440, 12.7:1, DC. .590 sft cam, [email protected], MCH ported Eddies (322cfm), Victor int. 2" hdrs, 1050 Dom..track hp was 601fwhp as per weight/mph showed....thats real hp not dyno stuff.
600+hp from a 440 with TF240's@10:1 is going to be tuff even with a big cam as in .630" range, 240's flow 323@600. Go 512ci with 270's and a .620" and 650hp can be done much easier and @10:1.
