24 pound radiator cap was a big help for me also " with the bb the standard
18lb just couldn't do it . I also use a 16" puller with complete shroud I can let that car run
Till it runs out of gas. Never goes past 95c water. 105c
oil and that's beating on it on the hwy and back roads 4500 rpm plus.
My rad is also tilted and I have the little push bleeder installed in my intake, that little
15$ thing is priceless. Bleeds my motor in seconds.
