Whats your current setup right now?

 

ms4 cam
prc ls6 heads
ported 90/90 intake/TB setup
pacesetter LT's with custom 2.5 xpipe into 1 chamber race flowmasters
lid
Vig. 4k stall
410s
weight reduction
dynotune

race weight is 3200 right now.. havnt spent any money on it though.. if i spend a few hundred dollars i could get under 3000 pretty easily...
right at 425rwhp...

havnt been back to the track with the heads on yet... im expecting a 7.0@96.. 1/8 of course..

 

sorry..

of course i have all the supporting mods with my stuff..

dual springs, ported oil pump, ls2 timing chain, push rods, yada yada yada..

 

Ok..It might be nothing it might be something...This morninig, i checked the coolant..and looked dirty as hell..Like brown almost..The last time i changed the coolant i put Dex and water..50/50 mix..I put Dex in the coolant resivor and it looks like the dip stick attached to the cap is kinda melted??..WTF??.

 

the actual coolant/water was nasty.. or just around the top that you screw off?

 

Both to be honest..

 

Flush it real well and switch to the green stuff. Dex-cool + air in cooling system = brown sludge.


Having said that I have a combined 268K miles on my Z-71 and T/A running Dex with no issues..... Weird how some people do though

 

hey man sorry so long on response.. i took a trip out of town for the weekend..


drain everything.. fill it back up with dexcool and report back!

brown ugly nasty stuff on the tops is no biggie... thats just moisture and stuff mixing together.. if its the water itself, thats not awesome.. haha

 

When you say drain everything..Take off the Hoses as well?

 

While the car is idling.....
Turn ON your heater to flush the core and undo the top radiator hose from the rad. Run water through the rad. cap with a hose so it doesn't get hot but just cycle it through top hose till it comes out clear. I just put a slow trickle in the rad. to make the t-stat open more to speed things up and just watch the temp guage to stay safe. When it is clear. Drain the remaining water out of the petcock and refill with 50/50 mix of green stuff and distilled water. Burp it of course and fill the overflow bottle. DONE

 

Ok..Did all that came out good..Thanks everybody...Moving on.....I SADLY have 806 heads,(98) T/A..., and i purchased some 241's, i can put them on with no problems..becuase i didnt change the intake or cam yet..Should i wait or see what it feels like?

 

id hold of on putting the heads on until your ready to do the cam swap, or at least the intake.....

you arent going to pick up a **** TON from the heads.. so it will be a lot of work for no huge gain.... id do two at once.. or better yet all three... will save you money too.. you wont have to replace oil antifreeze etc. 2-3 times, just once..

 

Those heads will pick you up nothing unless they are ported.... 241's MAYBE have 5 hp over 806's....

 

Ok..No Worries..Deezam..Ported..Ok will have to look for some shops..Not Hogged out..But Nice ones

 

yea you are looking at 5-8 max..

dont know how much you spent on them.. but if i were you id try to sell them for whatever you can and get some stock ls6 heads (of course ported would be better).. but you dont have to worry about getting someone to port them and all that and 243s should pick you up about 15-20rwhp...

 

I got them for 135 with Comp Springs (.600 lift),

 

good deal... arent you going with a high lift cam though?


if so sell those heads with springs.. buy some stock ls6 heads and some double springs...

 

torquer 3 on a 112 and AFRs/ and ported FAST youll be doing well

 

hes not looking to spend that much.. although it would be a nice setup..

 

Yeah I am..I settled on the T2 or T3..Most 243 i found are for 300-500 bucks..The Ported Fast vs Ported LS6 dosen't make that much difference in my opinion, But i like the setup CAMAROZ28AQUINO said minus AFR..
