Okay, let me start by saying I tried to search for hours on end for an answer to these questions on the board. Maybe I'm wording it wrong or I don't know but not finding what I'm looking for. I am in the process of doing an L31 vortec crate engine swap. I still have a laundry list of parts to buy but have got most of the big stuff out of the way i.e. long block, intake, carb, fuel pump, relay kit, all drive accessories and brackets, alternator wiring and info THANKS VETTEVET, and power steering pump/steering box swap info etc...I may be forgetting some things here but its been a long week...

What I need to relieve my headache here are some first hand experience recommendations on a few parts so I can continue with the transplant.

1. throttle bracket for vortec head/edelbrock 7716 manifold setup with a th350. Ive found the edlebrock bracket but it gets horrible reviews. I will go with it if all else fails and make it work.

2. I have a starter(high torque mini some off brand) from the old motor which is from a 65 pickup(it has the 4 hole provision for 153 or 168 tooth flywheel. Mine is 168 one piece rear main style). not sure if it will bolt onto new motor. id look but its at the shop and I'm trying to button up my shopping list. so is it an offset/diagonal on the new block? metric vs sae? block number is 10243880. L31 HD 5.7 crate

3. fuel pressure regulator, bracket, guage for the fuel system. I bought a holley mighty mite(which ive found to get terrible reviews but not til after I purchased it) part number holley 12-427. Its a 4-7 psi pump and carb I bought is a summit 600cfm which calls for 5-7 psi. I assume I should still run a regulator and I am not planning on running a return system(tank still in stock location behind seat).

4. Fan options for this water pump which is a spin on hub style. I have the junkyard find but not sure I want to run it with the used clutch or how to test clutch.

5. Headers that fit without modification in our trucks with L31 crate engine. Keeping in mind frame rail clearance and starter etc. I have some already bolted up from old engine but they are getting pretty crusty and rusty and I'm not sure the brand. They came with the truck and I'm sure they are a cheap set. Trying to stick with long tubes so I don't need to modify the rest of the exhaust system.


If anyone has experience with this I would appreciate some feedback and thank you in advance!
