New stroker build

Looking to build a replacement motor for my 95 f150. Looking for probably a 408ci motor. Aluminum heads, torque cam and new intake and long tube headers. Truck already is a maf system. Probably 30lb injectors.
How does this combo look?

not savvy enough to know if there are piston/valve clearance issues.

Better short block out there? or should I say more reasonable? I know there are some for more with higher end connecting rods but don't really know if I need more of a rotating assembly. really trying to get in the 400 hp range with early torque onset.

Listening to any and all suggestions.

I would order the short block from FordStrokers.com. It's a small business and the man running the show will happily listen to your needs and help you build you engine. He does custom cam grinds too, so he's likely a good guy to talk to about piston to valve clearance as well. Phone him or e-mail him and tell him what you want and what your needs are. He'll hook you up.

Check out his short blocks here. Scan through the website and you'll get a feel for what parts he uses and how much pride he takes in his work.

That cam is a small base circle retrofit cam for blocks that did not come with a roller cam, your motor has a factory roller cam so you don't want to use that cam use something like the Crane 35-320-8 instead. Those heads are a bit small for a 408, you could use 180cc to 190cc and not lose any low rpm grunt, but if you use TW heads you should definitely use pistons made for them with offset valve eyebrows.. better safe than sorry.
Your motor is gonna need an aftermarket intake like the TW R-Seres, and the EFI system will definitely need to be tuned for the larger injectors, MAF meter, and increase in displacement. And if it doesn't make 500 ft/lbs of torque at 2000rpm you seriously effed up.

Thanks for the replies

I am checking out the advice guys. I am confused by the cam selections on the Summit site--35-413-8 (what I was originally thinking)--lists 5.8l as a fit and the 35-320-8 lists the 5.0 only.

What about the Edelbrock truck intake? It may be easier to keep the throttle body at the front of the engine vs toward the passenger side and all the a/c plumbing--its tight on that side already with the stock intake.

I was thinking the BBK twin 61mm mounted to the Edelbrock above.

Do you think I will need a quarter horse? I was hoping the ecu could pick up the increased air/fuel flow.

What MAF meter do you like? I hadn't thought about a new maf yet.

Check out fox lake racing engines or Keith craft.I use to run a 408 and a 416 in my mustang,and have built a couple each.all I can say is get ready for some power,and an extremely light wallet if you stay with fuel injection.

As far as MAF goes we always used PRO-M,as far. The ecu picking up the added air flow,it won't you will have to have someone tune it,and have a chip made for it.

You are misinterpreting that, these are both listed as small block Windsor cams, there are no 5.0 or 5.8 specific cams since both motors use the same cam.

No that intake was designed for a stock motor it's no good at all for a stroker, years ago there were 2 members here that put it on strokers and it completely strangled it. The upper portion of most single TB intakes can be reversed so the TB faces the drivers side if you like.

Yes you will need a tuner, there is no way the computer can adapt to this much change on it's own.
