iron head capability
im not really familiar with all the different casting numbers, i believe its the D2VE heads that suck bad so besides them, what kind of power are the DOVE and D3 heads capable of on a stroker motor of 545ci or more, stock, ported and otherwise? I've read that a big stroker even with iron heads can potentially make 600hp or better, so which heads would it take to do that and which heads are normally found on the late 70's 460's in pickups and what could you do with them? Are 460 rockers adjustable or would you have to replace with adjustables to run a solid cam, not roller just solid? basically i hope to build a 545 in the future but probably wont be able to afford aluminum heads and roller valvetrain, so a budget stroker if you can call it that

I was hoping that the d3's were the ones on pickups because like you said they are more easily come by. i'm am surprised however that you cant get away with 10:1 compression or even more. even with a mechanical cam with 250 or 260 degrees of duration and around .600 lift? 10:1 is pretty good but can you get 600hp with that, i guess with 545 inches its still very possible. the biggest motor ive ever had is my 422 FE so i really have no idea what to expect from a 545 built with even better parts. One more question if nobody minds, how much advantage in power will you gain by using a mechanical cam vs. a hydraulic because i have seen some pretty gnarly hydraulic cams too

theres no power advantage to using a solid cam over a hydraulic of equal specs, but with a solid cam you can use more lift and quicker ramp rates, and they arent rpm limited- hydraulic cams will "pump up" and not go much past 6500-7000 rpm regardless of the cam theyre on. hydraulic rollers are even more rpm limited, they cant go past about 6000 without floating. solid rollers and hydraulic rollers do have a power advantage though because they dont have as much friction.

yep, a hydraulic cam is fine, you just have to make sure your pushrods are exactly the right length with a push rod length checker. if you want roller rockers though you will have to have the heads machined for studs because any full roller rockers are stud mount. if it doesnt matter then just use the stock stamped steel rockers
