OK GUYS HERE ARE PICS OF THE TRUCK WITH THE HARRIS SPEED WORKS PLATE KIT ITS ONLY HARD MOUNTED FOR NOW SHOULD BE WIRED THIS WEEKEND RAN OUT OF TIME THIS PAST WEEKEND....HOPING TO HIT IT WITH A 100 SHOT NOTHING CRAZY....WILL POST MORE RESULTS AS THEY COME..

Ok guys SDPC has been working on our 2010 silverado 5.3 upgrades are listed below with the dyno sheet....

vvt comp cam custom grind 218/222 .560/.566 lift 115lsa
dyno is on 22" wheels

 

nice numbers! makes me wanna throw a cam/headers on and get those numbers haha.

 

Not bad for a 5.3 and 22s but a bit disappointing when you compare this dyno sheet to a 6.2 dyno sheet. Don't get me wrong the 351hp 320tq is respectable but cam headers and the work to be swapping lifters and the money alone for all these mods I would rather find me a used 6.2 and swap it out and make the same numbers with a stock motor and still have all the potential to make more power.

 

We are not working with a 6.2 let alone with an entire engine swap. Customers have shown great interest in what they can do with a mild cam 5.3 and that is what we are working with. This is a project to gain more HP out of the incredibly common 5.3 while also maintaining the advantages of having VVT

 

Oh yeah don't get me wrong I have seen the potential of a bolt on 5.3 and I think it's badass that your putting those kind of numbers and improving on GMs most common engine. Alot of people won't go through the trouble to swap a motor or just can't and are left with the 5.3 to work with. Thus going the route you guys are taking and spend money to make that motor perform... I was just saying my opinion in what route I would take givin the same amount of work and funds. You guys are doing great don't let what I said take anything away from that.

 

Oh and I was gonna ask how much of an increase are you seeing vvt cam swap only and do you have others then the one you used?

 

We are figuring about a 40 hp gain on just the cam to the wheels. As for grinds i can do just about what ever you have in mind all i have to do is call a custom grind is really no more than a off shelf grind...

 

wow impressive! that 5spd sure helps put down the numbers huh?

 

Thank you and its a six speed automatic

 

Bump for new parts added....
