351 hands down. Unless you can run a stroker 302 (331 or 347).

If it were me, I'd find a set of 351M/400 rods (6.5" long or so) and build the short block with them. The big ends are identical to the Windsor part. The extra length maks for a nice short, light piston and a 1.88 rod/stroke ratio.

The early 351W heads (68-70 I think were the years) had 1.84/1.54 valves stock, decent sized ports and 64cc chambers. Upgrade them to 2.02/1.6 valves and call it a day. The later E7TE (5.0 Muskrat) heads flowed decently but won't take larger than a 1.84/1.5 valve without severly shrouding it. Late model Explorer GT40P heads are good too, but they have different angled plugs that could cause problems with headers... and tech inspectors.

The other option is a 351M or 351C. The C is lighter by a couple pounds over the M. The heads of the '335 series' motors kill all the Windsor based heads. Stock 2.05/1.65 valves and (relatively) big ports. But, parts are more $$$ more limited in options and won't spin up as fast as the Windsor.

I agree.....go with the Windsor. If you go with the Windsor or the 302 let me know and if you are interested I will get you the #'s on a couple of vacume cams that we have ran that did real well.

don't totally rule out the 302 base motor its a 100 lbs. lighter than a 351w.I ran a 347 on 9/16 track and had real good results that motor just finsihed its 4th year 0 problems and the stroker kits are alot cheaper now.You can take the 302 up to about 354 c.i.I'm putting together a 408 351w base motor for next year because i'll be running in a late model class next year and need alittle more power.

How much do you have to turn a 347 in order to make the most of it?

I was turning mine about 7,000 with a cheap crank if you put a good crank in it should have something good at 7500 +

I run a 347 also and turn it 8200-8400 but I use the R-302 block and a billet Oliver crank but with the rules you have I think you'd be better off with a 351. My opinion would be for you to run a Cleveland since you have to run stock heads and intake. I used to run Clevelands and now I have my nephew in my old car running a Cleveland. The biggest problem I ran into was getting a decent fuel pump so you don't melt it down as I've done that. Also run the oil restrictors and plumb in a bypass oil line. There is also some other things you can do but you have to decide what you want to run first.
