[QUOTE="Pro SNIVELER, post: 9117645, member: 34027"] they are edelbrock heads, and ported...... but probably only flow a minimal amount more than the OP's out of the box 170cc tw heads. dont let the smaller TW's fool you, they make power with inline heads alot larger due to their design. their cross section is closer to a 185cc head. a guy on corral ran a set of 170 tw's on a 408 deep into the 10's trapping mid 130's NA and pump gas. i seriously doubt 9psi will be needed with a 9:1 347 to achieve 450rwhp. id start shopping the forums since its becoming winter, for some used 1-3/4+ LT's and some suspension upgrades. minimum 3" collector on the headers/ 3" on the mid pipe. your intake isnt going to make crazy power on a blown 347 either. once you go with more cubes, your 302 parts become bottle necks/restrictions and your 20+ year old chassis takes massive abuse in stock trim. if i had to guess, id say that car made/makes that power because of the meth inj and not in daily form. it may not be a street car at all, but the numbers are going to be very similar when this gentleman builds his.
