Thanks for the help!
On my 64 vette, the temp sensor is the same,almost right under the thermostat housing,performer rpm intake. Didn't have enough clearance. The solution was a new housing, I believe it is a billet specialties. Raised the hose about 1/2". All is fine now.

A buddy of mine put vortecs and an Edelbrock Performer on his 70 pick-up. He installed the sender on the port facing the radiator. I can't remember if he used an adapter or not and he has since sold the truck.

we've ALL (me too) missed the fact that he want's to use the idiot light....
wander down top the parts store and find a sender for a light AND has the correct threads, change wire terminal to fit.

Allright, I messed around with my wife's digital camera and was unable to get a pic for you guys. Sorry. I definately cannot fit both the sensor and the thermostat housing though!

Here's what I am going to do . . . for now. Let me know what you think. What I really need to do is get this motor fired so I can get the car to my bodywork guy before winter (remember this is Wisconsin and winter is coming soon!)

I went to the parts store and got a brass plug for the sensor hole in the vortec head.

Then I got a Mr. Gasket radiator cap with a temp gauge on it!

I plan to set up full instrumentation in the future OR use one of the thermostat housings that has a sensor hole in it. I don't want to tap the manifold in another location, so I think a new housing will be best.

So. . . will the radiator cap temp gauge be okay for now? Remember I haven't run this motor yet, so I need to make sure my cooling system is working allright. What temp should I expect at the radiator cap? I've got a high flow water pump, 180 degree themostat, and I just had the radiator rebuilt and turned into a 2-row (not sure if you can believe this, but the stock 307 radiator was a single row!).

I was thinking I should be anticipating around 180-200 degrees at the cap? Any ideas? . . . or problems?

Thanks for the help, guys!

IMHO, the rad cap guage by itself in not good enough. You will be seeing radiator temperature not engine temp. IIRC, there should be a listing for a smaller thread sender that will work. Blue Streak or hygrade products, maybe?

A real auto parts store might have a paper catalog with a cross-reference guide where you could see what's available with your thread size.

Might email Scoggin-Dickey's tech department (tech at sdparts.com) and see if they can help you. Surely they've dealt with this before.
