Instal a 250: p/u tube changes needed

Lookadat length!
So for the 250 swap in to a Bronco:
2 rear sump 200s anyway - War Pony's in a 1). 73/4 bronk (200) and then the 2). FOX bodies…
3). One in a 170 (frm another bronk '66 - '72)…

I was tryin to figure how to bend the tube…if I could just buy THAT one, mayB make/buy the lill mounting tab… :hmmm:
How duz dat wrk OE? It looks like: a stud w/a bolt, the tab, nother bolt on onea the main caps? P/u's still a 1/4 - 1/8 inch off the bottom of the pan.

What years were the 200 in the Fox bodies? '79 - 83? They had 250 as well in those yrs? (called 'stang & Capri?) The 250 must have been a rear sump too…


More on stock parts to "bronco up a 250" from another thread somewhere here (non-bronk forum w/a pic).
Could get the pick up and tube from the above - still workin on a stock pan, continue to like the "braze up two pans" method…

Hey Chad,

A couple thoughts for you on this.

1) I used the stock 250 pan and cut the pumpkin side to be smaller. See my build thread if you want to consider that option.

2) I ended up putting a set of these on my truck. Really Big Bump Stops. Even without my mod to my pan, I'd never hit with these. This is the easiest solution!

3) You should make sure the pick up height is right before you seal it up. I would loose pressure sometimes at high rpm. It was due to the pick up being about 2 inches up. All the info I saw said the pick up should be 3/8' to 1/2' from the bottom of the pan. I was able to heat and bend the pick up tube to get it to where I needed.

Hope this helps.

-Jimmy

It's been a while, but when I looked at using the 170 p/u on the 250 it didn't look good.

I found a few posts by machine shops and engine builders that mentioned the 3/8" to 1/2".

Here's one example: http://www.chevytalk.org/fusionbb/showtopic.php?tid/116996/

Thanks for the pointers,
every idea accepted.

[quoteMy hope is to use the 170 prts (C earlier post).…[/quote]
bottom 3/4 of 170 pan
a 200 ci tube/screen
'80/83 200 rear sump
etc

not wanting to heat/bend tube or go w/o that lill tab to 3rd cap bolt

Again - lotta things R decided 'when U get there' and appreciate the help planning so
'gettin past there' can B done more successfully. 'Mix'n match' seems about right -

All good. I just was trying to pass along stuff I recall. All kinds of ways to do this. After my pickup height issues, I just wanted to chime in so you didn't have the same problems.

Good luck to ya.
