1970 GTO Version 2.0

[406 Q-ship]

Andrew, It ran a 12.7 without a tune and a 2.1 60' that is more than pretty good, considering what it will probably knock down in the mileage and fun to the mile.

Great build and nice wrie up. I have the same M/C and will be running manual brakes. Glad to here its working. Thats also great info about the driveline angles.

Very cool. What did it run with the previous engine?

Once the shaker is working and the rest of the intake is finalized, I will get it tuned. It's pretty fat at WOT right now. So between a tune and the cold air from the shaker I bet it will pick up 15-20rwhp.

My best times with the 502 were during Real Street Eliminator. I ran 12.1x consistantly @ 114-115 mph. That was on a small set of ET Streets, getting 1.8x 60 foot times.

Dude, did you take it to Bowling Green, KY Beech Bend? That is where I always go! That is only about 2 hours away from my house. I would love to get up with you over there and check out your car.

Let me know the next time you are heading this way. I would be happy to hang out at the track.

I just had it chassis dynoed today. Anyone making guesses?

Sweet. I'd love to have my car in the 12's. That be more than enough power for what I want to do.

I'm so glad you are build this L92!
I'm learning a lot!

I was going to keep the truck intake and VVT w the hopes of putting on a Magnuson in the coming years, but it looks like 500 crank horsepower is reachable w your mod formula and a tune.
tough to pass that up!

You are the man Andrew!

I was even looking at my Buick today thinking about going manual brakes.... I'm such a follower!

No leg humping allowed. I am just a car geek like everyone else here.

If you do my setup, just get a Magnuson kit for a Corvette down the road.

The man said he would get 420 horsepower to the wheels and he wasn't lying. Good numbers Andrew. I have a feeling that little mill has more to give up once it's plugged in at the tuner.

That engine bay looks the perfect size for an LS7 engine ;)

Very good to see the GTO getting some lovin again..

An LS7 would be nice, but I really don't see the need for all the dry sump stuff. This engine is making 90% of the power of an LS7 at half the cost.

Ca-Ching!! Excellent results

[trapin]

I have never understood people's infatuation with the LS7. Have you seen the size of the tank for the dry sump system? It's more trouble than it's worth to try and package that thing in there somewhere. Like trying to hide a mini air compressor in your car...and for what? There really isn't any REAL power or functional advantage over the engine that Rupp has in his car or that Andrew has in his. All 3 engines will do the same job.

I agree,I'm just buttoning up my 6.0 L92 engine for my 68 Camaro,if you shop around,you can made 500 hp for less the $3500,and if you break something while pushing her beyond her limits,you don't want to put a gun in your mouth like you would if you bought an LS7.Ron

Bang for the buck, others surpass it but...

IMO I think a big part is the cachet it carries from the factory it is a 427/ 500+hp motor plus its got the goodies like JP mentioned.

A lot of us like to build and sell soon after so obviously it helps resale values also.

I'm seriously considering one for all the above reasons to stick in a '55 Chevy.

I can, in one word: titanium. As in connecting rods. At least that's what I find so compelling about the LS7.
