i went to the swap meet this morning at vets in lb, and bought an HEI distributor for my BBF...come home, go to drop it in, and it hits my tunnelram and doesnt have enough room to go all the way down!...so i guess i cant use a big distributor w/ a tunnelram? do i have to get the smaller one now? are there any HEI small distributors out there? i wish i knew this before...

Which
brand HEI dizzy? On some, you can remove the large cap AND large diameter cap bass, then install the small cap directly onto the distributor housing.
If you can't do this, then my adivce is to get a FoMoCo Dura-Spark distributor and recurve it. Best deal electronic Ford dizzy out there for most 460 engine builds. Where do you think MSD get's their reluctor and magnetic pickup coil?

Dizzy and box can be had for about $50 at a yard, then the recurve kit is $10.
