Ported Slant 6 head

Fair enough. Thanks for the compliment. Sorry I twisted it. I am building what "I" want plain and simple. It'll pay off big time, because of the sheer difference in flow numbers, so I'm not worried about that. The short block is as follows. 1975 Duster block. Thank you Calvin (clhyer). 198 connecting rods. Thank you Frank (66acuda), with ARP rod bolts and bushed for full floating pins. Forged standard crank, lightened. KB239 2.2 Chrysler non turbo pistons. Oregon custom grind camshaft. .489/.489 230/230 @ .050" ground on a 105 LSA. I am going to blueprint compression somewhere under 10.1. I've not decided where yet. It is intended to be a pump gas only motor, so I am thinking 9.5 or under, although as nice as the head has turned out, I may be able to run more. Any input on that is appreciated. All this will be fed by a 800 CFM custom built and tuned Thermoquad by me on top of a Clifford intake, thanks Bob (superdart426) and exhausted by an old school set of Clifford long tube headers, thanks Bob (superdart426) I have decided to MAKE them work! lol . Also thanks Ed (805MoparKid) for my bellhousing. My goal was originally 250 HP without porting. However, the more I read and talked with people, the more I realized that was unrealistic. I am hoping as good as the head has turned out, that I will eclipse the 250 HP mark. I think I have a good chance. I cannot thank those of you who have helped me enough. This is what this site is all about. That is why I try to pay it forward every chance I get. Oh, and all of this is going in a 63 Dart 2 door post with an A833 OD 4 speed and 4.30 sure grip 8 3/4. It should be fun.

That sounds like a very fun car that you can enjoy every day! It's pretty different from anything I have seen run, so I haven't a clue as to its capabilities. But, I certainly don't think that 250 HP is going to be difficult at all, with it.

If I had a question, it would be in carb sizing. I know that Thermoquads have an air valve-actuated secondary, and ideally, the secondaries don't open unless they're needed, so maybe you'll be okay with this carb, but 800CFM sounds like an awful lot of flow capability for 230 cubic inches.

Ma put those carbs on high-winding 340's and they seemed about right...

Ryan's car makes over 500 HP with a 600CFM carburetor, but I'm not sure how much the turbo affects sizing on carburetors maybe a lot... We are using a 750 on our car, and HOPE to get HP somewhere in the area of 500, but we haven't made 50, yet, so who knows?

Other than that one issue (and I'm sure you have good reasons for what you do), your build sounds great and I think you'll be really happy with it!
