    What's a better engine and what would you choose and why? Trying to get opinions to decide what to go with.

    I have had 3 or 4 1978 and 79 f150 and 250 pick ups with 400 and they were great engines but i have also had 2 69 cougars and 3 69 mach 1s with 351 Windsor much better aftermarket and ford for that matter parts selection headers ,intakes , cams and u can bore and stroke a Windsor pretty cheap

    Im wanting to make my ranchero into a hot rod. Something I can go out and have fun in. Do burn outs and race around and beat on. What engine would be a better choice for that?

    A Windsor, by far. Superior oiling system, great aftermarket cylinder head availability, stroker kits up the wazoo. Not to mention smaller and lighter. Plenty of intake manifold choices depending on RPM range, trans, gear, etc.

    I'm asking because I came across a very good deal on a fresh rebuilt 400 from a buddy for $600. But I already have a Windsor HO motor.

    Still would put the 600 in a Windsor 351
    You will be better off in the long haul.
    The clevland based engines are great no doubt but limited parts and short production runs makes it a no brainer.

    X4. It's why I chose to re-engine Babe rather than try to find a 351M/400 to replace the seized engine. Swapping to the 351W and C4, I'm sure, shaved a couple hundred pounds, and the engine is a great candidate for EFI. Just source a 351W from '79 on, and it'll give you the widest array of choices for how hot you care to make it.

    You left out the 385 option.
    If you like the ponies, and tire ripping torque, a big block can't be beat.

    Realizing you've already made your decision, I'll still point out that if you would have chosen the 400, you'd also need to swap out the transmission....400 has the same bolt pattern as a 385 series big block.

    Then I chime in with what I found over the years = The 400's seem to have a resonance point at or above 4500 rpm where the block webbing tends to move or vibrate. This causes the cam bearings to disintegrate. When the cam bearings loose enough material your oil pressure drops enough to get into the danger zone. You can guess what happens if you continue to run the engine with no oil pressure. It is odd that the same basic design in the 351 C doesn't seem to do this. Early design 400's along with the 351M/400 are the ones that suffer this malady. They are great engines as long as you keep the rpm down but the urge for more grunt modifications has killed many of that breed. Personaly, I think they make great anchors for cabin cruisers. Sorry, just my observation.

    Ranchero has a 351m in it so transmission wouldn't be a problem

    Now I have made my decision to stay with a Windsor. I'm thinking of building it into a 392 stroker. What would I need exactly to do this? Also how much power will I gain going from 351 to 392 stroker? Also I will be using the stock heads for now and will go aluminum later down the road

    If your thinking along those lines, a 385 is a better choice.
    You can build one with substantially more power than the 392 stroker for less money, and it will be more reliable and street friendly.

    I'm with ribald1, I thought you had a 351w....go with a big block..no tranny change needed and easy to make hp/torque.

    Thing is I already have a 351w HO and C6 in the garage. I also own a FMX SB bellhousing.
