352 Performance Upgrade?
I am helping a friend with a '65 F100 pickup he is building for his son. It has a 352 in it, I tore it down and there is no ridge in the cylinders at all. He was told the pickup had sat for over 20 years, I can believe it.
He wants to build the engine to 400 HP and lots of torque. I suggested a stroker kit, however could use opinions on what would be a good one. Same with the cam.
It came with w 2 barrel, I can provide him one of my spare 4 barrel manifolds, unless there are better suggestions? Use the original heads?
I have mostly worked with 427's, so this is a bit of a new one to me.

400 horsepower is not a realistic goal for the engine in that application. If you want to do a "stroker" bore the block .050 over and install crank, rods and pistons from a 390. Cam cores for FE engines are in very short supply right now so be prepared to possibly have to regrind the original cam core if it is usable. A set of long tube headers will help tremendously over the factory box manifolds.

If you've built 427's then I'd think a 352 would be the same with exception of not having the cross bolted bearing caps. Stroker kits for 427's will work in 352's. For what it's worth, a 4.25 stroke in a standard bore 352 makes 427 cubes. Scat is well regarded for stroker kits.
Parts availability is whacky these days. You'll be able to get the straight answers at some place like fepower.net. Cam cores actually are available from Bullet and Comp but that may change. Ask about cam specs at fepower.net...some of those guys love to talk cams and can get you dialed in based on your goals.
Depending on parts availability over 1 hp and over 1.2 lbft per cube should be easily obtainable with the right parts...depending on the budget...and have a streetable engine running on pump gas.
My opinion is to only remove enough metal to make the bores true and get custom sized pistons. Besides saving metal, you can dial in the compression for what ever heads and stroke you choose and get a more modern ring pack for better sealing and reduced friction.

I haven't read their site in a while but seems like they used to say you had to externally balance which is not true. Mine was internally balanced.

Scat used to be externally balanced on most all of their cast crank stuff regardless of the engine but that seems to have changed on some of them over the years. In some cases they changed the minimum rod length and made it longer which allowed the counterweights to be cut larger. 4.500 stroke big Ford used to be cut for a 6.635 and is now cut for a 6.700 which helps a lot.
The first thing to do is mic the bores to see what size they are. Who knows maybe it was rebuilt not very many miles ago and bored to an oversize at that time.

I'd say 400hp out of your 352 is most certainly possible. Careful parts selection with meticulous machining, assembly and tuning. Contact Brent at Lykins- he's super knowledgable and helpful. Chances are, he's got parts available too.
