I've seen several 427's with over 400rwtq by 2000rpm but, I haven't seen any 402's. Are there any out there? Dyno graph please!

Mind you this is thru a sloppy n/a converter, I am 100% sure with a locked converter ora 6 speed it would top 400 tq @ 2000

 

I have a 346 with 405rwtq through my stalled A4..

 

At 2000rpm??

 

Mild build, 11.3:1, L92/L76, 403

380@2200RPM

501/470 peak numbers

 

We did a 402cui for a C6 A6 that made 380rwtq by 2200rpm (start of test) on our Mustang Dyno.

 

No...No..

I am sorry, i mispoke. Mine was @ around 5600... sorry..

buy a dump truck

 

I am very close if not right on:

 

Or a cummins.

 

I saw this on your thread. It look bad azz. Hell, I didn't now you could put ls7 heads on a ls2 block. Or was there something different about your setup?

 

Nothing different just very, very pricey heads. Not even a fancy Fast 90/90 setup. Just the stock LS7 intake mani/throttle body.

 

not really sure what good it would do my 400FTLBS at 3k is hard as hell to hook up. i cant fathom any more.

 

What was its peak numbers?

 

Just imagine if you did get it to hook. Although a little spin is good for the wallet. I'm sure that guy who got his car done at Straightline with 380rwtq by 2200rpm is very pleased with his car. Better to have it and not need it, than need it and not have it! I'm just trying to find out whats the most that can be had that early. Anything over 350rwtq by 2000rpm is plenty.

 

350ft lb by 2100,380 by 2600,400 by 3000.

474rwhp/474rwtq.

We had the car at the Chicago Chevy Vettefest at McCormick Place this past Feburary. It's definitely a fun car. I've never seen a stock converter, stock gear (2.56:1 for the A6) car with 19" Budnicks do burnout well into third gear.

 

surely there's gotta be more out there!

 

Does this count?

We just completed another 402 in a 2002 SS. Pump gas motor, G5x3, ported 241 casting heads, and a FAST 90/90 set up, 3.73:1 gear, RPM Stage IV 4L60E, Yank 3600rpm TC, Kooks 1 7/8 x 2 x 3.5" Stepped headers. Final numbers were 460rwhp/440rwtq on our Mustang Dyno(heads really hurthing this motor). It had 380rwtq at 2500rpm, 415rwtq at 3000rpm. Can't wait to get the bottle on this one. Maybe talk to the customer into putting some nice ETP or TF's on her too over the winter.
