I am building a Gen4 454 .40 over with rectangle head 8.1 compression. I am using a 177 blower. my questions are what size fuel pumps should I use?
Can I use a DUI distributor with rev limiter instead of the MDS wiring mess?
What size oil pans should I use?

Thanks for the time fellas!
You ant drunk until you **** your paints!

Run a fuel pump in the 140gph range. Use 8 quart pans at a minimum, 10qt would be better.

Tyler Crockett put together a great package like this for me.. You might contact him for a carburetor. He had one built from Quick Fuel that I put on and it literally felt like EFI. I didn't even have to adjust the idle. Quick Fuel is here in Bowling Green. They actually run each carb on a motor before it is shipped. The motor combination is a sweet package. The 454 with the supercharger works well. Eddie Young could also help you out with parts. I would call someone like him and get the right parts for your project. He'll give you a good price and you'll get the right parts and good advice.

the dui dist will work fine, limit or lock the advance I ran a 489 setup like this used a H/P hollet elec, no issues, make sure the cam is a good blower profile to get the most out of it
