I was wondering...how high can a Series 1 L67 reach without exotic mods? Like without turbocharging, nitrous, or fabbing up Series II heads :P . And without crazy amounts of capital

I remember hearing something about someone hitting 13s with nitrous...

One word "zilla"

Well Mr. Wren holds the title for fastest Series I without the juice. 14.665 @ 92.64, and I don't even know how recent that is.

Perhaps he can shed some HP numbers on the situation.

This summer recent. I saw it, hell i could of been ******* blind and still of known it was his car going down the track, even heard it clear as day over Schads Straight piped 00 SSEi.
Yah, it pulls hard

The 14.6 is decieving. I know it sounds like the typical excuse, but I could NOT get traction off the line, and BROKE traction on an NHRA dragstrip prepped for 600' when I hit second gear every time. Many members here were there to witness it, as Matt mentions above.

Had I been able to hold traction, the numbers would have been a bit different.

I have no aftermarket hard parts on my car, and I've never changed anything in my valvetrain, but I don't know the actual numbers for hp or tq at this point. But more is coming this winter.

I would guess a 94 L67 could easily reach 280+hp without MAJOR engine work. But that'* just a quick estimation not based on personal experience.

Breaking free when shifting to 2nd

The video is posted. But remember, a Series 1 is alot more likely to be able to do that than a Series 2, simply because the torque peak is developed at a much lower RPM.

Someone find the link for him.

bahh to lazy, however, its pretty insane.
The shift kit helps alot though to..
WE need to dyno your car Bill, to know for sure.
What is your CURRENT crank HP guestimate?
