1984 crossflow intake changes.
Maybe I should have gone to the tech section and will after I write this.
I did what some owners have done to my intake as far as grinding down the EGR portion over the rear intake runners. Now it is smooth and should flow a bit better. I also matched the intake to the head ports. Now, and I should have asked this first, will there be a difference in the injector requirement. There is a front and rear injector, different numbers and labled. Now that the obstruction is gone over the rear runners, will this have any real effect on the demand of fuel from the rear injector? I know this is very old stuff and a one year problem, (maybe the 82's had this too) but I was curious since I do have another set of injectors to replace the unequal one over the rear. Or maybe there were other reasons for the 2 different injectors.
I also put this on general discussion too.
Thanks

Looks great. I didn't build up the outer runners as you did with extra aluminum though. I made a smooth curve and matched but didn't hog it out like yours. Are you doing anything to the engine to take advantage of the work? I guess a dyno might show the differences in gains but I can't feel anything but nice to know its better now than it was. I am not one to know what to do to the ECU and what point it could get overwhelmed by the parameters being changed in air flow. I did put a plate over my egy hole of course as I am sure you will too. I read in one place here where the heat shield hid a lot of aluminum filings so be careful of that too.
What is the iirc en the 1lb/hr iirc?

And I'm very much worked over already.

Wow, it looks strong! I see roller lifters and rocker arms, aluminum heads, and of course headers. No telling what is inside. So I guess you are running the same ECU, map and injectors? I am curious about the cam and pistons, maybe even the stroke too if you are running stock electronics. Why not go with the newer intake that has been offered, renegade? Just curious.

Running an ebl flash for the ecm and a comp cam in the moderate range. I have been told it should make up to 435 at the crank... I will believe it when I see it. I'd say more like 380. 80lb injectors from a late model 454.
