I have a customer with a 440-6 in a road runner that runs 11.90's using a cam that's 241@ .050 on a 113lca but uses slicks and a 3.91 gear.

manifolds, full exhaust, Stealth heads with minor port work, 10.2:1...he does have some 1.5 rockers but not sure which ones...maybe HS?
He drives it everywhere he can!!

Yeah, Brian I'm with you!

The cam I put in that 416 stroker with the manifolds was very similar to that 440, a single pattern ~237 @ .050 on 112 in at 107, It's a torque BEAST that idles sweet and still pulled the heavy car up high. I think something similar would work on domingo's car and still have plenty of idle vacuum and part throttle cruise torque. My gut would be to put a 244/246-ish @ .050 solid in it and be a bit better down low AND up high.

Wish my old 440 had a set of ported stealth heads and slicks, trying to launch a B/E body on street tires (not even drag radials) was about like launching on ICE.

My buddy's Chrger has a 440-6 with a 251/257 @.050 Comp cam and runs high 11's with only 3.23 gears. He's running 2" headers, close to 11:1 and a good 9" converter though, which helps him launch. He drives it everywhere as well. Wouldn't run that cam with manifolds though But he doesn't even run drag radials, he runs that 4 shock (2 mounted horizonally about the rear leaf segment) traction system and it obviously works good.

You can still build some awesome 440 combos that are still impressive these days!

First thing you need is a tach.PERIOD.Past that I would check fuel pressure to make sure you aren't running out of fuel on the top end(especially if using a mechanical fuel pump).

^ Those guys have you covered on cam selection.I will say my okd 440 with the comp 280 cam was done making power aroung 5500rpm so I would suspect the 270 to be dome by 5200 or so.

There are many cam gurus out there.. I would let Bob k. or Dwayne
set you in the right direction.. These two guys know how to make them
work with manifolds and street tires..

Good luck..
