I was also thinking that might be of help, now to find some heat lamps.

60-100 watt regular bulbs under the pan do a pretty good job too. Some foil wrap to help direct heat and confine it to block area should help too.

Ooops... are regular old bulbs contraband there???

They've been slowly phasing out the old incandescent bulbs here, but I do have a few new 100W bulbs stashed away that I can use.

I haven't had much time lately to mess with the 389, but I did pick up an interesting piece of the puzzle today.

A 1959 Tri-Power cast iron thermostat housing was generously donated to the project by PY member 56 Batwing. Thanks again Jack.

What makes this part unusual is the engine lifting loop built into it. On the '59 2 barrel and 4-barrel intakes the loop is integrated into the intake manifold casting, but for the Tri-Power they were only able to find room for the loop on the thermostat housing.







Here it is shown next to an aluminum repro of a '65 Tri-Power housing for comparison. The '59 unit is pretty big and heavy, I put it on a shipping scale and it weighs 2.85 pounds compared to the '65 aluminum repro at a scant .55 pounds.



Here you can see how the lifting loop configuration of the thermostat housing was copied in .150" to .175" thick stamped steel for later engines, attaching to one of the studs that mount the timing cover.

.....along with the correct linkage and fuel lines, sitting on the builder's workbench ready for shipment. The carbs, linkage and fuel lines are shown here mocked up on a 1960 intake.

Pretty unusual fuel line routing compared to what I'm used to seeing on the more common '64 -'66 setups.

New toys.
