Brainstormin' 440 vs 5.9 ...

That's what Vixen's current engine's head was milled on. One end slipped off before the guy caught it. He tried his best to straighten it out, but it ended um milled crooked. You could see the difference in chamber sizes from one end to the other. I had to take it to another friend who has a Rottler and he milled it back straight leveled off the valve cover rail, since the rails on a slant 6 head are a machined surface, parallel to the original deck. Overall, I ended up with about .180" taken off. Chambers went from around 60cc to 34cc.
Totally outside of where we were going with this thread, but Now you got me wondering about angle milling a slant head…
 
I think Tim would shudder at the price to mill .100 off, on this build, with the budget he is aiming at. If he was closer, I'd let him do it on the van norman 570.
you have the "fancy" one. we had the "rock" that we raised or lowered and ran the heads over. did you know, that after "cleaning" the cylinder head three times that way, the intake bolts don't line up? took the heads off and "cleaned" the intake side. everything fit now! Thanks Bob for letting us use the machine shop after hours! (and not me, Bob Clark the owner of Village Auto).
 
a little more food for thought: @Babyblue66 did a 440 that cranked out 420hp 480tq. granted a bump in compression to 9.6, the rest of the recipe follows with 906 heads that were breathed on a little with a bowl blend and 222/234 cam on a 112 that was sub .500 lift, topped up with a performer rpm, 750 and headers.

again, super straight forward combo of parts gives good results.
With 7.4 compression and virgin heads, I'd bet that same engine would struggle to make 360 hp.
 
My 70 Charger ran 12.30s at Wooburn with a stock NYer shortblock, MP template ported 906s , headers and a .550 short duration roller cam . I was running a 6pak but a good single plane would have worked.
4000# with driver.

I also had a 65 Coronet 500 with a similar build except a MP 284/ 484 cam and tM7 intake .
It ran 12.9s .

But you will exceed your $500 budget .
 
It's time to break out the dremel , open the port up, gasket match head and intake, it's only time and a few bucks for a burr, winter is upon us.
 
Yeah, get to porting the 452 heads and port match the Torker intake. Sell the 906 heads to put towards the project. What do the pistons look like on that one? Are they flat or to the have the huge reliefs cast into the crowns?

you want me to port the 906 heads then sell them?

 

Sounds like Tim might be in for a road trip, do you like pizza, he's been known to road trip for pizza.

If he drove 5 hours, I'd have my wife make homemade pizza!

No worries on a block falling on mine, I have a Blok Tru setup.

I have homemade holders for some heads, that set up on the Blok Tru's 2" bar.
 
not me, I'd have to make use of winter and breakout the burr and put a cam in at the very least, I have time and a $500 budget to work with.
I actually did touch up a little with a dremel on the 452's. The 906 are on the 383. They look really good, and that engine had a decent cam in it so I don't know if any work was done on the 906 heads or not.

Do you still have that cam/lifters? 440 might like them..
