Hi all, I asked this question over on the OHC site the other day & got a response from Sprint6.
Was wondering if anyone here has tried this ?

The engine ( 250 OHC6 Sprint ) & trans. (TH350) are done. ( RAD did an outstanding job on the engine ! )
I was wondering if anyone has tried to install them as a set ( like a V8 ) ?
I make up a foam board profile mockup & in theory they can go in as a unit if you get the rear end up in the air a bit. 
Just thought I would give a shout out to see if anyone else has attempted ( with success ) this maneuver ?

Thanks,

Wayne

I removed my OHC6 with 3 speed manual all together. I inserted a 350 SBC with a 4 speed all together. I highly recommend an load leveler so you can easily change the level of the engine.
