Spiders, I hate Spiders, Performance

[3dirtwheels]

Hey gear heads! So the HT383 goes in this week. The spider injection system is original. I ordered stainless headers today and think it would be a great idea to open the intake side up as well. The Holley rep wasn't encouraging when we discussed the options, I'm not too keen on 2 computers/controllers and there are no components to make the factory computer to control/talk to their system. I am specifically looking at the Holley Stealth Ram, does it connect to the existing ECU.

Hope to hear some good ideas for spider alternatives.

Only real alternative is a carb/intake/dist swap. Everything else is a computer mess.

That's what I'm finding, grrrr. The Holley Sniper seemed like a good idea, but so far I'm leaning to upgrading the Spider to a multiport Spider with the solenoids on the ends with larger tubing. Thanks

Unless your 383 is hugely built, the factory injection (updated) should work fine. Otherwise, just an injector swap . Kinda a PITA to run the injector wires and make sure fuel lines seal on swap. Had to do it both ways before. Careful when you buy spider replacement for injector swap.

Is there any other product that work without considerable programming issues and/or leaving error codes?

the l31 "marine" intake was the popular swap back in the day. any sbc for vortec heads that has provisions for mpfi should work though. just need it complete with injectors and rails

I believe a Fitech would be an improvement

The updated MPI type spider is a vast improvement. Just remember that you need 61-64 lbs fuel pressure or you won't fire off the injectors. It can be reprogrammed for forced induction.

you get it in yet? I thought about the ht383e but went with a cammed 5.3 ls instead

Yep, just have 2 codes to resolve, runs great, vast improvement performance wise.
