Because I can't afford both.
As it stands, I have a standard bore service replacement 428 block to work with. Have already purchased a set of Eagle "ESP" H-beam rods, main and rod bearings, and have a 1U crank done up and ready for use. Have not purchased pistons as of yet. Have a nice set of C6AE-Rs with dual springs and CJ valves purchased from a forum member who told me his 428 made 500 horsepower with these heads and a custom hydraulic flat tappet cam in the 230ish at .050 intake duration range. Probably only 500 miles on them.
I would like 500 horsepower. More would be cool if feasible but not at the expense of reliability.
If you guys think my goal would be attainable with what I already have, that would be awesome.
If not, would the TFS heads make that and then some on the 428" engine? Or, would a stroker kit get me there with the C6AE-Rs?
This engine will be going in a '67 Cougar, 4-speed Toploader, no power brakes or steering. Must run comfortably on 91 California pump gas.
Would like to keep the RPM to probably around 5500 for longevity sake.
Thanks for any input, guys, Hugely appreciated.
