The link i posted to summit has the part you need,
on the 85 the left side (drivers side) is the auxillary fan,
on the right side is the primary fan,
I know this 195 f switch works, when we had the snapon reader hooked up to the ecm doing the timing the primary fan came on as soon as the temp hit 195

sounds like you are going thru the same stuff i did ! When i put the edelbrock heads on i had a larger hole too, I went to the industrial fittings place and they had adaptors for everything, so check the phone book or google,
and yes i wondered the same thing about the temp switch being away from the water flow, but it seems to work fine !

Notwithstanding differences in fan operation.
84 had a mech switch only for the main fan
85 had ECM control of the fan and mech switch for aux fan ( if fitted)
And supposedly a mech over ride switch for the main fan
86- 89 had ECM control and mech switch for aux fan ( if fitted)
90+ had ECM control of both fans

I was unaware of that ! TY for the clarification.
To the above "big hole small thread" problem...go to ACE hardware or even the Depot and buy the appropiate brass bushing. That allows the sensor to still enter the block the same distance...it simply fills the hole. Even IF the sensor were OUT of the hole 1".....its still going to be submerged in the hot water...won;t effect anything. The water under pressure will find and fill the voids.
I guess the easy way for those that understand the system operation would be to simply ground the sensor wire to ground and see what happens....something will come on or the gauge will go to a default setting.

Okay I got the reducer and I am progressing nicely as I have stopped at intake manifold issues. The bolts that I ordered came in snapped at 35lbs torque at the first bolt. Second one snapped the head off, so I see it's grade five bolts. I wonder if it's a wrong grade and I should try to get higher grade bolts? Thanks
you dont need that much tension (or a high tensile bolt) on alloy manifold onto alloy heads, you are better off doing them up hand tight with a ring spanner (or a wrench if you live in usa
)its the tightening sequence that is probably more important.

35lbs is what is recommended for iron heads, do you now have alloy heads on your crate motor ?

it's just a motor and the tranny stayed in there as pulled the motor.

Leave dist out , get 2 bolts 2 or 3" long, cut the heads off and install either side in back of block
Lower into car , line up bolts with trans
Push engine back onto trans and set onto engine mounts at same time.Some jiggling required
Helps to have a jack under trans so you can adjust height to suit

C4 cooling problem
After a short layup, my cooling fan no longer turns on. Questions are: there are 2 fans which is the primary? What signals the fan to come on? Of the 2 grey relays on the drivers side mounted next to the radiator, which controls which fan. Also when I turn on the AC, the AC clutch does not activate nor the cooling fan.
