That's good to know. I thought the recess was a different size, requiring a chevy thermostat. Didn't know the recess was in the intake.
I had my heart set on that $17 billet piece!

I like the $28 billet 440source waterneck and their $15 chrome one with the 1/2" thick base, I just didn't want to have to order it and wait for it. Shipping is $9.99 for each.
It sucks to be on a tight budget and a tight time schedule.
