I have some agreements, and disagreements with your post.
I do agree about the rockers bring crap. I suggest getting the FRPP 1.6 rr's, they are a good set.
Now for my disagreements.
Yes the Holley SystemMax kit is a good kit, but price went up a little bit, due to the newer heads I think...ask
Rick91GT.
However, that claim for 350 fwhp is bogus. Don't get me wrong, the Intake is the best on the market,
BUT the heads are no better than the GT-40's from the tests and articles I have seen. They flow about 230 cfm@.550. I think the new ones that just came out or are coming out flow around 240.
The cam is a piece too. It's lift isn't even in the heads peak. I think it lifts around .509, but the duration is in the 270's. In order to make 350 fwhp, you will need atleast 290 to the wheels, and those heads and cam won't do it. I had my car dynotuned with my combo below without my blower, and my best was 286. The TFS Intake isn't quite as good as the Holley (245 cfm vs. 260) About 5 hp less from AFM. TFS heads blow the Holleys away (257 @.500 vs. 234 @.600) and my cam is a better cam (.542/.563 vs. .509/.509) You can piece my kit together, but you wouldn't be able to get the #2 cam w/o flycutting. For the TFS SH Intake, TFS TW Heads, and the TFS #1 cam which is more like the F303 cam (.499/.510, good duration numbers though)
Here are some comparisons, and my opinion(which isn't always the best
)
HOLLEY
Intake: $600-700 Flow- 257 cfm
Heads: $1100-1200 Flow- 234@.600 I
188@.600 E
Valve Sizes: 1.94/1.60
Cam: $200 Lift- .509/.509
Dur.- 276/280
TRICK FLOW
Intake: $400 Flow- 245 Street Heat
$450 Flow- 255 Track Heat
Heads: $950-1000 Flow- 257@.500 I
196@.500 E
Valve Sizes: 2.02/1.90
Cam: $140 Lift- .499/.510 #1
Dur.- 275/279
$150 Lift- .542/.563 #2
Dur.- 286/294
Holley as far as I know doesn't have the wide variety of products like TFS, making their kit a as is kind of set up, not a Holley mix and match. Although, you could get the Holley Intake, heads, and a better cam and you may be able to get 280-285 rwhp.
My buddy has the SystemMax kit. He ran a 13.3@106. Dynoed 274 rwhp. That IS NOT 350 fwhp.
Here IMO is what I think your best bet is:
TFS Heads: $1000
TFS Intake: $400-450
TFS Cam: $140-150
Rockers: $180
Rods: $100
Fuel Pump: $100
FPR: $100
Injectors: $200
Gaskets: $120
TOTAL $2400
That is extremely cheap compared to the SystemMax kit that is now about $2200. Then you have to get the rockers, fuel pump, FPR, injectors, and gaskets. That comes out to about
$2720.
Another thing to think about. You won't make 290-300 rwhp with any of these combos without a good TB and MAM. That would run you another $500. If your conversion is the Cobra....get rid of it.
Also, there is no way that your stang will run with your SS, running 116 traps. The best you could do with your combo will be around 107-108 in a full weight car. Don't read those claims in Excessive Motorsports ads.
I am not trying to start a flame, I am just sick of Holley getting praised for their heads, and cams. I just know my friend was extremely disappionted.
GOOD LUCK
