blew the h/c ls1 so i ordered a 408 from texas speed...i ordered there
-408 shortblock
-Eagle LS1 forged crank 4.00 stroke
-Eagle LS1 H beam connecting rods
-Diamond 10cc pistons
-texas giant cam 248/254 .611/.613 112 w/ pushrods
-LS7 lifters
-Fast 92/92
Im using the heads from my LS1 they Patriot LS6 style heads...59 cc i was told these are gonna hurt me a little bit so just curious... compression is gonna be 11-11.5 / 1

now all this doesnt ship out til the end of the week...so im curious if anyone with a similar setup put down? this is a street car as well as a track car too thanks for anyone who can actually give me a real estimate on power here...i just cant wait to get it all installed THANKS!

just from the looks of it i would venture out and guess 465rwhp and 420tq give or take a few hp. with some better heads i would have said more, but those wont flow well enough to make great numbers

I'd say about 480/440

Cam is a little too big and the heads are not exactly the best choice. Maybe 470/450

cam too big? its the cam they recommended?

buddha845

iTrader: (3)

probably a bit too big for the heads but youre obviously better off upgrading your heads later on then putting in a smaller cam to settle for that set of heads and a lower #, 475/420 doesnt sound too far off

slow trap

iTrader: (22)

i'll say 480 rwhp or so with 450-460 rwtq. there should be a few combos similar to yours on here so maybe someone with a similar setup will chime in.

"all" i was wanting was 500 haha oh well....i do plan on going with much better heads down the road...i was hopin someone had a similar setup but i looked an didnt really see anyone...thanks for the estimates...and keep em coming...i will let you all know what it actually puts down once its up and runnin motor doesnt ship out til this friday or so...the other stuff is on its way..got pushrods today

500 would be easy with a different set of heads and a different cam.

momartin22

iTrader: (2)

welp damn...oh well...its what i have now...so when i get money for the heads i will most likely get a custom grind cam to match anyways...

firefighting1101

iTrader: (48)

yeh that cam is too generic for a build...a build like this needs a cam to match. if you had a custom ground cam to match your heads you currently have you may be able to pick up some hp. but even then its a huge cam for a 408. but good luck, and i hope you prove us all wrong and pull over 500

Fifedogg has an LS2 402 with an MS3 and stage 1 ported 243s and hit 502rwhp/475rwtq, I saw his car for the first time last week, you can hear the cam but you would never know its a 500+rwhp car.

EDIT: Hes also still on a 10 bolt, waiting till it breaks to install the 12 bolt.

His car is awesome and deceptively fast. Sounds basically stock with a slight hint of cam lope. Completely stock exterior. Stock interior. Little to people know he has a 402 with 500whp under the hood.

no i meant rwhp and he knew that...i have a 9'' w/ 4.10s and i am a six speed...the guy who is tuning my car got 470 rwhp out of g5x3 basically the same heads and fast 90/90 through a 9'' and on some 26x10.50s
