Louis, chime in please.
Louis, chime in please. Louis,
I saw your other posts in the turbo sizing thread on a 348. I'd like to pick your brain on the same questions for a 5.3. You pushed a ton of water at over 1khp. Since the 5.3 is a more stout block, how much do you think you could get away with with thick deck heads (TFS 215s seem to be one of the only options) before you have head gasket issues?
Also like to hear your opinion on how much the decreased displacement would affect spool. I'm going to be working on a 800-1khp 5.3 project probably this summer. Would you go with a big single or twins? Would it be a good idea to go solid roller and rev higher?

i too am considering a 5.3 build to make better use of my turbo. in for the same thing so hope you don't mind me asking OP, thoughts on a 47-88 turbo with a 5.3 @ 9:1 cr? i'll delete this if you'd rather it not be in here OP and just watch for suggestions.
I have zero 5.3 experience, but that wont stop me from recommending or atleast pointing you in the educated direction. Will you be using a stock crank/rods/pistons? Or building the engine?
keep in mind that one mans 800 hp is another mans 1000 hp. 800 rwhp through a glide is a tough number to pull off on stock internals, thats a lot of parasitic loss through the converter, gears, tires. 800 rwhp through a 6 speed is a totally different ball game
My suggestion will require more leg work than any other, but you will become a student of your car, and the tune up. Dont be afraid to tear the heads off it and inspect, and check plugs often!
Start out small and work your way up. If you are class limited, keep that in mind.
Solid roller isnt a bad idea right off the bat, depending on your turbo choice.
Give me more data to work with. Car, weight, ET/HP (1000rwhp?fwhp?) chassis, trans, budget, etc.

The more the merrier, no issues with your question.

I visited your shop about 10 years ago. I was out for a job interview in Tx and your Dad ended up giving me a ride to the airport in his black C5 with the stroker motor and yellow rims. I still remember that ride. Tell him I said Hi and I hope he is doing well.
Keep the RPM low (sub 7k) and I would run a single T4 7175 or 7182. You can grow this setup ultimately into an 8285 billet, which would support more than the gaskets can seal.
The 7175 will spool well and still be fun to drive. If you really wanted to stick to super fun, and so so HP, but same foot print as the 7175, you could bump down to a 6875. Peak torque would come up much quicker and be more enjoyable on the street, but peak power would suffer.
As far as heads, The TFS with the LS9 gasket, and a good stud will seal fine for your goals
I remember your ride, I think you posted about it. That car was fast! 500 rwhp back in 2000, through LS6 heads and intake!
