Absolutely, you have to run a heavy car to ever understand/realize how much HP they eat.
The point of this was really not about the weight, more about the idea that an LT based engine in the right car can go 6's. Not sure many understand that and it's possible today, not somewhere in the future.
You need billet blocks and top line parts to pull that off but any car in the 6's has those same top line parts with billet blocks. But they are all big blocks and that's where this becomes more cool that an LT 23 degree head engine could do this.
So there is a long way to go for what the fastest LT based car would be. With the right equipment, it's somewhere in the mid to low 6'sLast edited by Jeff Green; 03-29-2018 at 10:58 AM.

I was reading the article that super Chevy done on your ride back when you were running the 4L60E from Rossler and your Donavon block was fairly new to the car and you were still running the 8.5 rearend. You were running 9.5 second. The Cage you had to install after 9.99 had to add a bunch of weight.
I will be curious to see what my combination is going to do. If I can make in the neiborhood of 700 to the rear wheels with the weight being 3300 pounds. According to the calulations. If it made those number 9.5 on the 1/4 mile. It's amazing that car that weights 2500 the weight can run 6s and down in the high 5s on 1200 HP. It takes far more horsepower to propell that extra weight not to mention the stress on the parts. That's why when I look at the pro stock class of the NHRA the car body is made out of carbon fiber and the cars are make 1,500 horsepower to the flywheel. And run in the 6s naturally aspirated.
When the discussion of a steel quartes and roof car. The weight that it adds.
There's no aftermarket block produduced. I cannot imagine what the cost of and finding some one that has the ability to machine an aftermarket block for the LT-1 reversal flow ect.

Maybe I shouldn't say this too loud but I own the programming rights to the CNC program for my billet LT1 block. It would still be more money than most would want to spend but I can produce as many Billet LT1 blocks I want. But we are still talking "one offs" so it's just a lot more expensive when a company with a CNC only runs one and not 100.
So you can buy a Billet LT1 block and they do exist, I have one in my car.

Last year was a disaster with nothing but blowing off blower tubes and fireballs. I knew what was wrong but couldn't figure out why.
I have that now figured out. Two test sessions so far this year with 1.3 sixty foots and it hasn't bent the rear end with all the added bracing. Trying to be careful with it so no real passes yet. But have coasted to the 330 in the 3's and to the 1/8 at 6.5 at 70 MPH. Plan going tomorrow for a full power 330 pass and see if it all looks good.
Hope the LT shootout is on for 2019, I plan to be there.

And before someone thinks a 1.3 60 foot is no big deal, you didn't do it in a 4500 car. Go get the salt bags and load your car up until the scales say 4500 pounds. You will either bend something, break something or it will just go BOOM and not even move off the line. I don't think trying a 1.2 60 foot is a wise thing with that much weight. If it just weighed 4000 pound it would already be at 1.2
And as my disclaimer always states, this doesn't make my car better than yours in any way. But you're also are not doing what I'm doing. So I could still have problems even with 1.3's.

Nice 60 foot time. Good luck with the 330 pass.

Plan to make the Shootout.
Still working on the car as needs to be 5.3 in the 1/8 mile to get where I think it can. it's in the 120's but needs to be in the 130's at the 1/8 which will put it at the 170's in the quarter. It's a slow process but because I'm being careful I haven't hurt the motor this year. Items that still have to be worked out.
1. Fuel balance -- almost there.
2. Timing -- Running it safe right now and that is power loss. To what degree is the question? To be safe, add 1 degree at a time.
3. lockup -- The old setup gained 3 tenths in the quarter and 8 MPH by just turning the lockup on in third gear. Will need to get this working before I mess with timing.
4. Power run out off the line -- still playing with how soon you can add full power without traction issues or bending the rearend. About took out a tracks timing boxes last week as it was all over the place and had to get out of it. I think the track was as much to blame as the power.
That list is time consuming. The best way to do things is changing only one item at a time so that's a lot of passes. Trying to speed that up by staying at the 1/8 and only doing 1/4 when all looks good at the 1/8. Less stress on everything by only going to the 1/8 to get to the next change.
So all that is not going to be perfect in three weeks. Will be using the Shootout as a test session to continue where ever I'm at in the list.
Bet it's the only outlaw car with a GM computer, Opti that is still works and basicly a real street car. It's a much slower road but fun when you get it all there.Last edited by Jeff Green; 08-22-2019 at 12:50 PM.
