383 swap for 94 K1500

[20nmichalski]

I’m looking to swap my old tired 350 for a 383 from blueprint. I'm curious as to what I would need to do to make sure the drive train could handle the swap. It has 60e. I was wondering if I should also swap the tranny for the 80e and if I should swap the rear end and if so what would you recommend. I'm also curious as to what headers I should use, I would like some ****** headers but I don't know what would work with the motor and will fit at the same time. If there is anything else I should worry about with the swap too I would love to know.
I also heard of a guy that did this swap and used a built a Monster Transmissions 4l60e that was built. Any thoughts on that?

I myself do not like the 60e in any way shape or form, some have had great luck with them, but not me. If you have the budget, go for the 80e or a manual trans.
The 10 bolt is fine if youre not beating on it HARD, you can always find a 6 lug semi float 14 bolt and swap it in.
Headers, I dont have any info for that. But I do believe there is a thread about exhaust.

I am very interested in this swap as well. Are you keeping the TBI and factory ECM

You probably wanna go to a 50mm TB from a 454 and tune it.

The motor comes with a holley sniper efi so I would assume I wouldnt need to change anything

Wow. $6200 sounds like a lot, but I have almost $5000 in my 350 with a Sniper, and I did all the work myself. It's not a bad deal.

Agreed , this has got me rethinking my upcoming swap.
