5.7 is being put in with a carburetor. It's tbi now.My best piece of advice is to be very specific about the details with whoever is doing the work and put it in writing. You said you're getting a running engine out of an old truck and the intake manifold in your cart indicates it's a lat 80s - early 90s TBI. I saw no mention of resealing, degreasing, or detailing the engine before it goes in your car. If you're only expecting "just slap a tree-fiddy in der", then you probably won't be disappointed. A 4.3 -> 5.7 isn't a direct swap but it's close. There will be some predictable speedbumps -- always are.
I'm in no way trying to talk you out of it. Just want you to have reasonable expectations.
The advice about getting details in writing is good advice though. Thank you.
Switching to a performance mechanical pump that cost a whopping $40 bucks lol from summit. More than adequate and I watched a YouTube dyno test using the same pump.Any plans on the fuel delivery system modifications you'll need in this swap?
This might account for the added time some people have questioned.
I’d keep at least another 1000 aside for the stuff no one thought of .
don’t let these guys make you feel bad for not wanting to do it yourself .
Your car ,your life ,you know what you want
Also , I’ve fixed a lot of stuff homeowners have done on their own home because “it’s easy - just watch a YouTube video and do it “ lol
I’ll pound nails cause I’m good at it and I’d pay a mechanic to do a motor swap because he’s good at it .
And yes I have done several swaps myself ,scratches on frame, header panels and firewalls to prove it
Not to mention pinching starter cable in motor mount putting me on side of freeway at 1am
Or wondering what that little black box does , then drive to buddy’s place and explode the battery all over the trunk
Paying someone a couple grand to do something they are good at, as opposed to doing it myself and not getting to drive it for 2 months as I find time on weekends is a no-brainer for me. I've done all my own body work and electrical and reupholstering. Someone else can drop the engine in for me.
