Re: stock l98 (BowTieBlood)
I thought those figures were interesting, so I pulled out a Road & Track Comparison from March 1986, here's what they said...
BHP............230@4000
Torque........330@3200
1/4 mile.......14.4 @ 96.0
Top speed....154
Test Weight..3450
Final Drive.....3.07
(all with Z51 coupe & 4+3)

Re: (scorp508)
I'm goint to print that out (Scorp torque curve) as that is exactly what I want - a torque curve that peaks early and then falls off. But I know Scorp has the '87 with a different [roller] cam than mine, so I'm going to have to see what I need to do to get that cam to work in mine...
I'm aiming for a "falling torque" curve.
(There was an interesting column in Cycle World a few months back on using "falling torque" as a traction device.)

Re: (Rich B.)
Using a roller cam in a non roller block is expensive, and a huge waste of money for what you're trying to accomplish. Roller cams are great because you can slam the valves open, keep them open, then slam them shut. But... GM didn't have that figured out when they made the L98 cams. That cam is only worth 5hp max over your cam, and it's going to cost you nearly $800+ to retro that cam into your car.

Well, what I have isn't all bad, but I don't have a curve to look at...Maybe R&T does; have to look...
Thanks for the reality check! :lol:

Re: (Rich B.)
I ran a 13.9 @ 102 with the G-Tech. I don't know how accurate G-Tech is but that was on a road with a slight curve in it. I shifted at about 3500 rpms.I only have a few small mods and my engine has 150,000 miles and 2.59 gears. :U

Oh I guess I forgot that ET part.
The car ran 13.89 @ 98.17 in stock trim with a small amount of wheel hop. In "lightly modded" trim she's done 13.48 @ 101.11 so far. I think thats the best you'll see from her like that because I think I'm finally pulling the heads/cam this week.
