Big Block Bellhousing Crossmember for manual transmission
 
Does one exist specifically for big blocks?

I think the bellhousing for a big block could be machined differently, anyone have a known big block bellhousing for pictures?

I swapped out the 350 for a 454 and it bolted up perfect. Don't know if original bbc trucks are different but SBC works without any issues. I even used same bell housing for my m21 swap. If u needing one I have an extra that I don't need.

If you are giving it away no problem, but you can't sell parts on here unless you are a paying member and your name is in Blue. Click on the word "Subscribe" in the menu bar above and it will list the different subscription options.

Thanks.

Yes. The big block manual trans crossmember exists, and it is different. Not near as many big block manual trucks as small blocks so they can be hard to find. Not sure what all the additional parts you need are, but clutch pushrod from pedal to z bar, z bar, fram bracket etc. are all different if I remember correctly. High hump floor has different location for shifter hole as well.

I looked for a long time to find all these parts when I was going to convert my 70 Sierra Grande to manual.

I find your post to be very credible. I never considered the floor hi,p being different but I now know it would also be different since the trans sits a little further back with a big block. Thank you for the information
