cam specs?


I imagine you would crack 430whp, depending on how high you want to spin it.

Oops forgot that, edited, Texas Speed Torquer V2

Anyone else?

A friend has nearly identical setup except for he has a ls6 intake and stage 2 243s but he made 433 whp on the dyno we only have 1/8 mile tracks around here with a 3160# s10 3.27 gear he ran 6.5x in the 1/8 but we have lots of suspension issues were trying to work out also

Man, the truck should be good enough for 11s sounds like.

Any guesses on track times with my set up on a DR?

SteenH

Friends setup (1998 z28)
SBE ls1, 59cc PRC 2.5 5.3 heads(right around 11.4-1)
torquer V2(112) ls6 intake, ported TB, 18lb flywheel, monster STG3
Through the M6 and 10 bolt on what I believe is a happy Mustang dyno it made 460RWHP/430tq. spinning it to 6500

runs very strong, 20 year old kid beating all of the older guys around town.
Car is 4.30 gear/s60 now, track times soon.

I have a similar combination in a 91 Camaro.
LS1 stock bottom end
AI 226cc 243's with BTR springs, milled to 62cc
228/232, .625/.625 112lsa AI custom cam
Fast 92
NW 92 throttle body
Fast 36lb injectors
Stainless works 1 3/4 headers into 3.5in mufflex cat back
4l60e with FTI 3200 stall converter
12 bolt with 3.42 gears

Mine made 434rwhp, 398ft/lbs on a dyno jet. In theory your car should put down a little more with the higher efficiency of a t56, more compression, Fast 102 and 1 7/8 headers but all dynos are different. Don't get too hung up on dyno numbers, the mph at the track will tell the real story of how much power it's making.

I would guess your combination should put down about 450-460rwhp on a dynojet and mid to low 11's depending on how well the suspension works in the car. If the suspension is really dialed in a high 10 should be possible in a car that light.

Keep us posted on the results! I'm anxious to see how your combo does on the dyno and at the track.

Sweet, this is probably the closest build to mine. If im hitting a solid 11 sec quarter mile i'll be happy. I'll post an update once it's in soon. Just bought the UMI k-member for it all and MgW shifter.
