    It was a case of time and a blown budget really. Just had to screw it together and get it running. Yes 6 inch Chev rods. Scat 355 crank. Add Mallory? I would the piston/rod combination would be lighter than spike rods and acl flat tops? I donít know. Thing is it was smooth as silk with stock mounts. Do they hide a unbalanced motor? The right mount had split in half as well. Maybe Iím just being paranoid as I havenít experienced so called NVH. Who knows.

    The job of a rubber mount is to isolate vibrations while holding the engine in place. A Tuff Mount by design is more rigid and wonít be as effective at isolating vibrations. Itís similar to what you get when you replace your factory rubber suspension bushes with poly bushes.

    Using poly engine mounts I'd keep trans mount rubber to allow some movement...but for streetcar would prefer engine mounts softer,can't remember if tuff mounts available in softer poly or can drill them for some play.

    My vh had 5-8 mm clearance between pacemaker & early powersteer rack...at idle or any throttle it was hard up against the rack.

    The Idle & car shake was weirdly smooth for f280 cam.

    Under hard throttle car would pull to right...switched to manual rack for steering/exhaust clearance the car behaved itself & engine idle was lumpy asf

    Old skool blokes used to do bolt through engine to stop it tearing apart.

    Yeah just read about the bolt trick. Wouldíve been a good option. Originals mounts the pipes were hitting the rack. Could feel it buzzing through the floor and wheel. I have about 5-10mm clearance now and the motor isnít going anywhere with these mounts. Watched some vids with solid and poly mount vibration. Mine is no where near what some seem to think is normal.
    Iíll just keep an eye on my oil filter for signs of bearing wear.
