so it begins.....
Well I'm into the rebuild. THis car was my sons when he first received his drivers license and I wasn't sure what was under all the bondo the previous owner spread with a trowel
It is a 69 Mach but there has been quarter skins replaced. I had to get the panels with the scoops as the skins did not have the scoops. Goal is to have the passenger side roughed in the next week and start the drivers side.
Now the engine.... what to do with a tired ol 351W.. Stroke it?

nice car, and that is the million dollar question, "what to do with the 351?"
Really depends on what you want from the car, daily driver, weekend warrior, or show and shine?
There are tons of threads here were we have discussed all the many possibilities, but for myself, I went with a new 4-bolt main, and stroked it out to 428c.i., I will probably never fully use the engine to its potential, but just like my work trucks, I always build to worse case expectations. That means ceramic clutches, largest brakes, strongest trannies I can get, a broken down truck in construction doesn't make me any money, and then I don't have any money for my stang!!
If you do stroke your engine, I would really recommend you do a disk brake conversion kit first, so you can stop those horses after you set them free.
But most importantly.........have fun doing whatever you do.

Looks like a good start, my old 351W? Is now a 426W. The only way to go to for me.

I'll speak for myself here, but i went the safe route with my windsor....here are my mods on the date correct '69 block:
Block bored .030 over
Original '69 fully ported heads(they flow 240cfm) with larger Ferrera intake and exhaust valves....
Stud mount Scorpio rockers with roller tip...1.6 ratio
Double forged valve springs
Forged flat top pistons with 10-1 compression...
Forged pushrods...
Original crank turned 10-10
Comp cam 292H for street use but with a somewhat rough idle...kinda like a 440 mopar out back...
I kept the original 4 barrel intake on this set up so i could fit my shaker unit...
Holley 650CFM
On the dyno at the flywheel:
420HP at 4500 RPM, 440TQ at 4700 RPM
Very muscular sound, music to my ears....
Should get about 15MPG when driving it gently...

408 - 434 Clevor. Pop Cleveland style CHI heads in 3V or 4V and stroke it. They are making incredible power #'s.

I'd build a bulletproof 351 with enough 'yee=haa' to keep it fun.

I've decided to stoke mine to a 393. Its going to cost about $200 more in parts and $100 in machine work to go this route. I'm guessing the $300 will give me 25-50hp more.
Musman, did you get your 420HP with the stock '69 351w cast iron intake manifold?

Yep, i sure did, we actually wanted to shoot for 380HP, i wanted the motor to look stock as much as possible so i decided to keep the original C9 intake and port match it with the fully ported heads....also i was going with a shaker, so i didn't want the shaker to come out of the hood too much....boy were we surprised to see 420HP at 4500RPM, and best of all is the torque...440

Well here we are after a long HOT summer and we're back on the project. Feel we made the turn and the worse is over with two new rear qrts and the back piece. Have one door to skin, align the front fenders, prime and back to my house for an engine.. Now the hunt begins for a stroker that I can keep the shaker on!
