I have been reading on the tsp 233/239. I like what i see with curves. If i was to go with this cam what set of heads should i go with? The tsp ls6 heads or the stage 2.5 5.3's. What kind of difference would u expect comparing the heads to each cam. My car is a DD also. Check the sig for my other mods. that will also help with determining the heads to choose.

i would also like to know what u think bout the cam in general with my setup shown in the sig. will also be runnin ls6 intake with whatever i decide to go with.

get the ls6's for future upgrades, like a 408.

id also think about the patriot 59cc ls6 heads. supposedly these heads have the same piston to valve clearance as the stock heads so you can run the 59cc version with a .040 cometic for better quench and compression. You can also run bigger valves. The TSP ls6 heads are 64cc and if you mill them down and run a .040 cometic you'll run into piston to valve clearance problems with the 233/239 cam. Im looking into a pair of patriots for myself, im still doing research on the best heads for under 1500.

^Exact setup I have.

hey ls1kid, what are your hp/tq numbers and whats your compression ratio? A well regarded gearhead here said not to go over 11.2-1 here in vegas if you want to run pump gas.

0utLawTransAm

get the ls6 heads youll get more hp

My comp ratio is 11.5:1 and I'm fine on 93 octane pump gas.

The previous owner of the car told me it made 468rwhp. Not sure on the exact tq.

Since then I've put a ported FAST 90/NW 90 TB on it and larger fuel injectors because my stockers were pulling 25% duty at idle. I've also put on Harland Sharp roller rockers too.

So I have no idea what it makes now. I need to get it dynoed soon.

I agree with the 11.2 "ish" for max in hot temps.

I voted 5.3 heads. only cause they give a broader torque curve, and work best with stock cubic inch's (according to TSP) due to the ports. the LS6 heads are better for more cubic inch's and more wild cams. I still say 5.3 though since you said daily driver.
I just put a car together similar to this. it was 6sp, LS6 intake, 5.3 2.5 heads, TV2 cam and he made 429RWHP on a mustang dyno. your cam should yield slightly better peak #s.

nice numbers ls1kid. ill be going with a ported 90/90 set-up also but not until later.

TheLS1Kid

iTrader: (12)

Thanks, yes the ported 90/90 was a good investment.

It made the car sounds MUCH more healthy also. That old LS6 must have been choking it up.

There are better cylinder head options than the "LS1TECH coveted PRC heads." Please do your research and call the big name cylinder head producers like Patriot, Dart, ET Performance, and Air Flow Research. I do realize some of those makers are probably not going to fit your budget, but it is still good to talk to the experts to figure out what cc combustion chamber (and subsequently compression ratio) will be good for your application. Good luck.

he's right..alot of people also forget about TEA, look at all the people running fast times with those heads and small to midsized cams

yeah, its just a matter of money though. same reason why I ported my own heads. if I can get a big chunk of the performance that Id get from an aftermarket head w/o spending any money, then cool. for alot of people, same goes for the CNC'd stock castings. get most of the performance w/o spending $2K+ for heads. but, it would be very nice to have the best. I put AFR and ETP up there at the top of the heap.

How much h/p with a 233/239 and full exaust (no cats, wide open muffler(loud mouth 1)), lid, free mods will yeild?

TheLS1Kid

iTrader: (12)

Dragkid1917, It would probably put you around 400rwhp since your setup will still have stock heads.

I ran that cam for awhile..I went 12.4 @ 115 through a 12 bolt.
The heads were similar to TSP 5.3's in terms of flow..Maybe a little better on the exhaust side..Just make sure you get them milled to 61 cc & a .040 Cometic gasket to keep the SCR up...
I made 427/385 with a 62 cc head & it wouldve done better with a little more compression.

If your worried about PTV clearance you can always request that they sink your valves seats deeper in your heads when you order them.

Irocss85

that only works a tiny bit. your not gona make up a .020" difference there. I had them sink my valves .005" when I had ETP do my valve job. but, you hurt flow when you do that.

what did you degree your cam to, did you leave it 0 and set ur limiter to 6,800?.... im goin with a 112 LSA.

TheLS1Kid

iTrader: (12)

Mine was installed dot to dot meaning it was not advanced.

To be honest I have no idea what my limiter is set at, my shift light is set at 6500 so by the time I shift it is probably at about 6800.
