that would be a hell of a trick to do haha. now, what engine do i use for a 429 bore? the 351? cuz thats alot more C.I's thank it started. could it handle it? if this is the motor your talking about? Because, regardless of engine the plan entails boring/stroking, new heads, pistons, crank, headers, and one day in the next 20 years a supercharger. with an extremely built trans. maybe ill hop to a 5 speed. most likely. just need to get some ideas from people who may have done something like this!

429 and 460 are the same motor except for the stroke. 3.59 v/s 3.85.
The 351 would be the easiest swap as the motor mounts and bell housing are the same. I swapped a 351(W) for a 302 in a '64 falcon and noticed a big improvement in torque. The 351(W) has the same journal dia. as the 400 if you're thinking crank swap.
Ports and valves are bigger too. My 302 has a bad knock and I have a 351 core. Guess which one I'm going to rebuild?

Also the 429-460 has a 4.360 bore. If you punch out the 302-351 to that, you'll be pumping water. Along with increased cooling problems, there's a possibility of cylinder wall flex especially if there's boost involved.
Sounds like you should just get the biggest ***** they make (512) bolt it up to a beefed C-6 & hope you don't blow things up. For what you'd be spending on a small block you could achieve similar results with the big block with a lot less stress on the parts and a lot cheaper.

alright, well alot of thinking went in and im in the direction of a 460. a friend of a friend was a hoarder and has a bunch laying around in the original vehicles with transmissions from the 70's. was told he'd prolly just give me one if i pull it. and with the whole rebuild wouldnt matter if the engine needs a rebuild 
how much can you bore n stroke a 460? can i bore it 30 over and then stroke it? when stroking an engine, do you want to make the stroke longer or shorter?

The term stroking usually refers to an increase in length. The easiest de-stroking is to use a 429 crank but that's the opposite of what you want. They make a 512 (or 514?) by stroking somewhere close to 4". Most Ford engines have been the thin wall casting design since about 1965. Usually .060" is the maximum recommended overbore. I once punched a 300-6 .050 to use 390 pistons and while it worked great, it was sensitive to adequate cooling. I would bore the engine to whatever is necessary to clean up the bore and go with that. I think that someone like Summit racing would be a place to start as they might have a stroker kit. Also Ford racing?

the 5.0 loves its rpms and is fairly easy to to build into a screamer with head and cam choice. i personally am like you and very attached to my 1994 f150 4wd 5,0 (306 ci) aode/w stage 1. i just got done with my first engine rebuild and put gt40p heads on . I personally thing my old $962 pig is a little guttless. im hell bent on swapping to edelbrock performer 1.90/1.60 heads, junking my FRPP shorty headers for long tubes and regearing her for more umpf . if i was gonna do it again id have built a 351w due to the fact of more tq at lower rpms and being able to use my Edelbrock Performer RPM 2.02/1.60 heads ( after the trip to the shop to get 1 chamber fixed) which are now searching for a new home cz my performers are on their way. My suggestion is to fig out what its gonna REALLY be used for and decide on a build, set a budget and go for it after you have done all your research. Cheers

^^^^^^^^^^^^^ i got my performers for $670.00 ready to bold on. My performer rpms for $570.00 needing a trip to the machine shop to fix a plug boss broke off by a valve. my engine is already completely rebuilt(700 miles). why would i want to tear it apart to swap out pistons to use twisted wedge heads??? not practical to me and arfs that ive found are $1100- $1500. im not running a radical cam so why would i change out heads to something that will never see any rpms over 5500 max???? not practical at all, just wasted money on high performance parts that i wont use to their full potential.
