SBB sheetmetal intake and more… by 87GN@Tahoe

So to mount the 90mm TB, I had to machine an adapter plate, as the bolt pattern was different from the ford bolt pattern originally machined into the front plate of the plenum.

Here is the piece I machined out of 1/2" aluminium plate with countersunk holes for mounting to plenum. I also machined grooves for 4" rubber o-rings front and back in case I decide to go that route for sealing:

Mounted to the intake:

VROOM VROOM!

Now I can run either style of throttlebody with just the turn of an allen key

You and I may be more alike than you think

I see you went to Drag Week.. I would like to do that as well in the future with this car. How was it? your likes/dislikes? Adivice?

On another note;

I have a bit of a conundrum at the moment... I have a new, reproduction fuel tank (for a '65 Chevelle wagon) and am debating whether I should put an external sump on it and run my A1000 externally, OR cut it open and put an internal sump/baffles and run the pump internally.

External benefits are ease of maintenance/ repair with both filters and pump our of the tank in case of obstruction or failure. Downsides are louder, more obvious (less and less a "sleeper"), potential for it to be scraped off the tank on a (waaayy in the future) wheels-up launch or by road debris, pump running hotter/not lasting as long.

Internal benefits are quieter operation, cooler/lasting longer, more of a "sleeper", wont get scraped off. Downsides are Murphy is always lurking and with my luck he'll wait 'till I just filled the tank for there to be a clogged pre-filter or dead pump. Also making an effective internal "sump" that would still allow for most of the fuel to be picked up could be tricky...

Anyone with any ideas/suggestions/pictures???
