Grey Matter, it only takes set of heads and a cam and tuning. Not that difficult at all and really doesnt cost that much. Cam (400), heads (1400), tunning (350)
Thats not alot..... the stock 243 heads flow just as good an majority of all the 2500 head w/ same valve size

again we arent saying it cant be done, and iirc it has been done, but with $$$ heads, fast intake and bigger cam, all things you arent planning or mentioning on doing?
best of luck on your build, id love to see you prove us uninformed board members wrong..

Lm7 are around 350ish at the crank. To many magazines have gotten this result out of junk yard 5.3's. I have read the articles where a 5.3 w/ 235 heads (after market) and cams putting out amlost 500 crank hp. Depending on your transmission loss, 425 rwhp is obtainable. You can believe what you..
ALL,
I am looking to beefing up my 5.3 engine. I am looking at one of these cam combo kits. Please help me determine which kit is the best bang for the buck. This will be in a GMC Typhoon, the heads will be stock.
I would like to know what HP gains could be achieved with these kits, and if the prices are good for the product I am getting. Thanks in advance

Instead of everyone telling me what will not work and start saying what will.. no one has stated what they have done and their results. If the magazines are getting all this crank hp why cant I? I have read several magazines that have tested head and cam pkg, getting over 450 crank hp..... either you are here to help or not. If not please stop posting. FYI, saying the gains something wont work is not help

Ok, I see part of the problem here. Most of us are talking hp to the wheels and apparently you are talking hp at the crank. Heads, cam, headers, and intake manifold will indeed get you 400+ hp at the crank with a 5.3. But, 400 to the wheels is a whole different story. It's one thing to make high rpm peak hp and another thing to have driveability and usable mid range torque.
