It is possable to get a 400 small block and use the 350 TPI system and get it to run good or do you just recommend the 350?

do a search for this, and u will find all the info u need,

Does anyone know how much a 400 SB gets. What would you predict for a TPI system that has be properly made up to flow for the 400? And what will I need to do to get it to bolt up to a T-56.
-Thanks

You may need a 400 flywheel, since the 400 is externally balanced. That is unless you want to spend some bucks to make it internal, then all your 350 stuff will bolt right up. Off the top of my head, you MAY also need:
- Hi-torque mini starter may be in order depending on the size of flywheel.
- You will need an older style 400 pan w/driver side dipstick. With headers, this is not a problem, with stock manifolds it is, and you may have find a pan with the dipstick tube base welded into the side.
- Custom chip to get full potential

Hey desert roc are you still running the stock tpi setup with that 406.
Where did ya get your chip.
You should try running some of the NMCA efi classes this year. Tell me how it does once you get her set up.
