i swapped a ls into my square body truck and am wondering what the ohms are in the gauges for the original square body.

i saw in a parts catalog that i can get sending units for many different ohm ratings.

does anyone know what the original sb temp gauge stock ohm rating is?

Square body? Your going to have to be more specific...also you will get better answers over at performance trucks.

its a 79 chevy used to have a 350 in it. and i want to use my stock temp gauge on my ls swap. so im trying to figure out what the original temp sending unit ohms are for a 350 around this year.

so i can get the right sending unit

If I recall, the sending units for 87 to 91 k5 blazers and suburbans With the tbi engine are the same size and have the same clip on style connector your truck should have. They should use the same gauge as well according to my lmc truck catalog.
However, be warned, tbi engines have 2 temp sending units, one for the gauge and one for the brain.

yeah i just want a single prong to run to my factory gauge. ive already got the one working for the ecm

unless this two prong style would work? i could only use one of the prongs if it would still work this way?
