i'm wondering if i will have any cooling problems with my 318 now that i put a 340 intake/4bbl car on. i didnt know until i took it all apart, but my dad wasnt running a thermostat when it was stock!

the only time the temp gauge would climb was when it was sitting in traffic in the summer heat.

when i put her all back together, i threw in a 180* thermostat, but the car doesnt have a shroud, which i'm told makes a big difference in the cooling efficiency. i didnt get a chance to take it out on the road yet cause i'm still trying to get her to idle right, but should i have any problems without a shroud?

thanks

I'd say try it like it is because you can always add a shroud later if you find you need it.

should do fine for test and tune,what kind of fan set up does it have?

what intake and 4-v carb?

just bumping to a 4-v should not change any thing unless it way lean or timeing out of whack

what condition is the rad in ?

run it till you find a stock shroud for it,I have done that many times

Lots of BBs and SBs never had a shroud.My 65 BB never had one till I put a C body rad in it.Rocky

The shroud was not stock on the 318 engine unless you spec max cooling such as 318 trk or van on the cars no unless again Max cooling with A/C. The baby rad maybe a problem if so get a rad with 22-26 inch core. I know a guy who has a alum rad and custom shroud that should fit as it was in 71 Cuda and price was reasonable and looks new

73 Challenger 318...no shroud.

There is nothing wrong with using the Lokar kick down cable.

There is only three for Mopars Stainless or black for a 727 a 904 or a A518.

My 69 dart 318 did not have a shroud or clutch fan.

Plenty came with no shroud. Try running it, see if it heats up too much in traffic. You can always add one later.

mine does not

Does the '73 Passenger Car FSM have a chart like this one in the '77 Compact Van FSM?:
