I just got a '75 F-250 and i'm buying a motor to rebuild. The block casting is DIVE-A2B which i found on here is a 429/460. My first question is how much of a difference is there between the 429 and 460 as far as power?
Generally, on any given year of production the 460 base passenger car engine has more overall power than the 429 base passenger car engine.
And i'm pretty sure but can someone just tell me for sure that this will bolt up in place of a 460?
429/460 engines, on any given year of production, use the same block.
i found on craigslist DOVE-A heads built with all kinds of goodies, the guy is selling the pair for 495. They've been hot tanked, magged, all that. The heads on the motor i bought are D3ve or Dove-3, i can't remember. I've heard that the DOVE-A heads are really good, should i get those or is it one of those six of one, half dozen of the other situations?
D0Ve heads will raise compression about 1.5 points over a D3VE head. However, the valve trains between the two cylinder heads are not interchangeable and so you need to purchase a a complete vavle train i order to run the D0VE heads on your later engine.
Last question is with either set of heads i wanted to get them decked to get a little more power, should i even bother with this? if this means performance cams and such what all would i need?
In your case, it's not necessarily the heads you want to deck...it's the block. If the shortblock is not coming apart at the moment, then don't worry about it.
I suggest you use the search function and start reading.
