I think that cam is a little on the big side, the XE274 will run better in the mid. I build a 355 combo out of a 96 up factory hyd rr block, that makes 458HP/475lbs with 10:1 CR a Isky 225@.050'', .540'' hyd RR, and ported vortecs. I have ran the next size up 234@.050'' .550'' and made 470HP/450lbs.

Like i said, that was the cam that Comp reccomended, and i made sure to note that it was going in an extended cab silverado. Also, i think that i am going to do a 383, because the machine shop doing my heads is an eagle wholesaler and i can stroke it for cheap. I think that then the cam will be about perfect due to the increased displacement.

I take Comp's recommendations with a grain of salt...if you call 3 different times with the same set up and get 3 different reps on the phone, you'll probably get 3 different recommendations. Since you're talking 383, that cam will be more suited than if it was a 350, but it's still pretty wild and will have a rough idle I believe. I'd really like to hear a video of it if you pull the trigger though 
Your right on track with the 2800 converter for this set up, have you decided what brand converter that you're going to go with?

Idk about the converter, im new on them so i would take any knowledge you guys are willing to give! The B&Ms are cheap, and being 17 and in high school, my budget is a little low. I would like a Yank though. What about a re-stalled stock converter?

383 will be alot better but that cam is still on the bigish side. Would be great for a car but I think mid to low 230's would be better for a truck. Comp has a 286-Ah8 thats 236/244, 108lsa I have made good power with it in a 383.

Anybody running a Lunati Voodoo cam? Thats what i was originally thinking about, and i have heard some good things about them. What do you guys think? Nothing is set in stone as i haven't bought the cam yet so i am open to some suggestions!
