Here's a vid of my dyno run. Over all I was ok with the #s the last run was at 498 and this run was 495/465. Note this is full street trim, AC, OE water pump etc.

Maybe with a cust cam for the LS3 I could net a few more ponies. The cam in it is still from my 243 heads. Specs in sig.

Yeah, for the LS3 heads you might want a lil more split between Int. n Exh.

But those numbers are not bad at all for a 408 ! I'd leave it !

Cause if you change the cam, ur prolly gonna need another tune ~ $

I could change the cam for my car, but it runs good 4 me. In my line of work, "if it's not broke, Don't fix it !" LOL...

BTW, what brand are those 60lb injectors ?

 

Awsome numbers !!!!!!!!!!!!

 

Nice.. I'm interested to see what my 408 with L92 will throw down.

I have a close split Cam aswell.. 243/247, .621/.612, 114+3LSA. I had this spec'd by Patrick G.

There was a discussion a while back on how the close split Cams were throwing down less numbers on the Dyno compared to a wider split, but the close split ones were faster at the track.

 

Yeah been thinking hard about the cam swap.

Going to start another post about my intake leak. I'll get a few more HP when fixed.
