i also have stock 92rs and planning the swap to 350. can you tell me if the below setup will work or if you guyz have any suggestions:
1. 3970010 SBC
2. Lunatti Cam #10120208
3. Edelbrock EPS intake manifold
4. Holley electronic chip Carb with open element filter
5. upgraded fuel pump, regulator, fuel rail, gauges
6. Performance pistons
7. Spitfire or NGK plugs with 8mm performance wires
8. longtube headers with flowmaster 60series

rest all will be transferred from the old engine. gear is T5 stock along with the differential

also what numbers are we looking with above setup

 

2-piece rear main seal, flat tappet. Kind of a downgrade from what you have in those two areas. Have you considered a '87-'95 block instead?

A "single pattern" cam. SBCs usually do better with a dual pattern. What heads are you planning on running?

Not bad, but not great. Really depends upon heads & cam you have.

No clue what that is.

Dual snorkel would probably be better.

Can't say without knowing exactly what you're talking about. But, an upgraded pump will likely be required.

???

Sounds like an ad from a shady eBay seller.

NGK.

Depends upon what the wires are. See "performance pistons" above.

Which ones? Long tubes typically reduce ground clearance, make exhaust routing difficult.

Depends upon the heads. If they are what came on a typical 010 block, then "disappointing" is the operative word. Need to know what heads you're talking about.

 

i have gathered some more details as below

This is my first swap and on a tight budget, so ill need input from all of you experienced guys.
one of my friend suggested vortec heads, what are your reviews on that.

 

About the only choice worse than LO3 heads would be "882" heads that came on a 010 350 block. So, yes, Vortec heads would be MUCH better! Of course, that will require a different intake manifold, but well worth it (even on a limited budget).

But, Vortec heads don't allow much valve lift from the factory. So, you either need to have the heads machined for better valve springs, use "beehive" valve springs and retainers, or buy heads already modified. Personally, I think this is a very good deal https://sdparts.com/details/scoggin-...ter/sd8060arpm , because it gives you everything you need to install Vortec heads on a nice build.

But, Vortec heads REALLY need a dual pattern cam, as the intakes flow very well, but the exhaust is no better than "regular" small block Chevy heads. If you want to stick with Lunati, then the 10120702LK would probably be a good choice. The 10120703LK would pack a little more punch. Either would work well with the heads/intake in that kit from sdparts.

Those are decent pistons. You may need oversize version, though, as those old blocks rarely have useable stock cylinder bores.

That Holley carb is a good one, but since it doesn't have a choke, it'll be a bit cantankerous for several minutes until the engine warms up. By "fuel rail", I assume you mean a dual-inlet fuel line. You will also need a vacuum/mechanical advance distributor, as your TBI distributor won't work properly. For spark plug wires, I found the Summit brand universal HEI wires worked very well.

A stock TPI in-tank electric pump with a return-type regulator would feed the above fine. A Walbro 255 is a popular upgrade.

Headers are practically a must. Stock LO3 exhaust manifolds are terrible. Do you have someone who is giving you a deal on custom fabricated headers? Hope so, because labor is usually a killer for custom exhaust.

You can make a dual snorkel air cleaner out of your LO3 air cleaner and another snorkel from a junk yard air cleaner. The problem with an open element is it sucks in hot air from around the engine. But, many people use them, so it's not like it's a deal-killer.

Oh, you'll need a different flywheel as well. Get one for an '83-'85 f-body V8 T5 application. You can use your '92 clutch with it.

And take it easy on your T5...

 

thanks for the valuable info, i really appreciate it. I'll discuss it with my mechanic and get back to you.
