what are you talking about, its surprising that the roush even kept up

good call on the "twin screw" too

What are you talking about? 62cc chambers? Stock LS1 heads are 66.xx CC's...

Heads, cam AND intake with a GREAT tune and GREAT engine to hit 405rwhp?

With just those two comments you've shown you know JACK **** about the LS1 platform and all LSX platforms for that matter.

As was said before, the 427R was lucky to even stay as close as he did and if the race were to be extended into 3rd gear and on, the OP would have probably pulled bus lengths. You're talking about a car that has the ability to trap 108-110 to a car that has the ability to trap 115-116.

The two post above mine (including one from a Mustang guy) have already educated you enough so I'm not going to go into your entire post, but I guarantee from a 60 roll it would have been VERY bad for the Roush. I started pulling him in second and really started to walk him once I nailed third. I let off around 90 because I was still in city limits and I had proven my point. If we would have gone 60-120 I think me putting at least a car and a half on him would not be surprising at all. I've done a little reaserch on these cars and they look to be a high 12 second car at best.

Brilliant just brilliant. The two links below will assist in your much needed education of LS engines.

good kill

I saw one at OSW Friday night and it was obvious the guy couldn't drive as he was running 14's Was a great looking car though. There was a poor bastard in a C5 Z06 that was mean as hell sounding that was stuck in the 13's too..

I didn't read the whole thing, but I just wanted to say that from a dig on the street I took a "427R" two out of three times from a dig with only headers and a lid. Both of us were shifting. Pretty close all three times.

I thought they were 427 cid's at the time and thought the dude was just a worthless driver (or was shifting too low in RPMs). Seems I was only right about one of my asumptions.

Here you go buddy, I went and found a few for you.

Here’s one:

Here’s a cammed/bolt-on/tuned 6spd with a built drive train (12bolt, gears, built tranny etc.) putting down 413rwhp and then with just the addition of STOCK LS6 heads, he puts down 440rwhp:

Where is "around here"? You should be more careful with the Saleens. They are a little different than the Roush stangs. If you're stock an S281 will be no problem, but watch for the S281SC and especially the S281E.

Do you have any idea of what youre talking about?
A 405rwhp car beat a 360 +/- rwhp car.

Many bolt-on/cammed LS1's hit 360-420 rwhp.
More then enough to take down a stock 427R.

Good kill to the OP.
I have seen a couple of those cars in life and they are sharp cars.
I like the way the Saleen's look to.

I'm on the west coast. I'm not overly concerned with any of them. The worst that will happen is I'll get beat and if you race and aren't prepared for that you shouldn't be racing. I doubt it will happen but it could.

It's not fast and I never said it was. I just stated that I'm not too worried about getting beat by a Saleen. If I do O-well I got to have fun and hopefully the guy in the Saleen does too. Same thing I said before maybe this wording is a little better though.

I'm jetted for a 150 shot, but have yet to spray anywhere but the dyno. I'm having issues with my window switch and I just got my car back from the tuner late Friday night so I haven't had time to even mess with it.

I didn't mean it to sound like that.
Just saying that they're not worth the money people pay for them.
