skip the big ricey choppy cam .

just toss in a pete jackson reg gear drive set .

i did this years ago and every one asked me what did i have under the hood of that truck .

and bbc cam swaps from stock almost always = valve springs .

truth.
 
Why would you want to kill low end torque on a BBC ?...especially in a heavy truck...it'll make city driving a pain,you'll foul plugs,and get 4 mpg..
I'd leave it as is and just turn in the carb mixture screws till it lean misfires at idle,no one will know it doesn't have a hot cam ..
The "poor man's lope"..
 
You can build a big block to sound great and still have incredible bottom end! It's all about the combination of parts. The truck in my avatar will literally blow the 37's up from a dead stop idle. I've built a few like this with great results, but it's not gonna happen with peanut port heads. Grumpy's is a great resource for the BBC, just remember that most of his stuff is geared towards race car stuff.
 
Well if you have a 350 now, I doubt you’ll notice a lack of low end torque w a 454 and a “too big cam”
But I would surely go w a 3/4 race cam for that “sound”
 
I forgot I had that cam in the first motor in my Blazer. These clips should all be that cam (basically a stock motor with oval port heads and that cam) -

@urbex I have 4 video clips left on my old photobucket page ("nvrenuf_k5", pg 4) but the share links aren't working when I copy them. Here's one, it only works for me if I copy / paste in my browser, then it'll play.

Is that the case?
That might be what is wrong with my carb on the 402 bbc in the c10
