I've seen on sprint car engines and drag race engines
that have a #6 or #8 coolant line running to the area
between the center exhaust ports... I didnt do it,
I felt there wasnt a reason to on my engine

I can't remember the exact figures. Small block Mopar has a larger bore spacing than the Chevie for sure. So this may not be as big a deal.

4.460" sound right?

I called on ProLline for many reasons but mainly because they can build and tune the entire engine In House. I may go back with Uratchko, IF he has the room on his list. Last I heard from him he wasn't taking any new customers until he caught up with his Freshen-Ups.

ProLine even admittedly doesn't know SBMopars,(they build some crazy Hemis though) and rather build on the side of caution.

I did let them know about the cooling port between the center cylinders that usually isn't usually used by N/A engines.

As far as Alcohol, They won't build an Alcohol motor without billet heads. They said that to take advantage of the alcohol it would build enough power that it would cause issues with Cast heads (IE: cracks).

They suggested C or Q-16. They said with what I got that I wouldn't be able to take advantage of alcohol's benefits. On that same note I would have to upgrade my fuel system as well. I currently have the Magnafuel EFI 1000+hp system which they said should support about? 2000hp.

We're on the same train of thought.

ProLine has already told me they would have to get rid of the Titanium Exhaust valves that came with the heads. And install Steel Guides. They just won't hold up to the heat and pressure. Inconel would be better but not worth the $$$$ for my application.

I hear this one time and again. Flow Numbers don't mean any or everything which is somewhat true. BUT with boosted applications you want a head that will allow the air through and as much in volume as possible therefore Flow Numbers hold some weight. Granted everyone's numbers for the same heads will vary, so it's better to find heads that have a proven track record.

Yep stroke is your friend on a Boost motor and Compression is as well. Many guys are actually running 10-11.5:1 compression with 25-35psi Boost on race gas. Even more if they run alcohol.

Intakes only need to fit the heads. IE: Same port sizes and not be a restriction. Most of the guys running High-end intakes is because they have to. No decent Intakes to match their heads.

I like to think of it as flowing water in pipes under pressure. Open it up as much as possible and keep your flow and prevent any reversions.

There was a guy in Va. about 1-2 yrs ago, that has an Avenger that he put a 420-something R3 in with W9 heads and Blow Through Carb and 88 or 91mm Turbo made a 6.98sec 1/4mile pass first day of test&tune.

Let me know if you come up with the name of the Guys running the Arrington stuff from way-back.

I stand Corrected!!

Bill Harris's Avenger is 412cui and made an 1/8th pass at 4.75sec 152mph last month during Testing at Richmond Dragway.

Not taking anything away from Bill's car it's flying but keep in mind this a big tire car, not on 10.5's.

I know the guy who helped Bill put the car together. He races imports now.

Bill's car has a big tire on the rear. I forget whos car it was but I don't think it was an X prostock. He runs a 32X14 if I remember right. He also runs a Bruno with a three speed G force behind it. That brought the car to life when he ran NA. He broke input shafts when he went turbo and had to upgrade the converter and everything. Bill runs a real soft tuneup and can go up any greaseball track. I'd bet he could switch over to a 10.5 tire and go up the track with no issues. The car is just not violent at all. For what the car is it is heavy. I think he is around 2,650 with him in it. For a all tube car with lexan that is heavy in my opinion. He runs a raised port W9 head with a 772 intake manifold. To my knowledge Bill has never had to work on the engine from running on kill. So if he really went for it he could go a lot faster from what I have seen.
