TSP Level 2A-R (Larry's motor) Complete and Dyno tested.

Larry's car is 4000lbs, the gold car is just over 3900lbs, it scaled in at 3825ilbs with a empty tank so add 3/4 of a tank of fuel to the stock tank and it should put it above 3900lbs, that is less then 100lbs differents. The gold car is a fully lic street car. Larry's car has almost the exact same suspension other then Larry has the addition of no hops in the rear with a better shock then the gold car. The front end is the same other then Larry has a better shock but the gold car has better springs.

At a good track with good air that gold car will go from the 10.80 posted at the air port down to a high 10.60 to a low 10.70 range, that was the first time to a 1/4 mile with that combo.

Here are the stats on the gold car from 2010 when it had cast iron heads,bigger cam then the new engine, it had the same compression as the new engine but a few less cubes.
I copied this from the thread from 2010 as follows:
I sold this car to a buddy of mine back in the early to mid 90's and he final took over to the main land to see how it goes. Its a street driven 70GS455 with a pump gas stage1 462. The car weighs in at 3860lbs and was very consistent. The first video it did a 1.50 60ft, and went 11.11@118.43
it ran 11.11-11.16 all weekend.

Look in my signature below at the GSX clone with bone stock suspension with a anti roll bar, 3.73's, 9.3:1 that ran 11.0's and this car dyno'd 439.39 RWHP/437.99 TQ

Tom Hearsey's street car, over 4100lbs, 10.0:1, small flat tappet, 15X7 ralleys, 3.42 gear, and went 11.4's

You are down on the use of tried/tested and proven speed calculators that are using the exact same math that was used to correct Larry's engine from 533hp to 602hp.

These 2 engine's, my buddy's and Larry's are so close spec wise its scarey, basically the only differents is Larry has 10.5:1 vs 10.70:1 and Larry has a roller cam vs the flat tappet. The gold car has a girdle so he can step up later.

Larry has some basic things to change that will make the car go faster and he knows what they are, and he also knows that I am here to give any help needed.

At the end of the day we don't race dyno's or flow benches the real proof is in the pudding when the rubber meets the road at the 1/4 mile.

By no means am I knocking your work or Larry's car. You have built a great stove for Larry that should stay together for a long time and give Larry much enjoyment for years to come. Hell Larrys wheels were turning before he even left Cecil :laugh: We all know that there is more in this combo.

Jim I respect you and what you do and I am happy that we can have these respectful exchanges, I don't want anyone to think I am picking on Larry all I am doing is busting in Balls. On your car. is that a fiberglass hood? I want my buddy to put a fiber glass bolt on hood on the gold car with a stage 2 scoop but that old snorkel hood scoop must of gained you a couple tenths?

 

I cant take it any longer! I'd really like to see that car pickup .8 and 5 mph from a converter and shifting 400 rpm higher :laugh:. Unless the one in it now is a total piece of ****, its not happening. A converter isn't going to make 1 more single horsepower. 200 posts and 15k view about 1 guys car. If it was anybody else it would be down the list in one day.

OMG! :laugh::laugh: :gp: You are heart less, you are luck Larry is so good natured :laugh:

 

I hope so!

 

Island Drag way was shut down and lost forever last I heard :ball:

 

1989, Fastest GS driven to the GS Nationals, 11.96 and won it's class, 540 miles driven each way. Driven/owned by "NormsGS".

 

I thought the video was going to be your car when you drove it a good distance to the track a few weeks back and ran in the 11's and then drove it home

 

Nah! I guess I didn't think it was that big of a deal! :bla:

 

I guess all I'm saying is that it really isn't rocket science to put a full weight skylark into the mid-hi 11 sec range. My 72 was a full weight car with a B4B, Qjet, 3.42 rear, Ebrock ported aluminums, 226/239 Scott Brown hydraulic cam, headers and an old KB 3500 converter. 11.80's all day. Granted, 11.80@112 isnt 11.50@116 but still its a pretty simple relatively low buck combo. Good luck Larry, you have a nice car.:beers2:

 

I won't kid you it's a bit loose but not unmanageable. I don't own the car anymore, I sold it. I think with 3.73's I could have improved the et a bit but it wouldn't trap any faster. I was lucky to have some of the best advice available from some of my Detroit pals. When I bought the car three years ago, I didn't even know what a stage 1 fuel pump was. I did have a lot of experience with turbo bucks though.

 

Big block cars wont hook with a 26in tire on most tracks not enough roll out not on a max power launch anyway

 

How about 21 years ago :laugh: I had to dig but it gave me a chance to go through all my gsxtra's May/June 1992. Same weight as Larrys and a 100 lbs heavier then the gold car. They were all heavy back then. Neat to go back and re read these, where has the time goneo No:

 

It could be a timing problem holding you back...

There's a really good thread on here about power timing:Smarty:

Maybe you should check it out.
