spdGTA

the LT4 hot cam is probably too much cam for the TPI induction(doesn't create the right powerband to go with the TPI)Hot cam probably wants to make power in the 5500+ range while the TPI stock or not, is only good for ~5200rpms for peak HP, most likely peak hp will be lower than that as well. Just saying in general TPIs aren't going to make usable power above ~5400rpms so look for a cam with a max operating range below 5500. That cam was designed to go into a short runner intake like the mini-ram/LT1 style. It sounds like that $1000 to spend is burning a hole in your pocket, if so, I'd say force yourself to read and learn for at least 2 more weeks before you decide on what to spend it on.
