02 camaro with tsp ported 241 heads and mild cam pkg w/LS6 intake, with LT's 402/394@ the wheels on mustang dyno with 3.73 gears. DD/Road race.

Looking to bump up the power 60-75 hp with good throttle response and good tq through out maxing at 6400-6600 rpm. Which heads, cam and intake can get me where I want to go?

Maybe just throw a much more aggressive cam in there and dyno on a Dynojet. (adjust tune of course) See what happens.

If you want upper 400s on the stock cubes you're most likely gonna have to get some CNCed aftermarket casting heads with a cam to match and a FAST90 or thereabouts.

I doubt just a bigger cam swap will get you 60+ at the wheels, and you don't want to put in a cam with the current heads and figure out that you don't make the power you want at which point you're going to have to do it all over again and get a new cam.

Though you might be able to get away with a very good set of ported 243s, but best bet is some TFS/AFR 215s or so.

475rwhp is often achieved by those that shoot for 500rwhp and fall short. You might want to read through this thread, especially the recent stuff, to get an idea of what it takes.

What are the cam specs? Can you be more specific about your set up? What kind of headers, whats the exhaust like?

AFR 205s, Custom grind cam, Mamo Ported FAST, 1 3/4" headers, and matching intake parts, will probably get you damn close with torque all over the place.

The engine that is in my car now made 470rwhp with basically the mods listed, the AFR 224/228 cam, in a 6 speed 'Hawk.

^This & this. IMO, under the curve torque is more important than peak HP on most road courses. So, gobs of torque w/ your requested peak HP is the goal. There are sponsors on here like Pat G that can get grind a cam for you. The cam w/ the other engine airflow mods, will get you there. Good-luck

I have not been able to find the cam card but it was something along 228/230 .580 114. Very good street manners and good with the heads for 70+ hp over stock, but I need at least another 60hp at the wheels.

I read the recipie for 500rwhp. I moved to slow on some afr 205's, so I'm back at Trying to find a pkg that will give me what I'd like without doing a stroker kit.

I got a chuckle out of the suggestion to use a more generous dyno and use my current combo. That's a good one. Not.

Putting out a couple grand and only gain 30hp would be diss appointing, that's why I'm throwing it out there. And I have some cheapo pacesetters and 3" exhaust that does need worked over.

What kind of budget do you have? H/C/I and exhaust to hit the power you want is going to cost more than a couple grand.

Good. Then you got the spirit of my comment. Just for Car buddy humor. The closer you come to the 500whp mark, the more expensive each horsepower is going to be than the one before it. Budget wise, there is a point of diminishing returns. Above 450whp. (dynojet) just plan on spending everything you have. Because to get more power than you have, you have to have better heads. But for those heads to flow, you need a strong cam with all supporting valve train mods. (big $$$) but for those heads / valve train / cam to flow, you need An intake and throttle to keep pace. Larger and better exhaust. Don't forget about the extra fuel you need. Fuel pump and injectors good enough? Tuning?

etc. etc. etc. So.. the true answer(S) to your question gets very involved. No one simple answer and you're not going to find it here in a quick answer. This is mostly why you got directed to the 500whp thread. Aim for that and you might get 475whp. It's truly all I'm hoping for myself. In my road race car. It is not my daily driver. So you are asking for a lot. - not a mean tone.

Have you considered turbo or procharging it? You can make 500rwhp on 93 oct safely but Idk how it'd pan out on a road course. But once you start looking at the best heads/intake etc. for a LS1 then you're not far off the cost of getting there with boost.

I know it's found in the combo, and one that is done right. I found it indeed interesting in the recipe post a diff of 496hp to 440hp from one dyno to the other, and if that was the basis of the comment it was not lost on me.

That was my comment in regards to a few thousand only showing another 30hp. It seems altogether possible to spend $5000 to pick up 40hp which may indeed be a case of diminishing returns?

Having had a 67 camaro setup for rr with a 700hp bbc I fear I may never be quite satisfied unless I take the 69 I have and build a 650hp ls3 track car over the next year and call it good at this point with the better brakes and sway bars added to the current version of the 02 and be satisfied to run in the top 3 of the intermediate group while working on something to go run with the big boys in the advanced group as I did previously.

Decisions, decisions.

So, if you still have the '67 why not just use that? Why switch to the LS3 when you already have all that power in the bbc? Is the '67 what let you run with the big boys? and why did it stop? What 02?

Pacesetters arent too terrible. My friend's 'Hawk dyno'd 448/434 with AFR 205s, 224/228 cam with an SLP Lid, stock maf (SD Tuned, but maf was in place) Stock unported TB, LS6 intake, Pacesetters, and TDs.

Shoot Tony Mamo @ AFR a pm, he'll be able to help you reach your power goals.

Unfortunately my prior 67, 68 and 69 were all casualties of the economy and a lost house and biz. I tried to buy the 67 back but it ended up in Australia. With the bbc there was only one car faster down the straights, but it pushed hard in the corners, hard on brakes and cooling and with the potent LS motors getting close in power and another 150+ off the nose makes all kind of diff in a rr car.

The current 69 was a "deal" picked up on eBay and it does something for me the 02 just doesn't. Only problem is with it is it would take $20,000 to get it to where the 02 currently is, running in the intermediate group, and I'd like to get back to dueling with the big guns. $5000 is my budget.

That's my sad story. Similar to many out there. But...I'm trying to make a comeback and at least have 1 fast car before I get too old to do it anymore. At 56 it's kinda a now or never thing for me.

Original post states "ported 241's." Ported 205's & a better cam can get you there. Especially, if you're using a carb. The carb style intake does not have the same limitations above .600" lift that the EFI intake does.

Badmeat

iTrader: (1)

I would think that a cam with those specs would have very good throttle response as well

LS6 intake on my current 02 car.

The 69 (which is sitting) has a 383 sbc in it that needs some tweaking to run halfway decent, along with $10,000 in brake and suspension upgrades, not to mention another 10 grand in wiring, interior/exterior finish and another $20,000 for a good engine, trans swap. Ouch.

And I believe the cam specs in the 02 may only have a .550 in there.

OK, still can get there w/ ported 205's & specific cam. Really don't know why your 205's felt slow. They are proven heads. Can also open the throat on the LS6 intake & use an 85mm TB & MAF. I have a thread in here on how to do it @ home.

Possible scenarios

Budget:
-home port 205's, $30 in dremmel parts
-home flycut pistons, $45 tool
-dual springs, may already have? (#8019)
-hollow stem intake valves, $400 have no clue as to the cost
-open LS6 intake inlet, $4 high temp silicon for gasket
-port match intake to runners, free
-used 85mm TB, $100 ish
-used 85mm MAF $45
-spec'd cam grind $350
-.030" head gaskets to increase CR, Cometic $180?
-.105" comp hardened pushrods, $180?
-degree cam, (a$$ume you have the tools)
-head bolts, stock $50?
-new dyno tune $500
Power through 7200 RPM


Other option is the carb w/ ported 205's carb style intake w/ specific cam.

Budget:
-home port 205's dremmel parts, $30
-dual springs, may already have? (#8019)
-hollow stem intake valves, $300? I have no idea what they cost
-.030" Cometic head gaskets to increase CR, $180?
-home flycut pistons, $45 for tool
-port match runners, free
-used carb & intake $800?
-spec'd grind cam. $350
-degree cam, free
-head bolts, stock $50?
-.105 comp hardened pushrods, $150?
-new dyno tune $500
Power through 7200 RPM


In each example, could also add decking cost for 205's in order to increase CR even more.

You'd be better off going with more cubes so you can get the HP/TQ numbers without having to spin the motor to the moon. Spinning these motors to the moon on a road course doesn't tend to go too well...any oiling issues will be quickly revealed. Most of the seasoned guys that have been around road courses for a while will be the first to tell you that revving to the moon is usually not the quickest way around either, and it's hard on parts.

If you really need the power, build the bottom end first, and pay close attention to your oiling system.
