Stroking a 351 maybe??
thinking of stroking my 351 block. got the engine out of a 1988 crown victoria police intercepter. I stripped it down to bare block internals were in tough shape all the rings on each piston were broke in half! I took the block had it hot dipped and magnafuxed everything is good.
Soooo now I need to make a decision on what to do with the block. looking for some ideas dont want to spend more than 5000.00 bucks.
I want it for my 1995 f150 which already has a 351 engine.
what do you all think!!

You're making this an EFI motor or carb? If EFI you'll have to factor in the cost of an intake, injectors, and a tuner, because none of the stock parts will be of any use. Rebuild the bottom end with the stroker kit and all new bearings, and bolt on a good set of heads.. Edelbrock, AFR, Dart...

Your 95 will have a roller cam block and your 88 block will be a non roller cam block, I would stay with the roller block as there are some great efi cams. But your 88 block can be coverted to roller with some tie-bar roller lifters, but they are costly. Your 95 should be mass air so you should not have to change the wiring or comp. But like it was said earlier you will need a cam, heads and a good intake also a throttle body, and probably bigger injectors and mass air meter to make full use of a strokers hp. Check my gallery under 96 f250 titled crazyf250 for the list of stuff I have on my 351w, I'm also think of doing a 408 stroker for my truck, I've already built a 500hp 408 efi for my mustang but this more on the drag side. But just a good built .030 over 351 with good heads,cam and edlebrock efi intake will really liven it up. Just have fun with it but don't go over board, and you wont be disappointed.

thanks crazy250, thats some good advice. But how do I tell if the bare block is roller or non roller? I once wsas told that if you are making upwards on 5-600HP you want a non roller block. Any truth in that?

Yeah they say the older block are stronger but I think was more the blocks of the 70's. If the block is roller cam set-up it will have roller tipped lifters and a spider type hold down bracket with lifter hold down bars. Has 2 bolts that hold it down. Otherwise the non roller will just have flat bottomed lifters(flat tappet). The 408 stroker I built for my stang is a 89 block that I converted to roller lifter set-up with some tie bar roller lifters that were about $400 from crane or comp cams. hope this helps a little.
