I'm building up my new rig now that my 4runner is sold.
I picked up an 87 suzuki sami (basicaly for the registration)
I've got toy axles 5.29s and lockers 36" swampers ect...
I'm building a frame for it. :smokin:
I've got an option to buy a 4.3v6 (265hp) out a 97 mercruiser(it is a chevy) this is cool cuz its a vortec but setup to run a carb.Its going to be running on propane (have the parts to do this) but I'm kinda lost as to what tranny tcase combo to run.:confused:
I'm thinking of the 420 tranny but don't know what tcase to run.
I'm on a budget so adapters ect gotto be kept to a minumum.
I need a good crawl ratio so something with a doubler option or gear sets would be nice. thanks :beer:

I am running a 4.3 , 700R4, D18 combo. It did require an adapter, and you don't need ridiculous gearing.:D

I am planning on 4.3L, TH350, and Toyota dual cases.

Unless you want to run something that came behind a 420 in the first place, adapters are the only choice you have...

how about a D300? Or a toy case .

I am running a 4.3 with a 4L60E to Toy case with 4:1 gears. The adapters are spendy though, about a grand. I have 4.88 gears, but probably don't need them. 4.10's would be fine.

don't mind buying an adapter just not going to spend $1000 bucks on one.

I've been looking into a similar project. From what I can tell (someone feel free to confirm or deny this), an SM420 will bolt right up to the 4.3 without any adapters. After that, a d300 makes a good mate and the adapter for the 420 to the 300 can be gotten from Novak (www.novak-adapt.com) for $455.

From the people I've asked, this is about as stout of a drivetrain as you're gonna' get ... working on a budget.

cm "goin' junkyard'n" k

the 4.3 has the same bellhousing bolt pattern as any small block chevy so the SM465 will work also. If you want a heavy duty t-case a NP205 is the strongest out there but the low range gearing is not so good. If you can find a SM465 to NP208 adapter at your local salvage yard you can use the Dana 300 t-case as long as you buy the new input shaft for it from AA for about $150. Cheaper than buying expensive adapters and still almost bulletproof. There is also a 4 to 1 gearset available for the D300 or if you use the NP205 you can run a doubler with all salvage yard parts and the kit from Off Road Design.

thanks thats the info I need.:beer:

the sm420 or sm 465 to toy t-case adapter is only $465 from ott industries. I like the toy case cause it's strong and you can get so many dual t-case and low gear options.

I plan on running a 4.3 700R4 gmNP203 fordNP205 doubler on my toy pu project.
