Trying too see how many others are in the 9"s with the L92 topends and how the combinations vary from mine ? any hydraulic rollers too ? pump gas ? what you got ?

 

Mine's a hydraulic roller. Runs on 110.
I have a stock ported manifold.

how much do ported l92 heads go for ?

 

Texas Speed seems to have the cheapest ported l92 heads at roughly $1,100. You're looking at spending more for WCCH, and greg good heads.

 

my motor is still being built, but im hoping for low 9's - high 8's

HKE 408
WCCH L92's
Beck SM intake with some n2o

it will be a hydraulic roller and should be spinning to about 7300 rpms's or so but we will figure that out once it is getting tuned. And will be run on 93 octane with around 11.3:1 compression and c16 in the stand alone.

 

I'm building a 421 with hand ported L92's. I'm also looking at spraying, how big of a shot do you plan on going? I am working with Thunder Racing on getting a cam spec'd, and I plan on using the stock L76 intake. How friendly are these top end setups with juice?

 

im not using the l76, but my whole setup is designed for a very large shot so as long as you have a good flowing exhaust and a well spec'd cam to get that exhaust flowing out of the head then it should be very good for nitrous. but a very important is the cam being spec'd while keeping nitrous in mind...

 

I plan on keeping the cam somewhere in between nitrous and n/a friendly-hopefully only limiting me to a 200 shot. With the pistons I have I most likely shouldn't do more, haha. Do you use a plate style w/carb or are you still fuel injected?

 

Good ET!
What is your race weight?

Thanks man. Raceweight is about 3150 lbs.

 

Mine should be easily in the 9s on the motor as soon as I get the suspension and ignition lined out. It is a 438 inch, iron block, hydraulic nitrous roller with L92s with just a nice cleanup on the ports, no major work done to the heads. It runs all day on 91 octane with an out of the box L76 carbed intake and 750 Pro Systems carb. I have had a lot of trouble with the MSD 6LS system so I am switching to a front distributor. Next major order of business is an anti-roll bar to get the 60' times back where they were when the 396 LT1 was in it.

No one is "easily" in the 9's on motor-much less a hydraulic on 91 octane at this cubic inch range. Nitrous motor too? This I gotta see!
Post back up when you run the #, then I'll believe it.
We don't bench race on this site-since you're fairly new I figured I'd let you know.

6.48 in the 8th before....

lately ran a 6.6 with 1/2 that amount of nitrous and alot more weight.

Just waiting for October...... mods in link in sig.

 

This is true. It's deffinatly not easy N/A.

 

mine is still fuel injected im running a beck sheet metal with a 3 stage direct port. its in the nitrous outlet thread in the nitrous section. its the black powdercoated beck

 

what issues were you having from the msd box?

im doing a 408
11.5 compression
wcch l92 head.
want to stay around 7000-7200 shift point. can i stick a cam in it that will get 9's on motor?
