WhichBlock should i use for a performance build 1966 or 1978

Frankenstang,

I think you are right. Bruce told me that it will be a shatter proof bh's and that it will be 12lbs heavier than the aluminum bell.

What years and in what cars did that (stock aluminum 'holy grail' bellhousing with the Clutch Cable provision) come in?

Did they also come in the cars with 250 motors or just the 200's. Thanks.

Hey JMB, well as far as I can gather from some old posts here the bellhousing could most likely be found on an '81 Mustang or Capri with a four speed, non-overdrive manual transmission (T-4...EDIT: Not an SROD), and the casting number is E1ZR-6394-AA.
Here are the posts I have bookmarked discussing the 'holy grail'.

This is a picture of the HTF bh:

And you can also find some discussion of them on these two pages with side by side pics of the SROD & T-4/T-5 bell:

EDIT 2: Obviously the best things about the 'holy grail' bh or the one Bruce is talking about producing is that it would do away with the need for an adapter/spacer plate (correct length bh w/t-5 pattern) and have a cable clutch provision. Then it's just a matter of how much would someone be willing to pay for it

The 250 can use a sbf bellhousing AFAIK, so if you plan to use a 250 at some point, a cable bell is a relatively easy mod...but I don't believe there is any crossover on 200 & 250 bh's.
Hope that helps. There is also a brand new post in the tranny section where a member modified an SROD cable bell to take a T-5...I don't know what's more impressive, his work or the equipment

Be aware that the '78 motor is low compression. You'll probably want to zero-deck the block and/or the head to get a respectable compression ratio. If you have both motors side by side, measure the piston crown height and piston dish.

Frankenstang,

Thanks again for the info.

Bruce said his bell will be around $400-450 and is expecting it to be ready January or Feb.
