Guys,
I'm looking to add some ponies to my '74 400 w/4x heads. Money is sort of tight as I have a wedding to plan n pay for, here comes the what if: What if I have the heads rebuilt and add rollers in the process, along with changing out the cam to the Melling 068, or SPC-7, and finish off with a 3.55 rear ratio? How many horses do you think that'll add and how much can I expect to dish out($$$)? The car already has dual exaust and breathes thru a K&N. All ideas welcome. Thanks
