New Best Time!!

[bsn1989]

Hey everyone,

White Lightning ran its best time yet last month.

It ran a 13.1 at 104.83 with slicks and "skinnies"

Anybody want any specs on it, I'll be happy to share.

Nice...smells like at least ~ 430 hp to me

Ha, maybe at the crank. I would guess 300-350 wheel.

I'm surprised you can row that 5LM60 fast enough without grinding the piss outta the syncros.

Awsome time though! I used to daily drive a 13.9 car but I've only been below 13 a handful of times

I'm not familiar with that cam. Got more details - roller/flat tappet, duration, lift?

Sure thing. It’s a hydraulic flat tappet camshaft. Specs are below.

You must be registered for see images attach

Ha, it is a unicorn, the synchros are silent in this thing. It gets new GM fluid twice a year though. I swear that’s what keeps it alive haha

Thanks, I have Summit Racing (Trick Flow) 170CC heads and the Lunati Voodoo 10120700LK with 1.6 full roller rockers 466/484 lift and 207/213 @ .050" in my 350. I wanted to go stiffer but, I still need to pass emissions. I was hoping to get ~350HP - don't know yet until I get done tuning.

FWIW here's a calculator you can punch in your vehicle weight and other stuff to see estimated HP, ET, etc...
