Re: Looking for a magnum manifold
[QUOTE=Firepower;68036]Would you be willing to share the specs? I was planning to send mine to Delta, when I do my RD450 (532ci) inline. Much worse paired intakes and way undersquare. It'll be fun to see how they compare.
Did you happen to measure/degree it before the regrind?
Did you measure combustion chamber volume?
How about pin to top of piston?
Piston to deck of block?
I'm a big believer in squish, and it seems a lost opportunity with the dished pistons.
These questions that you're asking me were pretty much between the machine shop that did all the machine work on my engine and the custom cam grinder, I did assemble the short block though. Longer valve springs were used since the cam has considerably more lift. The valve springs actually are for a 390 Ford. Since the cam sets on the same centerline it's not necessary to degree it. I'll get the specs out this weekend along with the part number for the valve springs.
