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???
