Ive heard .1 to .2 but nothing concrete about that! Some say a noticable SOTP feeling and some say nothing. I went to the track 2/9/08 and with 228R, LT's, 3800 stall, P&P throttle body, LS1 intake, Tru-trac, 4.11's and 28" ET Streets i went 12.90 @ 101.75 with a 1.78 60'!!!! With the heavy *** 20's (75-85#) up front worth probably another .1 if i went to a stock wheel tire combo. now ive added (yesterday) a ls6 intake and i noticed a nice gain in the entire RPM range worth .2 or so!!!! Im asking would i notice the same gain with the pulley? maybe between intake and pulley and tire/wheel up front .4 - .5 gain!

 

i dont think i gained much, if anything but it does make driving more fun. the throttle response felt alot better.

 

well as a look more into it, it seems to help more with the more mods you have. So this would be my last bolt on according to bolt-ons besides elec. water pump!!!

lol....do they count as a bolt-on since they see oil and water? Im going to start with some stock 243's and send them to be ported and valved whenever i get some more money

 

might wanna just start with the 799s then, you should be able to pick them up for cheaper

 

technically they bolt right on i would wait until you have enough money to do it all at once. swapping heads is a PITA.

 

lol thats what i would say!!! most dont consider it that way though, I DO

beastmode- hows it goin man havnt heard from you in a while! i like the idea of the 799 heads but they have gotten just as popular as 243's when they become avaliable.

 

patriot will sell you brand new 243 castings with valves for $425. cannot beat it with a stick

 

not much bud, saw you got in the 12s, congrats

so you mean the 799s are just as much now?
