Breaking stuff with nitrous and not getting any traction is getting old so I'm going to stay out of it for a while until I can buy a direct port, bigger slicks, and a dedicated fuel system all at once. I got a new cam spec'd and would like to know if someone is running a similar cam. It is smaller than the current 239 251 so it should make some more usuable power.

Cam recommendation: (2000 GMC Sierra ECSB with forged 408 short block, 64cc ported Patriot Stage 3 heads, .040” MLS gasket, FAST 90 intake, 90mm TB, auto with 4000 stall, 4.10 gear, 1 3/4” long tube headers with no cats, 6600 rpm shift points, 6800 redline)
235/239 .621”/.624” 110LSA +1 advance (with 1.7 ratio rockers)
Comp LSL/LSL lobes 54-000-11 3 bolt cam core
13019R/13020R HR110LSA +1 advance (109 installed intake centerline)

I ran 12.3 with the current cam and I've never been tuned for strictly NA so If I can do 11's I'll be happy for now.

 

sounds like a plan to me going to sound BA

 

No idea, but I can't wait to hear the chop, gotta get vids, lol.

 

Went ahead and ordered the cam. I should have idle clips in about 2 weeks. Should I do cut outs or full exhuast?

 

Full exhaust imo.What did you have in mind as far as set on both exhaust mentioned above?Btw did you spec your own cam?

 

I was referring to the video I'm going to post. I have true duals and cut outs.

 

very similar to my cam, but mine is on a 112

 

I like the way your directport looks on the sig. Wan't to trade me intakes plus cash for yours?

 

stay with full exhaust, i lost power with cut outs

do you have 3" exhaust ?

 

how are those heads with the 408? Are you running dished pistons? Just wondering what kind of compression you are running?
