What heads are you running Rocco? I was surprised everyone said my heads were sub par...you need trick flows or indys etc.. but I ported and used what I had and am happy with the results.Same exact power band and peaks of my 440. Your hp number is a touch bigger. That engine will be fun to rive

I would be happy to be at your levels I'm honestly a little worried about pushing the block too far getting close to 650. It's more than I had wanted really.Performer RPM, max hand port with 2.20 intake valve. 345cfm on intake.
Mine made 575tq @ 4500, 602hp@5,900
I left a lot on the table with the cam and it wants more carb.
That’s the internet and most knuckle heads at large.I was surprised everyone said my heads were sub par...you need trick flows or indys etc.. but I ported and used what I had and am happy with the results.
im planning on doing this exact same build with different heads. Going into my 69 notch mated to a 4 speed with 391.The 400 is choices around here and everyone is looking for the “right” 400 block. IMO, the B 383/400 is a excellent block to stroke.
I guess that means you are happy with the work he did on yours as well?Craig does an awesome job porting. What r ur flow numbers? Very nice build. Kim
Are you still retired ? It's been awful quiet down in that area, very few earthquakes.Those power figures and flows are about right. The 440/496 had RPM heads that flowed 292 @ .500" and 309 @ .600". Used a 249/255 solid roller and .585/.600 lift. It made 642 FT-LBS @ 4,600 rpm and 641.6 HP @ 5,800 rpm.
Our RPM heads just like roccodart440 made 787 HP @ 7,200 rpm with a pump gas 400/451.
I haven’t built my motor yet but they sure look purdy. KimI guess that means you are happy with the work he did on yours as well?
I will have to look for the sheets but if I'm not mistaken I was right at 300cfm @.500

Yeah it probably would but I'm not after every extra horse and if I can use some cheap b body hedmans over tti I'm all over that plan!!With those numbers it seems it would like 2" or bigger primaries.

Yeah I'm in Canada though but I suppose if the price is rightUnless there was a guy that would sell you a set of TTI 2" headers cheap.
hint..it's me..
