PORT VOLUME-IS BIGGER BETTER OR IS LARGER LESS? Richard Holdener

MOPAROFFICIAL said

302 based motors come with heads that have smaller ports than a 318. This example is really just about useless to any of us...and they went over the factory designed port volume by ...oh 55+cc!?
They basically went from changing to an ideal performance head from stock..to a head that belongs on a 351 or 400cid.

That is called purposeful blundering for the sake of the argument to make a point that's really tired and common knowledge.

Obviously there was no need going bigger than the 190 cc heads didn't really gain but on the dyno didn't really lose, don't think it was meant to be super scientific just he we have these heads and and short block lets see what happens. Lots of his dyno runs are from years ago and he just try's sometimes to see what different conclusions he can come up with the data. But to It does show ya the 190 cc where the best fit for the 302 and probably the strongest runner but I don't think the other two would of been slugs.
