It’s not really that much different of a head than a ported EZ head.......like an EZ295.
Power should be very similar if the heads got swapped on the dyno.

Well, the top end is already sorted out....... 500”, decent cam, enough CR, ......... 700 wouldn’t be that hard.
The “intended use” dictates several of the decisions...... including the cam.
The intake, cam, carb, headers can easily move the number from under 600...... to over 700....... from the same basic long block.

I’d like to stay at .650 lift or less and a lobe that doesn’t eat springs. I also have the trick flow intake for it. May take some creativity to port match. Can I make similar numbers with a hydraulic roller? Or will it require a solid roller? I want something that can go 40 mile trips and maybe go 4-5k miles before swapping springs And rebuilding lifters.

been running mine for a couple years , is an RB though . Both a 440 and a 505 .
I run solid flat tappet cams , no rollers so I am sure I am leaving some hp on the table . But mine is my daily as well as bracket racing . Raced on 98 pump gas and through the exhaust .

My experience with hydraulic roller = DON"T! My plan is to get a cam from Duane when that time comes. I’d prefer a solid roller for this build. Just not sure how aggressive I want to go yet. This will be a street/strip car. I’d like to stay between 260-270@050 and .650 lift. If I can make 700@6k rpm that would be amazing. 337 won’t work for me as it’s a low deck, but an Indy intake won’t be out of the question.

My duration is under 270. Mid 260's. Thank you 🙏. I’ll contact Duane and tell him I want similar specs. Do you remember what your torque peaked at? And do you have times yet?

I don't really know what rpm the torque peaked at but it was low. Peak torque was under where we were starting the dyno pulls. We started one pull lower to see peak torque but can't find that sheet right now. I have not yet finished the car. I need to get moving on it...........

Thank you Andy! Does it seem these combos have diminishing returns the bigger the camshaft you go? If you 252@050 cam will get me close to 700 and a 265@050 only gains me 15 more I’d rather just get the best bang for the buck and not try to squeeze every last pony out of it. Where’s the point of little return or am I off base? Also do you feel a hydraulic roller could get close to the 700 mark? I know trick flow claims 685 with these heads and a mild build but I’m not sure as an average builder without the use of exotic parts I’d reach that with the same combo.

I agree with you on the 500+ stroker large duration cams. I'm in the same position with my street/strip 12.5:1 511. Currently using a 270@50/.645" and thinking smaller with more lift might be the ticket. Seems the 470's handle a lot more duration than the 505, 511's do. Also in a medium to heavy street car, something on a 108LDA would work real nice instead of the common 110,112LDA, without power brakes. Being that 500+ strokers make power down low and big duration cams make better power up high in the power band, it does seem a big cam in a 500 stroker in a street/strip car would be a bad combo. Maybe someone here can prove this wrong. I would like to see those combos.

How about the 470 using TF heads other than Andy's is anyone making close to or above 700
71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it. 67 Belvedere that worked it's way in the 10's
