I want to buy the latest model sb chevy I can find that will work easily with Red.

I want to be able to bolt on a Performer intake.

Are the later model, distributor-less motors stand alone or do they require the ECM to work?

When did they stop using the HEI?

When did they start using the single serpentine belt?

They definitely need the ECM.. this controls the Dual-fire coil, fuel regulator, throttle position sensors, you name it!

<BLOCKQUOTE>quote:</font><HR> When did they stop using the HEI? <HR></BLOCKQUOTE>

It was used until 1999 as far as I can remember. When the new 327 V-8 came out and the 350 Vortec's were canned, then they started with the dual-fire coil, rather than the HEI system.

1988, when the Throttle Body Injected 350's were implemented.

Your best bet is to find yourself a late 70's early 80's 4-bolt main 350. Otherwise, get yourself an 84-86 350 2-bolt main. The fuel injected Vortec 350's of later had different heads, and the intake plenum angles were different than their carbureted brethren. You'll have to find a carbed model.

Then, I need to buy the serpentine belt system and put it on a GM crate motor? I would expect this to still be cheaper than rebuilding the 401.

Also go to GM's website. You can buy a 350 horse 350 complete with MPI fuel injection for 4,000. This might seem like alot of money but consider that it is fuel injected and comes complete with a wiring harness, water pump, valve covers ect.ect.ect. A regular crate motor from say Pep Boys or other chains will not have all that stuff and still cost you a grand.

Jeepfreak is absolutely right. The only thing that I saw that was a little less expensive, there is a guy that pops on ebay every once in a while with a complete 350/700 r4 that they are cutting out of a wrecked Yukon/Tahoe/Burbon. He sends you the whole thing (Including part of the frame and the exhaust from o2 sensors forward) went for about $3200.00. You could do the earlier 350 and then upgrade to the edelbrock TPI, but that's $1900.00!! If you're going to go carbed or TBI, just stay with the AMC motor, you won't have to mess with the tranny or motor mounts and you can still have one heck of a performer. I personally am dropping a remanufactured 360 into mine with the Edelbrock package and I'm right at $2000.00, for another $700.00 i can have the Holley projection (fully programmable, unlike the stock Chevy TBI) and gain all the reliability and gas milieage. Just something to think about.

Ok You have many ways to go with a GM motor.. Edelbrock does offer an intake for the newer Vortex heads. takes a single 4V carb... you can drop the old HEI right into it and run it... you can also get the holley Projection and intake from holley and run that... You can also get the Stock truck 2V intake Throttle body and go that route, some company offers a Aftermarket puter that will run it, comes with wire harness and good instructions. You can run a TH400 or a 700R4/ 60LE with a new fly by wire transfercase, GM used all kinds of Tranfercases including the NP231. If you grab a 231 you can put the Dodge one ton chain in it and you will have all kinds of Transfercase to handle all the power you can make. if you use the 400 you can use the 203, 205, 208...ETC... if you want heavy duty 203 or 205.....

Gee I could go on for hours on this line....

I see a lot of adds in Hot Rod and other mags for brand new GM Goodwrench 350s for $1400. These are complete engines with manifolds and a waterpump. They are listed by GM as replacement motors for '84 and earlier vehicles. I believe they are rated at about 200 hp. HotRod also recently had an article about how to upgrade these engines to TPI induction using '90-91 Camaro parts. If I still have my rig a few years from now, I will probably go this route instead of rebuilding the 401. Also, use of the Chevy small block opens up a variety of OD transmission options.

Uhh... 231 with V-8 power isn't a good idea.... 241's were offered behind the 350/700R4 or 4L60 combo?

Remember..

700R4 - Based on the TH350 design Hydraulic Overdrive with one electrical wire to disengauge the OD via the brake light wire.

4L60E - Electronically operated 700R4, more wiring, ECM

4L80E - Based on the TH400 Design, Electronic Overdrive, more wiring, ECM

231's were used in XJ's, and small Jeeps, also, Dakota's, S-10's, and Ford Rangers. Mainly with 4 or 6 cylinders.

241's were used behind the V-8's... K-1500 trucks, Z-71's, Dodge Rams, Ford F-150's.

It's all about input max torque!
