Have a lq9 370 stock crank rods diamond-2 pistons, 232/236 cam hand worked 243s an stock tbss intake. Put down 384 to wheels. What are some heads or heads an intake to go with to get more. It's a 07 tbss
staying n/a btw

 

I’m an advocate for the 706s. The added compression will make it pop a lot harder.

 

Without spending a lot of money on an aftermarket intake for 7-10hp, I don't think your missing power in the intake

ported heads might help, LS3 heads might help peak power, but will show losses under the curve for what I've seen in graphs

what's the current compression ratio and how much timing can she take? What head gasket thickness and LSA on the cam?

 

What are all the cam specs and how far are you spinning it rpm wise? What’s the CR? What fuel? What’s the exhaust
setup

 

Honestly not sure on the cr. It was in it when I bought it... but has long tunes magnaflow an its 93*... I believe when I got it tuner said it had 26 or 28* timing in it an got it to 20-22 dont remember an made 17 more hp from the other tune...

 

Cam is a 232/236 .625 112

 

What rpm was peak HP

Tranny 4l65. Mileage ? You running stock convertor , If so 1st upgrade you need to do.. stock convertor can have as much as 20% slippage its TBSS running stock rims tires or big heavy 22-24s , Heavy Spun weight kills Dyno numbers. Your 384whp is no bad. I’m running 6.0 w 821 heads with BTR 226/240 supercharger L96 intake @390wph. Thru 4L80e w/ stock convertor my tuner guess my convertor slippage is 15-18% Good convertor will be in 6 to 8% slippage ..

personally the TBSS intake is great for street, the only good upgrade is $$$ Fast intake ...

What you have for exhaust?

 

you can lock the TCC on the dyno, should be 0% slip

No use swapping to light weight wheel tire combo if you're gonna run the heavy stuff on the street. Unless you want glory pass numbers *shrug*
