Default Top speed...

Has anyone tested top speeds on big cubed (422, 427, 434) LS1's?

I did some theoretical computer tests with my cars configuration to see what the top speed might be.

It doesn't matter if you have a big cubed motor, because it all comes down to RWHP. If you have an F-body with an average weight, with a 6 speed, and 4.10 gears that is pushing 500 RWHP or more, you can use the 5th and 6th gear as a power gear to acheive a little over 200 MPH. Right around 215 or so.

But, that is just using the standard drag coefficent for a camaro, and then adding in the weight and my RWHP per 500 RPM until I reach my peak power in 6th gear at 6700 RPM.

Hope that helps.

That post is too long for me to read.. Both cars are nice.. Both cars are fast. If it is top speed I am going to say Camaro. When I had just cam and headers with 3.42's I was 3 cars in front of my buddy and still going upwards in the rpm band. My RPM needle in 5th read 6250 and was still going until I ran out of road.. You do the math..
