I was thinking about the 302 but I've seen a lot of other people have success with the 351w so i think I'm pretty set on trying it.
how much power do you want?
you can stroke the w to 383, 393 or 410. i would not run a 410 as a daily driver.
Here’s some options
BLOCK – It is easier to get a late model 1971 and later block. The roller 351’s started in 94 with a casting of F4. These blocks frequently crack in #2 and #4 cam journal are, therefore I would not use one for ANY build. The 71 and later blocks are also .020” taller which is what you need for this kit. If your block is a 69, it is worth some money. It might cost around $700.00 by the time it's sitting in the builders shop, just ask them. See photo of journal crack in link below.
Afr 195 renegade $1800.00, or possibly the AFR 205 Renegade if you use the Comp Cams XE284H cam. The builder can do the math to determine this. I’m a bit lazy..
Flow – in 287 ex 220 @ .500, chamber 72 cc’s
Machine head surface approx .012” to 70cc's if you use the XE284h cam with no advance, mill them approx .006" to 71 cc's if you advance it 4 degrees.
Square block – This is unnecessary on mild builds but its nice to do to even out compression in all cylinders. I would recommend it on yours.
Deck block so pistons are .002" - .004" below the surface. This increases compression and reduces potential for detonation at the same time.
Scorpion “race” model full roller aluminum.
Comp cams XE 274H for bottom to mid range power. It will have a noticeable “lope” at idle but will not be excessive. The car will shake/vibrate a little.
XE284H for mid to top end power. You can also advance this cam 4 degrees to lower the power band slightly. It will still be higher than the XE274H. It will have a very noticeable idle but not excessive/obnoxious. The car will definitely shake a little. Anything bigger cam than this is more than I think you are looking for.
Add $300.00 - $500.00 for a roller cam. I might use Elgin high rev lifters with one.
CAM BREAK IN - This must be done by the builder die to the high spring rates in the heads. He can send it out to be done.
PUSH RODS - 3/8" Chromolly
TIMING CHAIN Cloyes double roller with 0 or 2 degrees cam advance $45.00.
If block is align bored you need a shorter chain
Crane high rev $140.00
CRANK DAMPER – get the one with the correct number of holes for your crank pulley. The 7 hole dampers fit both.
Summit SFI certified- certified $145.00
ATI SFI certified - I would run this one to reduce crank vibration and twist
ROD BOLTS – ARP or Chinese forged rods with SRP bolts.
INTAKE - Edelbrock non rpm or similar.
ENGINE BALANCE - $175.00 - $200.00
Scat 393 assy $1050.00
I would have them upgrade to this crank for an extra $100.00.
STATIC COMPRESSION - With .030” over bore, 10.473
