One of the guys on here…790HP@6700, 689TQ@4900…that was just NA, but that wasn’t enough so he sprayed it with IRC.. a 400 shot of NOS, 461 with 325CFM KRE D ports…Jut saying, that is a pretty darn efficient port for that much HP and only 325CFM.….not mine, but I have a some of his parts on my engine. He has since switch to 528 cid high ports and is knocking on 1000HP, on top of that he has that NOS system. Yikes!

Can’t argue with the round port headers are better and much easier to work on. If us D port guys only knew better…

Do you run studs in your snow tires???

On the subject of the intake/exhaust flow ratio. Here is what Harold Brookshire from UltraDyne said on the subject within a post here on PY:

"On most cylinder heads, whenever I have around a 75 percent exhaust-to-intake ratio, I use an 8 degree bigger exhaust cam.
If the ratios under 70 percent, I use 12 degrees, and around 80 percent, only 4 degrees.
Whenever the ratio gets around 85 percent, single pattern cams seem to work as good as anything."

BUT this was not specific to Edelbrock heads at the time. That could be a general statement from him with factory heads in mind.

And another subject that relates to the type of Edelbrock cylinder head. The older style combustion chambers or the heart shape.

Sure, it was -17 here last week, so the studs work good for the lake ice drags. Plus the cold lake bed is where the drink and drive daily thing works good together too, keeps your senses dulled some so you don’t notice the cold. Just got to remember to steer clear of those ice fishing huts.

is there a good aftermarket coffee maker for a 64-67 A-body? I am having a really hard time finding an original and I just can't see swinging by Starbucks every time I wanna go ice racing ...

…now that would be nice. I”ll keep a look out. Would be such a time saver…I don’t have round ports, so I think that would slow my car down too much though…Maybe if I could find one of those coffee maker’s worth the money it would sweeten to deal so I could justify round ports.

Probably a good thing. I'm not sure studs are compatible with round ports. Where's that donut hole mak'n guy when you need him, He'd troll this deal out!!!
