Help me get on track? Hello All,
I am making a transition from the carb world (400 sbc) and entering into the LS world. I have a grand national that I am planning on LS swapping. I want to make around 800 HP to the wheels. I wanted to see if someone here could help me with a decent set up and answer a few questions.
I am thinking of going LQ9 with a single turbo
Holley Hi Ram intake
and that's pretty much as far as Ive gotten haha
Anybody have a car making that type of horsepower that I am looking for (around 800 HP) and care to share your set up? (turbo, heads, crank, pistons, cam, rods etc)?
Would this type of power be able to be driven on the street as well as the track?
Thanks!

Theres a guy here with a grand national running a 300k mile stock 4.8 (stock cam as well) making 800whp with a single borg Warner.
Don't overthink it. You could skip the Hi-ram, run an extremely mild street cam, and with the right setup make 800 HP easily.

What's the name of your youtube channel? I want to subscribe.
I think ported heads on a turbo car is a great way to add 50+ horsepower to a combo without much risk other than the extra cash outlay. Not essential but is def nice bonus power.

People do crazy things daily on stock gen 3 bottom ends, but my personal opinion is anything over 600rwhp is in borrowed time. Throwing some gen 4 rods in the motor would give you that insurance to keep it together at 800rwhp.
Are you shooting for a dyno number or a particular track time?

More concerned with a track time as opposed to a dyno number.
AFR vs trickflow...anyone have any suggestions for a LQ9. Or any other good set of heads anyone suggest? Stock 317s?

You can easily hit your goal of 800hp with stock heads. It's just gonna require a little more boost. If you're on any sort of a budget the money could be better used elsewhere.
ime, stay away from trickflow. all their heads ive ever gotten new needed work out of the box. like loose guides and crap like that you dont wanna mess with after paying 2 grand.

In reality, you aren't really solving anything with fewer PSI except a slightly less complicated tune.
The deck thickness on aftermarket heads is a nice advantage over 1000 HP.
