Nope, not and still expect to put it out on the highway at 65 MPH and drive 100+ miles to some of the farther away tracks.

Well then maybe we need to make a deal on swapping out my e-brocks and Mosler ported intake w/your max-wedge stuff.....

I run a max wedge port 60 over 440 on pump gas with no problems.Indy ez head full cnc max wedge port,actually larger than.11.2 cr,small straight duration roller cam,holley hp 1000 carb. Bottom end is stock except for a girdle.Nothing fancy at all.3700#race weight give or take a few pounds. 6300rpm shift point 4.30 gear 29.5 tire.10.72 @126mph it will go faster if I wind harder no need though.

That's probably a good comparison given similar weight, but it would be interesting to know if your combination would pick up shifting at higher RPM.

As described, it's not running any quicker (actually a couple of tenths slower at the same 126 MPH) than what I've gone w/ lower-flowing standard-port heads, less CR, a solid flat-tappet cam, and (coincidently), shifting at the same 6300 RPM. I figure my 4.10s and 28" tires probably work out to comparable RPM / speed #s as your 4.30s and 29.5" tires.

I'm interested in hearing how successful people have been in building 440 RB / 451 B (NOT 469++ strokers) street/strip combinations that use heads w/ Max Wedge-sized intake runners (Indy 440-1s, EZ-1s, MW'd SRs, Max Wedge Victors, etc).

I've met some people (car owners & engine builders) who have similar thoughts that I do that MW-sized ports are really too big for street/strip 440-451 engines (too little velocity, kills torque curve, need to rev pee outta them to make power, etc.). However, a couple of engine builders I've mentioned this to recently have said this isn't the way it has to be and suspect those build-ups used MW-sized heads that weren't prepped to be especially efficient for their runner volume (which IMO means didn't flow enough to justify the extra runner size).

Keep in mind I've been running 440 pump-gas combinations that have run mid-10s w/ standard-port aluminum heads and 11.0s w/ ported standard-size OEM iron heads, both using solid flat-tappet cams. My point of reference is a 3750# E-body w/ 4.10 gears, DOT-legal drag radials and a full exhaust system, so I don't know how something like a 3000# A-body w/ 4.56s and exhaust dumps before the rear axle would exactly compare.

Regardless, I'm interested in hearing what people have done and whether I should be more open-minded to such a build in the future.

What's your definition of street. Driving the family on vacation or 20 minutes to the track?

Brad - have you come to any conclusions yet?

Well... nobody's piped in with anything, so far, that makes me want to change direction from what I've done already. Jyrki's description of the difference from how his car ran first with Stage VIs and then with 440-1s fits is pretty close to what I'd have expected.

My friend Mike Hynes ("THESHAKERPROJECT") mentioned the last time we were driving back from some local cruise-in in The MoPig that the car didn't really feel any different on the street when I got it running mid 10s than it did back when it ran high 11s... it's just a lot faster when the throttle goes wide open.

I chose (and still choose) not to build stroker engines that are better suited to "big" heads, IMO. It's just another one of those trade-offs people need to consider. I'm sure I could find some more HP w/ "big" heads, but would still expect driveability to take a hit.
