If I recall previous posts, Dick has a mechanical pump and
"stock style" hard lines. My '73 Corvette "short tracker" gets
along real well with a similar set-up, which are 3/8 ID hard
lines ( a Holley will "store" more fuel than an Edelbrock) But
hey, how hard is it to run a larger line just for insurance?
Dave asked the question I wanted to; Why such a low red
line??? I assume your new heads have (at least) larger, dual
valve springs, and at least 2.02 intakes.... If so, a larger
bump-stick might be the way to go. Even a 2-bolt main SBC will
take more than 6250 rpm.....
ed (suffering out here in the desert where the highs today
will only be mid-80's)
