First off Hi. My name is Jeremy and I am builing a 55 Ford F100 truck. I decided to go with a 351W. It's a 1970 block and I got a hell of a deal on a Scat kit and I have a few questions. First a little info on what I have so far.
1970 351 W block being machined at 40 over. 408 stroker Scat kit with SRP forged dish pistons +19 and forged Scat crank. I am also running windage tray and rear sump oil pan with ARP stud kit for the main caps.

The questions are I got too good of a deal on the kit and unfortunately the pistons are dish. Will that affect things too much? Also being that this is my first build I don't know where to go from here on cam head intake selection. I am pretty sold on AFR heads. I am thinking 195 or 205's. Thinking on going roller retrofit but not even close to sure on the cam. I guess the target is 500 hp at about 10 to 1 pump gas.

Use is going to be a hot rod that can be raced but really just want horsepower and a mean sound with the ability to whoop my buddies ass on the drag strip. Is it possible and any recomendations? Thank you in advance.

Dish pistons with that much stroke are a good thing if you want to run that stroker on the street with pump gas. Otherwise, you'd have to pick heads with pretty open chambers. -19 cc pistons should be about right for a 408 with most aftermarket heads. AFR's are an excellent choice. 195 to 225 cc depending on where you want to develop the torque. For a truck, I'd lean toward the smaller runners. Ford Racing only uses a 195 runner on their 427w crate motor. I selected Dart Pro-1's with 195 intake runners and 62 cc chambers for my 420w build. Roller cams are a good thing too, but as far as suggesting a profile; I'm still contemplating that myself! Get suggestions based on you application from the various cam grinders and pick one, that's what I'm doing.

Thx mtn. Yeah the cam thing stresses me out. I am leaning more toward building enough torque to pull a house rather than hp. It's just so great to be able to say "eh it's only got 550 hp".

If figuring out the cam stresses you you can always call the guys at Cam Research in Colorado and they will take all of your spec's plus what you want out of the motor and come up with a custom grind for you. They are not much more expensive then an off the shelf cam. They ground the cam in my '70 Mustang's 351w and I am very happy with it. The profiles I am looking at for the '64 Fairlane's 420 ci Windsor are slanted more toward mid range power for drag racing so might not be best for you. Try Lunati's cam quest program on their web site. Its free and quick and takes into consideration all of your details plus intended use. I used theirs and Howard's and the profiles came out very close. They also were very close to what Ford Racing puts in their street/strip version 427 ci Windsor so I feel pretty comfortable with them. That engine puts out
450 HP/530 FPT, which is what I am looking for.
