My car dyno'd 231/270 stock. with a misfire. and bad o2. ran smooth, but wouldn't have picked up much if running optimal. So your minimal mods on my car wouldn't have netted anywhere near what you want.

Hence the range I gave you. Don't expect to be on the high end. Expect low and be happier. Dyno's are a let down for these cars anyway.

If it actually ran good, I would expect 280ish rwhp and 310ish rwtq. It seems not many LT1s run right these days however so be happy as long as it doesn't puke rods all over the dyno.

So you think he can dyno 14whp more than you with slightly better exhaust and stock rockers?

When I first got my car I was into the "dyno" and wanted to dyno it
Take it to the track and run it thats the real dyno.

Cool your car dyno's at 500 HP but you run 12's
Man thats reallllllllllll Cool!!!!!

Take the A4 with 4:10's out to the track should be pretty fun

You could get away with Nitto DRs or their other soft compounds (NT01/5)

1/4 with some stickys Id say you'd be damn close to 12's

and BOOOOO on the Nittos everyone who has them it seems to be 50/50 if you hook just order some ET radials from Mickey Thompson I think the Nittos were 340 to the MT being 400 and if you take them off and only use them for the track they will last a longggggg time and be more consistent.

But yeah man I'd say realllly close to 12's with a good DR
and is it tuned?
