N/a in the eights? What combo is it gonna take to run in the eights (1/4 mile)? Please go into detail. Car is a 3rd gen (92 Z) has been 9.20s on the hose. Thanks, PHIL.
Plan on getting there this year. Switching to a distributor and carb. Think I found the right converter and gear. Working diligently to get weight off the car.
440ci
.800 lift solid roller
400+cfm heads
8500 rpm
At this point its all in the set up and alot of seat time.

Didn't Joe Honeycutt already go 8's N/a?. I think it was a relatively small c.i. motor(right at or slightly over 400ci) but had a slipper clutch 6spd, solid roller, and massive compression.

a guy with the screen name camnhawk went 8.9x like 4 or 5 years ago. i believe he was the first in the 8's. the main combo is time and lots of money.

Lots of cubic inches, great flowing heads, high RPM's and super lightweight everything on the car.
Also, plan on lots of maintenance. Lots of wear and tear on the valvetrain, potential short lifespan on the rods and crank.
Where you'd just be working out a run of the mill big block to get these types of numbers, you'd be beating the **** out of the LSX to get into the 8's.

This is a car I put together, Fox Body Mustang, powerglide, SBF.
8.90's @ 152 NA
393"
Yates canted valve heads, flowed almost 400CFM @ .800
Small Solid Roller 27x/28x @ .050 with .8xx/.8xx lift
Cast Intake Single carb, Dominator
14:1
Motor made right at 800 FWHP
Shift @ 9000 RPM
Motor has all the goodies.....titanium valves, retainers, Belt Drive, etc...

the cylinder heads,intake and valvetrain are the main keys,while i havent done any 8 sec ls motors yet,i have done some sbc's and sbf's,they are require the same stuff
good heads-perfermance inductions c5r heads would be best
intake-perforamance induction single plane or sheetmetal
valve train-jesel rockers,.937 keyway lifters,7/16 pushrods etc.
big bore-to allow the heads to flow properly
lots of compression-13+
light rotating asy for high rpm use-alum rods,lightweight crank
rigid block-everything needs to stay were it belongs at high rpms
good oiling system-dry sump,proper windage tray etc.
expect to pay $25,000+ for an engine like this

Sounds about right. But if ya want to go fast, that's what it takes. Doesn't matter what the car/setup is, 8 second setups are 25 grand. Sure you can spend less on the motor and go FI, but at the end of the day it's still all gonna add up.
Scary but this figures about right, 25 grand for a 8.90 setup, and every tenth faster you want to go, add about 1100 bucks. Sounds silly but do the math it works out
