You want an NA street/strip stroker small block in the 408-426 range that will push a street driven Dart to low 10's, but don't feel W-9's will fit the budget, and have asked twice about W-2's.

Before you pursue this any further, serious consideration should be given to adjusting the budget, or your expectations.


This is an article on the engine build for the car Bill is referring to in his post.

Compare it to MattW's W-9 Build.

Then Check out Mike Crow's 420 Ritter aluminum block build for his 69 5 Speed Dart.

Bill's son Clark (Bad340fish) has a 408 W-2 combo that has completed Drag Week, and is currently in the 10.80-90 range in his Barracuda.

My buddy Darryl went 11.00-11.20's in his 69 Dart with a W-2 408 and completed two Drag Weeks.

Both of these are full interior, real deal street cars, and both engines featured roller cams, and quality component throughout.

My 62 Valiant averaged 10.54 for five days on Drag Week, NA with a 428 conventional head, solid ft cam combo, but I'm 300+ pounds lighter than the typical 67-76 A body.

Crow's Dart runs low 10's, and would easily be high nines with an automatic, but he continues to try and go fast with a stick, in a small tire stock suspension class.

Paul's Demon has been 9.70s-9.80's on his two completed Drag Weeks.

What am I trying to say?
I spent 10K on my engine, and I already had the block, rockers, valve covers, oil pan, and headers. I'm quite sure the 408 W-2 roller cam combos weren't any cheaper.

Stepping up to the MattW/Mike Crow/Paul Cornman type small blocks would be nearly double, I would bet.


Thanks for the info, I've seen a few of those articles before, and they are part of the reason I started going down the small block road instead of my original thought of putting a big block in it. I plugged some numbers into some drag racing calculators, and it looks like if my Dart currently weighs 3500 pounds with me in it, it's probably making 275 hp. It's all steel, full interior, roll bar, frame connectors, always ran through the mufflers. Getting to 10.00 @ 135 mph would take 670 hp, call it 700 hp to be safe. Sounds like a ported set of W2's could possibly get me to 550 hp on a 426" SB. Add a 150 shot of nitrous to hit the low 10's?

Or bite the bullet and pay up for some CNC ported W9's and everything that goes along with them. Might still go that route.

I realize that it's not going to be cheap, just trying to maximize bang for the buck.
