is 420hp possible? 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?

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.
