I checked both those web sites, and thanks for both. It looks like the modern retrofit tanks are not available for our A body cars. The one with a sump looks like it will improve things, but the fuel pump would still be external. I will come back to these web sites after I get things going, if it looks like fuel starvation is part of any further problems I experience.
I have re-routed the fuel line, and am re-doing the entire intake tube from inter cooler to TB. I am getting the blowoff valve up on a flange welded to the upper 2.5 inch tube intake tube, , thus eliminating the restirction, and cramped quarters the BOV previously presented. It was previously in a smaller plastic tube that went in line, which meant the tube size had to be brought down at the blowoff valve. I am enlarging the inlet and outlet on the inter cooler from 1 7/8" to 2.5 , like the rest of the system. Some of this requires aluminum welding, which I must farm out. As I understand it, these restrictions do more than just restrict the flow, but cause heat, which is what we are trying to eliminate with the inter cooler. I will also go with a cooler plug as was suggested elsewhere buy Anothersix.
I am hoping the intake work, and cooler plugs will solve the detonation problems, and that the change in the fuel line will solve the fuel delivery problems. Of course there is the "minor" thing of now knowing for sure what injector size I have.
I enter the new season with re-newed hope.Sam
