A bigger cam? What heads are you running?
From what i understand I can't do to much as far as cams because stock spider injection can't supply enough fuel?
IDK, I think you can go bigger but, maybe @L31MaxExpress can chime in. I'm running a Blue Print "383" with a bigger cam on TBI in my 88.

AUS makes a 36, 48 and 62 lb/hr spider but they do not come cheap. 48 lb/hr unit fed my 500 hp 383 on E85 effortlessly and I only paid $300 for it new in the box from a local guy that changed direction on his build and built a procharged big block with a carb.
That's awesome. I had no idea they existed! I will definitely look into that.
What did you do transmission wise to handle that motor?IDK, I think you can go bigger but, maybe @L31MaxExpress can chime in. I'm running a Blue Print "383" with a bigger cam on TBI in my 88.

1.6 rockers will help some. YMMV
4L85E with a custom built converter and Sonnax shift kit and a GM 10.5 FF 14-bolt with 3.73 gears. Its not the fastest thing in the world with nearly 7,000 lbs of van wrapped around it, but it does move out decently for what it is. It makes decent power up to 6,200 but I only shift it at 5,500 for longevity reasons.
