Re: Eliminate draft tube options
Only if the torque on launch dictates the need. That same motormount setup worked in two ton trucks coming out of fields well overloaded in compound low with engines putting out all the torque they could muster without failures. At least I never heard of them failing. Leaking oil compromising the rubber was normally the reason for failure. At least every one I seen that was bad was oil soaked. That isn't likely to happen on that engine.

Re: Eliminate draft tube options
Considering the quality of new parts these days, anything could happen.

Re: Eliminate draft tube options
It doesn't take much effort or $ to install a chain to keep the engine from torqueing over too much and that is old school tech. You just leave enough slack so that the chain stops it from moving too far but still lets it move normally.

Re: Eliminate draft tube options
With the cable throttle torque reaction of the motor won't pin the throttle open.
Anyone reading this with a solid rod throttle setup: the key safety thing for you is to make sure the link between firewall and engine is angled so that if the motor rises up after a mount brakes the arc of the link moving closes the throttle, not opens. With new mounts I'd just keep an eye on them. Or weld a tab to the cross member to limit how much the motor can twist if RR mount breaks. Or run the ignition wire so it unplugs itself if the motor flops over. That is a very pretty engine bay, a chunk of chain is going to look off. |

Re: Eliminate draft tube options
as for new motor mounts, they don't make'em like they used to...
a short length of cable with pressed on ends and possibly covered with black shrink tube or the like would not be noticed too much under the hood, wouldn't rattle or remove paint etc. it's just a suggestion because I have see and worked with the "new" motor mounts for that truck and thought about how they didn't look as tough as they did in "the old days" and thought about the extra torque your new motor with the supercharger would have. it would be a shame to have something let go and not be ready for it, thats all. like LG says, new mounts, keep an eye on them. |

I like the idea of a cable versus a jangling chain. Could I attach it to the block on the drivers side where the three bolt side motor mount holes on the block already exist? Where on the frame would it be attached? Since this hot rod inspired truck isn't going to have bumpers, there are existing holes in the frame for the bumper bracket bolts. How heavy/gauge of a cable would I need?

Re: Eliminate draft tube options
Obviously the higher up on the engine the better the leverage would be. It also doesn't need to be located at the front.
I think 3/8 cable would be fine with swaged steel ends. Attaching to the web if the frame is best, or a crossmember. Think of where it will achieve the best leverage advantage. |

Re: Eliminate draft tube options
I’d wait until everything is in place and figure it out last. Could save doing it over.

Re: Eliminate draft tube options
Yeah, thats what I'm thinking. The headers and the intake manifold for the supercharger make things a bit challenging. Just this morning I had to modify the spin-on oil filer and associated hoses as the way the builder installed them, they interfered with the rear header section.
