Default Realistic expectations from this combo?

So I’m planning on the following mods and would like to know realistically what I can expect. Power wise and drivability. The ones with an asterisk beside them are ones I already have.

stock LS6 shortblock*
Kooks Longtubes
O/R X pipe*
Corsa Extreme*
Blackwing intake*

ported 243 heads
TSP 228R-110LSA cam
TPIS modified LS6 manifold
new tune.

im not looking for max power but id
like decent drivability while
making more power than i have now.

My .02
228* on a 110* LSA is more overlap than I would want for a primarily street driven corvette.
The Cam Motion LS1 Titan 4 227*/232* on a 113* will tune and drive much easier and should
be worth 50+ rwhp Alone, Before porting the 243s

I'd place a safe guess 415+ whp.

Stock LS6 nets around 340whp. Add exhaust for 30. Cam for 45. Heads aren't so needed.

H/C is a fun way to go. Consider also a used blower kit from A&A or ECS if you want more power while also maintaining oe mileage and driving under 3k/boost range. H/C when fully upgraded out challenges a blower kit. If you ever sell the car it is easier to sell supercharged or to remove and sell the kit separately and then sell the car as a regular na Z06. Food for thought.

110 LSA will be CHOPPY. That's a good thing IMO

yes I didn’t choose it based on that but it was a factor esp since I don’t care about every last bit of HP. However I’ve also seen that Tick has a cam I’m looking at that also has a 110 LSA. It’s there SNS torqmax stage 2. Just not sure how they would compare to each other.

FWIW I have a similar setup to what you’re looking at doing.

TSP 228/232 112 LSA
Fast 92/90 combo
Kooks headers
Halltech
Unported 243 heads

Made 427/398 on Dynojet
