Should be just fine on stock internals, it will already have the nicer connecting rods that will handle 700-800hp easy.

 

So im looking into the 212/218 600/600 camshaft, so to my understanding, the procharger shines in the top rpms, so would this cam give me the power I need down low? Mybad guys for asking alot of questions, don't know much, want to gather as much information as possible

 

It will help down low, but something to consider, with a procharger, you lose some down low because you aren't building boost yet, but you are using power to spin the blower. Does that make sense? Turbo and SC guys go back and forth on this for years.

I wouldnt worry about it, what it means is that your cam choice is a little more important,

I would definitely consider the 212/218, but personally I would do the .550 because you only want ~460hp. Springs are cheaper and the cam is nicer to things in the valve train with lower lift. Get the 112LSA to help the bottom end.

212/218 .550 112LSA, trailblazer converter, 1.75 long tubes, 10psi from a P1 and do a tru trac, you'll have a handful of a truck that's mild below 3-4k, romps up top and doesn't leave you bored

 

Good catch! I forget he mentioned 4.8!!

 

Agree with this.

I run 212/212 .556 112LSA and 9.5PSI (boost setting #1) with a 72mm turbo. I am running 3200 stall converter and 3.73:1 gears. The rest of the internals are 100% stock except for the valve springs. I do recommend some good springs because up top you'll get valve float with that lift on stock springs.

FWIW, I've been running ~13-15psi boost for 2 years on stock 4.8 LY2 internals and on a MAF only tune I put down 519/551 on the dyno. I left alot on the table in the tune being conservative with timing and my MAF curve.

 

So then I don't need to change lifters? Only change to quality springs?
Do i need to tune my truck after I install the new camshaft?

 

1. Do you have to, no but it never hurts. If the cam lobes look mint, just slap the new cam in. Personal perference there in some ways I guess.


2. Yes, you should change to a better valve spring.

3. Yes, yes and yes. The vehicle must be tuned, there is no other way around this fact. The stock calibration is made around the airflow/fueling requirements of the factory camshaft, changing the airflow into the motor at any given time with a larger camshafts requires a tune.

 

What kind of quality springs should i get? Anyone have any suggestions?
