after spending the past few months with my mark, I can say for certain that my lsc "just" keeps up with every modern 4 door sedan...hell I tied a mid 90's 4 door accord with a fart pipe the other day. These mark's are downright pigs....way to heavy for any useful speed, unfortunately. It's really got me pissed to the point where even my planned 4.10 gear swap is wortheless.
I don't see a Mark getting beat by a mid 90's Accord, but I guess anything's possible. For a short time I had a 94 Accord 4 door built for street racing that I got off a buddy of mine. It had a JDM H22A (2.2 DOHC VTEC; one of the more high performance Honda engines) with Skunk2 stage II cams, flat-top pistons, full 3" exhaust, LSD automatic transaxle, and I don't remember what all else, and it still didn't have the power, acceleration, or top end of my Mark. I ended up selling it to another friend who swapped a 5-speed into it and I EASILY beat him in my parents' stock 96 LSC, which was noticeably slower than my 93.
As far as trying to say what's going to beat what on the street, from my experience, it doesn't matter so much what the numbers say. You can look at hp numbers, torque numbers, weight, 1/4 miles times, 1/8 mile times, etc., but I've seen plenty of people who "won" on paper lose on the street, and I did alot of that in my Mark VIII. I would race people who should have easily handed me my ass and beat them, or in one case, BARELY lost. Don't let people telling you you're going to lose based on the numbers get in your head. Just get out there, drive it like you stole it, and see how things play out. You might be surprised. One example is the one race I barely lost: it was me in my basically stock Mark VIII (see my sig. My car was hardly what I'd consider "built" by any means) vs. an early to mid 2000's Honda S2000 5-speed or 6-speed (whatever they are) with a full exhaust system and a good tune (Hondata I believe, if I remember correctly). We started from a dig, and naturally, being a manual transmission, he jumped ahead from the launch to where his rear bumper was even with my front fender, but we ran all the way to 100 MPH and we stayed like that the whole time. I couldn't pull ahead and he couldn't pull away from me. We probably would've taken it farther than 100 MPH, but we were on a 2-lane country road in the middle of nowhere and coming up on a sharp curve so we had to get out of it, but that was the closest race I've ever run. That's the same reason I never put money on a race even if it looks like a sure thing, because you just never know what can happen out there.
