Hi guys I have a L96 with F35 cam, slightly milled and 3 angle valve job heads, 102 mil TB, ported stock intake, running on 91... I'm wanting to pick up some more on my top end and I was looking at the Fast 102 manifold or a 102 holley high ram as well as switching to E85 do you guys think it would be worth it or am I better off saving money and putting it towards going 408? Also in terms of drive train I'm on a 4l80e and a 4200 circle D stall

 

Hiram will let it have more high rpm air especially since your converter is so loose it won't hurt the low end.
have you had it on the dyno to see what the power is doing currently?

 

yes made 440whp at 6400rpm carried nicely until 7k so i shift at 7200 and 428wtq at like 3500 if i remember correctly was dynoed at 2500ft elevation but it's driven at sea level
I know it's not possible without a 408 but I'd love to see 500whp and a 11.xx quarter with the truck

 

Heads/cam LS3 will make 500rwhp.
227/237 cam motion titan 3 cam in a LS3 with just a milled and cnc job on stock heads and stock intake thru a manual will make 480rwhp on E85. So a bigger cam and better intake will make 500 easy.

Now it's a 416 with an equalizer intake and better heads so hoping for 625
