Well, the H/G's popped on my Cougar and I'm throwing my GT-40 iron heads on and an explorer intake....
I need to know what size hole to drill and tap for the intake air temp sensor and the coolant sensor on towards the back on the driver side...I'm doing the heads/intake on Thursday and need to know ASAP!
Thanks in advance,
Don
What I did is bring both the act and the lower to the machine shop and they sized and taped it think it cost $10 or $15 dollars.
Also remember those GT40 heads off explorer are like 64cc so you also might want to mill and cc them
Well, I got it taken care of...I went out and got what I needed. The car is a hell of a lot more responsive now...however I need to shim the roller rockers a bit.
