Good Enough for Mid Low 10's???
Good Enough for Mid Low 10's??? I've currently came across a LQ9 from a 2002 Cadillac w/ 317 heads. I want to install it in a 86' Buick Regal. I would like to know what would work for a budget N/A setup for Mid 10's to High 9's??
The Regal's current setup is:
406ci SBC
11.0:1 SCR
1 5/8 headers
Holley 850CFM 4150 carb
Dart Iron Eagle heads
PowerGlide w/ 4000stall
9inch w/ 4.56 gears full spool
Cage
Kirkey seats
MSD 2 Step
Trans Brake
Car Race weight is 3012lbs with 10gals of fuel and no driver.
best time is 11.53 @ 114mph w/ 1.35 60'
I currently have a spare 04 Silverado PCM with modified harness, spare LS2 Fuel Rail/injectors/ and intake from my 06 GTO maggie swap as well as a couple sets of stock 5.3L heads. Have a full spare set of ARP rod bolts as well.
So what are the best options with the stock cube Lq9 N/A??
Port and Mill the stock 317's maybe down to 66cc combustion chambers or look into some aftermarket heads??
Install a Thunder Racing TRex cam/MS4/SNL RedLetter??
I would like to use the 4th gen Fbody LT's.
Would it be better to go with the MSD programmable Timing Box and super victor intake??
Open to all ideas and suggestions. Would like to get the setup ready to go before spring!!

I am thinking your going to need 500rwhp to be mid 10s and 600 to 700 for 9s. I would look into TFS heads and bigger cam to get close to 500rwhp. Or do the 317s/Ms4 with nitrous would get it done. Could do L92s and matching cam with spray also.
Found this article on the search and was thinking if he was getting these times with less gear and off the foot brake a set of ported 317's should flow close to stock L92 and have a little more compression. Going of the Trans Brake and Powerglide should give me a little better result.

get some 243 heads, a supervic/4150 tb and a big cam, you should be where you want.
with a cam/ nitrous 6.0 in a 3000lb car you'll easily be into the 9's

Verdad Gallardo I would suggest a aluminum short block for more weight savings. Your gonna need as much weight saving as possible to get close to that goal especially trying to do it n/a stock cube! Any idea of what the 406 is making for power?
Just off a desktop dyno somewhere around 420bhp. Probly just clone the burgers build on his 84' cutlass gbody. Has more weight with a Th350 launching on a footbrake running 10.6xET on his Lq9
not hardly... Ive seen cars go 10.9x or better at 3100 to 3200 lbs. with the power stated above. Another example would be the fastest cam only list on this site. Take a look if you would before posting
I just figured if RobZ could do 9.98ET in a 3100lb c5Z06 5.7L with some Trickflows and Cam I might be able to take a 6.0L that weighs close to the same with a 2 step and TransBrake on a stalled Auto to around 10.5 on stock castings with a good cam. Looks like my main problem is PTV clearance.

Figured I would update the parts list with the currents parts I have gotten for this project.
First off reweighed the car with 6 gals of fuel, full race weight on the 406ci Iron Headed SBC it weighed in at 2980lbs with NO Driver. (I'm about 170lbs)
UPDATED: -02-27-12
Anyways the parts list:
04 CTSV oil pan
Stock Bottom End LQ9 (364ci)
Trickflow "AS CAST" 220 cc heads
64cc Chambers, Ferrea 2.04/1.575 valves "LS1 setup"
.660 TEA Valve Springs
Comp Trunion Upgraded Stock Rockers
Trickflow 7.500 Pushrods
TEA spec'd cam 240/244 .613 .596 109LSA 107ICL
Edelbrock 1.75-1.875" Stepped LT's with 3.5" Collectors Ceramic Coated
MSD 6010 24x Control Box
SLP Heavy Duty Oil pump (Blue Sping for now)
ASP 25% Underdrive Pulley
EWP
ARP Rod Bolts
ARP PRE 04 Block Head Bolts
GM .051 MLS Headgaskets
850 CFM Holley 4150 Carb
Powerglide w/ 1.76 First Gear and Turbo350 Main shaft and Trans-Brake
Coan Stall set to flash between 4K-5K depending on Gear, Weight, and Engine
33spline Full spool 9inch 4.56's
Vic Jr. intake
Trans Dapt 4595 mounts
JW Performance 93019LSD Flexplate
Still needing Alternator bracket, Starter Bolts, GM Flexplate Bolts
Any suggestions or comments??? Is it capable??

Here's an old pic of the car and the engine details on the 406SBC that is currently in it:

And your combo is MORE than capable at 450-475 rwhp to run low 10's high 9's with a 60' in the high 1.20's low 1.30's.
My car makes 405rwhp through an unlocked 5000+stall, TH400, spooled 12 bolt, 4.11's, 28" tire with 20pounds of air. Not a dyno queen set-up by any means.
The cluelessness of some of the people on this site blow my mind sometimes.
