First engine build here and trying to get a realistic hp number for my build

2005 4.8 gen iii block bored over to 3.903 (346?)
TSP ls1/6 forged rotating assembly with -3.2 pistons
706 heads(not the ones that crack)
TSP torquer v2 cam kit with duals springs
truck intake
unsure of injectors size i would need
ls2 timing gear
will be behind a new t56 magnum or tko600...undecided.

I've seen so many different builds and setups that I'm unsure where I would end up. Thank you ahead of time.

IF THIS IS IN THE WRONG AREA PLEASE LET ME KNOW, STILL LEARNING THE FORUMS.

 

I would get some 36lb GTP injectors. They will do 42lbs with our fuel rail pressure. Those heads with out any porting are going to kill your set up. I would look into getting a stock set of 243's if your on a budget

 

Yea, I've been told these heads will limit the motor, i'll look into some 243's....thanks for the response. I appreciate it.


Any idea where keeping the stock 706 vs 243 would put HP?

 

So many better cam options too.

 

I wouldnt get a Torquer v2 even on a stroker. (And from what I have read and the Valve events I have calculated, this cam isnt the best option for "torque" ) Ignore the cool names. If you got the truck intake and heads and a stroker, clearly this engine is set up for torque, id build for that instead of HP. Call up a good cam manufacture and have them build you a custom cam. The cam will make or break you.

 

Why dish out the money for a forged rotating assembly? Seemed like a poor investment.

 

(Russian accent) 420hp possible but not recommended

 

(Russian Accent) 420 horsepower can be made with alcohol injection by way of Vodka. Everyting is much better wid vodka.

 

Where the heck is the "like" button in these forums? lol

 

(latvian accent) what about potato?

 

(Russian Accent) Da! But Potato become Vodka, just like uhhh... like tomato become ketchup.

 

Might want to use the Dorman truck intake
