blocking air flow too much?

yup....think i figured it out myself....I took the shroud off, and hole-sawed 6 2" holes in the 2 corners that were covered....i went for a drive and temp stayed around 200 til i got on the interstate and back off....then it went to 210-215....but didn't keep going up....

guess my shroud idea wasn't very good....i'll have to go get some aluminum stock to make some mounts and leave the whole radiator open....

hopefully i can get it to run at 180 at cruise speed like it did before i pulled the engine
