Engine swaps?

[Broken_down?]

Got a lead on cheap 02 Chevy Van Express 5.7. Wondering if it will mount to the th400 in my 68? If so will the heads and intake from 68 work on the 02 5.7? Anything other things I would need to know?

Thats not an LS engine FWIW, van's didn't get an LS variant in 5.7.
That said, I believe your th400 should bolt up.

Any idea if the heads and intake from 68 will work on the new 350 motor?

Yes

So if the block will mount to the trans but the top end is fuel injection I will need some kind of aftermarket intake to utilize the current 02 heads right? What are my option here?

Heads & Intake from a 68 SBC will bolt to a 02' 5.7L Vortec short block.

Use the pushrods from the 02' Vortec, Use the rocker arms from the 68'

There is no hole drilled in the block for a mechanical fuel pump rod....You will have to use a electric fuel pump.

The water pump bypass hole is not drilled in the block, Use a water pump gasket as a guide to drill the hole.

Install a melonized distributor gear on the 68' distributor..... http://www.summitracing.com/parts/ACF-10456413/ This is a MUST with the roller cam.

OK so here is what I have gathered for my options:

Option 1:
1. Heads & Intake from a 68 SBC will bolt to a 02' 5.7L Vortec short block.
2. Use the pushrods from the 02' Vortec, Use the rocker arms from the 68'
3. There is no hole drilled in the block for a mechanical fuel pump rod....You will have to use an electric fuel pump.
4. The water pump bypass hole is not drilled in the block, Use a water pump gasket as a guide to drill the hole.
5. Install a melonized distributor gear on the 68' distributor..... http://www.summitracing.com/parts/ACF-10456413/ This is a MUST with the roller cam.

Option 2:
1. Utilize the entire new motor and buy a new intake: http://www.summitracing.com/parts/EDL-2116/
2. Recommend replacing the weak vortec springs with some LS1 beehive springs. Comp cams makes special retainers (http://www.compcams.com/catalog/COMP...12_353-355.pdf) call help line for comp cams for this and the beehives don't require machining like the double coil springs do.
3. All your mounts and accessories should bolt up no problem. Optional to go with a serpentine belt setup from a 91 Chevy pickup w/350TBI engine. Avoid Astro van serpentine setups, everthing mounts backwards from standard.

Option 3:
1. Leave the internals stock and throw a new intake for vortec heads on it and go with a new intake(http://www.summitracing.com/parts/EDL-2116/). Need to put on the hardened distributor gear (http://www.summitracing.com/parts/ACF-10456413/) for the roller cam.



Look OK?

Looks good. Just depends on what you want and what you want to spend. I wanted an LS1 and 4L60e but couldn't find one for less than 3500 around here. Got a complete 5.3 and trans for $1200. Not as cool but runs good for way cheaper.
