Hey guys I have a 00' SS with 41k on it. I just did some things to the car and have been fooling around with the idea of H/C combo and see what others are running in a street car and also what else would be needed to compliment a H/C combo to still run good as I do drive the car to work etc granted the weather is cooperating. So far the car has LS6 intake, Pacesetter LT's, TSP catted Y, SLP LMll cat back, Powerbond underdrive, and a tune by frost. I am very hapy with the car but would like a little more. I have been doing some reading and seem that 243's may be a viable option for my need over my 241's. I would be redoing all springs valves seats retainers and rockers while I have heads on a bench which would lead me to another ? what are good parts for the heads, I still want the car streetable but am not sure I need a custom grind cam for my wants? SO if anyone has any first hand experience on setups or opinions on h/c combos and head parts or even HP numbers on a similar setup that would be great, also any other things you may upgrade at the same time

For a daily driver AFR 210cc heads should be the best. More power everywhere than 230+ cc ported ls6 heads and should drive like stock.

For a cam it's more to what you want then anything. A 228r is a good off the shelf cam that should be a great cam for daily driving and still make around 430-440rwhp with the AFR heads.

If you would like to keep costs down and don't want to spend $2000 on heads, I'm porting some 241 heads right now and they should flow between stock 243s and ported 243s. I could let them go for only $500 with valves and stock springs.

So you even think stock 241's ported w/ stock valvetrain with the 228r would make a good street combo, what would numbers look like outta this combo versus the AFR's. If i were to keep my 241's what would be some good valvtrain to look into. I am thinking now the 243's may just be too big for a cam I will most likely end up with?

Really 430 with the 228r and 210 AFR's?

Also if i decide to go with other heads what is something comparable to the afr's to work with the 228r other than my 241's ported, all i see for the afrs on a ls1 are the 205cc 66cc chamber

For a street car you would make good power with ported 241s .

RedmaroSS

Have you seen numbers before, what? So for the street car you think the 241's ported with the 228r would be a good choice and not drop the coin on the afr's? What valvetrain would anyone suggest?

I have TEA stage 1.5 241's. My cam is thunder racing 230/236. I could daily drive my car but i don't for lots of other reasons.

Car put down 440hp/400tq.

Also my car is a M6, has fast 90 setup with true duals.

Make sure you get a good tune.

RedmaroSS

Anyone else think the ported 241's w/ new valvetrain and 228r is a good idea for a Street car? What valvetrain would be a good sugestion also LSA?

Im a big fan of 114 lsa still sounds good and widens out the power band so its alot more fun to drive slow (pulls better in the low rpms you wont have to turn 5k to feel it) as for valve train I vote pac beehives if youre under .625" lift, and the lobes aren't too aggressive. You could go with a double spring but unless youre gonna turn 6 -7 grand everyday on your way to work it'd be overkill, and then of course hardened pushrods don't hurt. me personally I run the comp 224/230 .581/.592 114lsa in my DD with no prob, and it kept up with my buddies dyno tuned 233/239 cam @403 hp. Both of those cars are cam only (stock 853 heads). 228r would probably run better in the lower rpm and be easier to drive, but if you want her to thump, make all your buddies drool and really like that throw your head against the headrest feel dont be afraid to go with that tsp 233/239 even. That buddy of mine DD's that. Gonna need prc.650 lift springs though

I would just buy 243 cylinder heads and forgot about ported 241s. First you don't have to worry about port work not being correct or uneven from cylinder to cylinder. 243 heads have a 210cc runner which is pretty dead on for a street car on a ls1 just get a quality valve job on them and mill them down a bit and run a cam similar to your 228r and its an easy 400rwhp with even a ls6 intake. You don't even need to find a sodium filled valve head either if its just a street car, so even 799 castings work and will cut costs down. if you put the machine work into them and clean them up should flow around 280 cfm and you wont have to worry about leaks or siliconing things like ported 241 heads. Last but not least if you ever wanted to move up in cylinder heads even after getting the 243s slightly milled and the valve job on them they will sell pretty quickly and retain their value pretty well where as 241s you can barely give away.

oh btw i just noticed you were going to get the SLP lmII that 233/239 buddy of mine has the longtubes ORY and the LMII and its a freakin screamer. I had to watch the tach when we raced because i couldnt hear my own longtube ORY and 3.5 inch mufflex spintech. depends on whether or not you want EVERYBODY to know youre coming or not but id suggest either of those exhausts
Good luck deciding, sorry to throw all that in the works

RedmaroSS

I alraedy have the LMII, 3" TSP catted, and longtubes on the car along with a LS6 and P&P TB what heads is your buddy running on the 233/239 cam? My car has the 241's on it now am thinking of just porting those and putting new valvetrain in instead of running 243's which most seem would be overkill? I just need to find a new valvetrain to use, i want to replace everything so i get a brand new top end valves, seals, springs, retainers etc etc...You guys think the 241's ported are sufficient for the 228r or even 233/239 114lsa, just need to find out i guess whic cam would be better for a street car, i do drive the car if the weathers right and would like to keep it that way but dont want to dish out coin for minimal gains

RedmaroSS

I notice the difference in powerband in the 228r and the 233/239 is very similar with the 233 239 being a little better, anyone running this cam in a daily driver i may be going thisd route now, just need to figure out a set of heads and valvetrain now?

Also anyone ever try the PRC spring and pushrod kit...showing good to .650 which will suffise both cams and a 7.400 hardened pushrod?

sorry i know this has nothing to do with what your asking but would you happen to have a sound clip of your car with the slp lm2 because i have a similar set up but would like to hear it with a cam because thinking of doing tru duals but also would like to hear how the slp lm2 sounds wit the cam

another vote for the 233/239 and stock 243s.

...will also want to consider clutch/stall, and gears.

realistically, what is your budget? i would look in the classified section for heads to save a lot of money. however, if you were to buy afr heads and custom grind for example, your looking at about 6k installed with a tune (this would be a safe guestimate). your power is restricted by your budget (stating the obvious). GL! and it's good to see someone researching an not asking retarded questions without research

Buy the best heads you can afford and a good matching cam. Those AFR's are super and TFS too. If not you will want more soon....Don't do it twice like I did....

Trust me on this. I have had my new combo in sig for a month and already want to throw some spray to it LOL.. Gotta buy a 12 bolt first though....

RedmaroSS

I dont really want to over 430HP in the car at all, that is plenty enough. I am thinking more and more now on the 233/239 maybe a smooth 114LSA. I am also thinking the 243's, the 243's should be sufficent for that cam, no? I mean a nice set of afr 205's would be great but the money spent for a little gain isn't really that worth it to me if the 243's will handle the cam. This will be a progression build. Ill start looking for a set of 243's get the valvetrain all setup that I want and in them, then look for a cam. I am also thinking a LS2 HD timing set, and i guess i need to start doing some homework on clutches, car is a M6. Does anyone favor a valvetrain to use. Ill probably reuse stock valves?

ANyone using a 233/239 and have a video clip?

garygnu

look at TSP for valve train parts or a cam kit.there a couple of threads about home ported 241 heads with pics.maybe a torquer3 with a little bowl work and a nice valve job will get 400rwhp.

Throw a MS4 in and have fun. With supporting mods 420 RWHP and 11's.

if youre not really looking for max power do a low 23x/23x cam and stock 243s... should be plenty of power for a street DD car. And youll save a lot of $

Real reason i never dropped big money on heads was because i planned on going to a bigger motor down the road; and then i would have to get new heads for a bigger bore motor...
