Always interested!! Have you ran them? Which block you running?
 
They're going on a 72 360 block. 4.100" bores with a 4" stroke. Has over .160" left in the walls. Been grouted Street fill.
Modified Super Victor and Dominator. Solid roller cam.
Still got to get the cam, rockers, lifters, pushrods and stud girdle. Hopefully get back into it next month. Got a friend helping me with the finer details like cam selection etc.
I'm building a 383 with stage 6 heads as well but I've come across a 400 block so I might go that way and sell the 383 bottom end. I'll do another thread about that later.
I'm not sure which numbers are which. Is it 370cfm@600 or 319cfm@600?
 
I was always told it was not easy or cheap to put 48 degree heads on a 59 degree block.
you have to move push rod holes, change rockers and run offset lifters. Or am I mistaken?
 
Have to clearance the pushrod holes. I'll be running offset MRL lifters too. Shouldn't be too much of an issue.
 
Read the Bottom line. W2's are not capable of 370 cfm.
 
319 @ 600 & 325 @ 700 is wrong because your buddy has a CNC machine the produces less by a few cfm. OMG! Get real!

Click to expand...
Not my buddy just showing flow numbers with a similar head i bet if they were flowed over there they would go more lol
 
Ops! Sorry. In that case, good luck with the build.
I'd like to see some documentation of the mods for 48* heads on the 59* block done if it isn't to much trouble for you.
 
When I get back home next month I'll post more pics and info here. I can't wait.
 
WHOA! Out to sea on a oil derek? War? Holy Moly! A month?!?!? I don't think I can stand it!

Looking foward to this!
 
these are just square ported to and indy 245 cnc gasket size by the looks which is nothing new landy was doing this to these back in the day but where much larger in the runner and over the short turn and flowed more than 319.......top line is flow @ 100 percent of the oriface middle line is the percentage of that flow at the lift last line is what the head flows at that lift so 319 which ever way the have good low lift flow and are capable of make 600 in the right combo .....well done for thinking out of the box
 
300 cfm should good for 600 HP? Yes, with the right parts.
 
319 cfm equates to 655hp potential power providing the intake doesn't hold it back as well and the combo is good right cam, comp, quench and pipes etc there are many eddie combos ive seen that make more than the head can flow ......most 408's will use all of the head farily easy ....will be good to watch the out come of this combo :happy1:
