351 mod question

[351mod_stang]

Hey i'm rebuilding a 351mod motor right now and was wondering if anyone had happen to rebuild one before? Does anyone was also know what manual transmissions would hook up to the back of it?

This guys a friend of mine... hes picked up a 351 Modified and is wanting to drop it into a notch. Anyone know if it uses a BB bellhousing? or SB?

any manual with a small block bell housing pattern, T5 would even work, but you would prally break it in a day or so lol. dont forget your gonna want a new hood, motor mounts, oilpan and headers for it to fit in that notch.

thats what i was thinking.
Thanks man!

not a problem, a 351 based stroker was gonna go into my 88, then i just decided to part it out and buy my 90 which is staying stock motored for awhile.

A 351W has a diffferent balance then a 5.0 the 5.0 H.O. has a 50oz harmonic balance and flywheel you will need a flywheel; remember most trucks had 164 thooth and the cars had a 157 tooth. So you will need to buy a 28.8 oz harmonic balance and a 28.8 oz 157 tooth flywheel.

If its a 351M, like out of a truck or big car, its a big block bellhousing pattern. Which is why its an M.

If it is a 351M, I hear they also make really good boat anchors...

But yeah... it is a destroked version of the 400, which used a big block bellhousing pattern, mainly for compatibility with the C6 transmissions. Check out this link for a lot of info on the 351M/400.

I'm still running a t5

granted it grinds third all the time and intermittently locks itself out of second

but hey it still works.
