stroker 351 windsor
i havent done it ,but it is done all the time in the mustang crowd.the front of the crank has to be machined down to 351 specs, block has to be notched for rod clearance. not sure on rods and pistons. look in super ford magazine or muscle mustangs and fast ford magazine at various engine company adds they sell anything you need. you can build up to 454 cu ins,but the rod angle ratio gets excessive @ that much, 408 or 392 cu in you can live with.ford sells a 392 short block or a complete engine. go for it!

An easy stroker to build is using a late 351 block (72' up) with a 3.85 stroke crank from summit($549.95), your stock 351w rods, and low compression 302 pistons. Need to get aftermarket heads such as AFR 185's to make any decent power, as the stock windsor heads are too small for even a 289.

I presently have such a shortblock being done at a local machine shop. 400V8 crank with the snout shortened, thrust areas and journals machined to duplicate the 351W crank specs (020"/.020" under). Stock 351W rods with smoothed beams, ARP bolts and .927" pin bores. Silvolite #1472 Chevy 350V8/305 head +.040" 29.5cc dished top pistons. '70 block checked and machined for rod bolt clearance; ARP main studs and TRW bearings used with the main bearings drilled to match the oil feed holes in the saddles. I'm shooting for a +.010" piston deck height and right at 10:1 compression if I use aluminum heads at 64cc and just over 9:1 if I use iron heads with 68cc chambers. I haven't decided what heads, cam or intake I'll be using yet. If you use a post-'70 block, the pistons will be .004" down in the cylinders (easy to get zero deck height with a simple block clean-up).

how about using a 400 crank 351w rods and boss 302 pistons with a comp height of 1.529 would be .005 above the deck the felpro head gasket has a copressed height of .039 if i checked piston to valve clearance and maybe flycut the pistons if it is required it should be good right? or is it bad to have the piston above the deck?

Depends on how much compression you want? Also are you willing to tear your engine down once a week to make sure you can still run the 1/4 to the light and push it home and into the garage again? Just kidding. Honestly I have heard of people doing it but never heard if they had any problems resulting from it. If you fly cut the pistons are you going to end up cutting them too much and making the piston top weaker? Best bet is to call a local machine shop or wait for a machinist to answer this one. These are just my concerns when doing something like this.
