I gotta admit this thread embarasses me...
My old Dodge Stratus board used to have discussions like this all the time - "Will my 3.0 Stratus with CAI beat a stock Accord?" They got so monotonous...
But since this is the first I've seen on this board, I'll give it a go!
I think you're gonna get beat. I think it'll be close, but I think he's gonna get ya.
I street-raced one once in my Stratus - 3.0, V6, 5speed. (For what it's worth, I've run a 15.1 in it) and he walked me pretty good right off the line. I couldn't run with him very far - had to pull off onto a side-street. My Stratus whoops the crap outta my Barracuda, and I know my dad's 340 was quick, but isn't wasn't THAT much quicker... I dunno. I say it'll be close. I DO know that if he beats you, you aren't ever going to live it down.
...and you'll be shopping for a 440 like I am.
