your 383 setup?
your 383 setup? I am looking at doing a 383 stroker potentially in my porsche 944 but I need a few pieces of data. I am especially curious as to MPG since I've heard it isn't effected much by stroke.
1.MPG before and after stroked.
2.What your current setup is.
3.What are your dyno numbers tq/hp before and after. (1/4 mile or 0-60 could also work)
4. Have you autocrossed or road raced your car and is a 383 a good choice for a road car?

I talked to texas speed and they said it would be a good setup for autocross/road racing. They seem like a very knowledgeable shop. They estimated a mild cam with a 383 setup would stick me at about 25mpg in a corvette on the highway but this was all ballpark.
Anyone have straight data?

MPG info I haven't run across but interms of everything else you want there is a ton of info on this board. Just do a search for 383. I have a block I am planning on building a 383 out of as well. It's a pretty popular and affordable setup.
MPG is dictated mostly by aerodynamics and drivetrain efficiency, with vehicle weight playing a roll in city from accelerating the weight. That said displacement and HP don't have a big effect, even deeper gearing usually isn't a big deal.
The constant is still the work the engine needs to do to push the car through the air.

Car was never setup to be a drag car so times could have been better but it didn't interest me that much.
