350 small block questions
 

I have a early 70s 350 four bolt main does anyone know what if any "modern"(80s or 90s) four or five speed manual transmissions would be compatable. I have an older four speed and the bell housing that I am putting on it. I am just trying to find ways to improve gas mileage and was hoping the modern gearing would help out. Thanks in advance for any help.

The newer stuff is mostly VORTEC engines. Generally not compatible with the vintage L-block
stuff.

The good news is you've got junkyards full of old stuff, and they have "interchange manuals" which will help guide you in your search, if you don't want to take advantage of the massive aftermarket in L-block(or in the case of a 4-bolt main, more than likely LT1) drivetrains and parts. Happy hunting.

Thanks Rivereye
 

Thanks for the info I will do some more research. I may eventually switch to an automatic either a two speed powerglide(if I can find a good one) or a 700r4 which you can find just about anywhere.

I'd research some other forums, the good news is if you have a block with a 4bolt main in good condition, you have a solid foundation for a strong build.

Get a variety of opinions, and don't forget, those large auto recycler yards can not only point you in the right direction with the interchange manuals, they can usually turn up some fresh stuff at rock-bottom prices.

the engine,the truck
 

Yeah the engine is a fresh rebuild bored forty over because there was a groove in the cylinder wall. The engine has not been put in or fired up yet so I am excited to get it in and started up shouldn't be much longer now. I have a thread in the full size trucks forum with some pics of the truck I am restoring.

thanks 1Gary
 

looks like tci has some good stuff if money was no object some one could get carried away and really go for the gusto. Thanks for the source though I was just trying to see if there was any stock or stockish trannies from the modern era that would bolt on. That way I could maybe find one at junkyard to swap out. I am not against staying with a manual a five speed could be nice for better highway mileage.

I don't know where you live, but usually around any large city you've got 3 or four major
auto recyclers. You really need to get them to check their interchange manuals for you.
Save money, get stuff. ROAD TRIP!!--WOO-HOO!!

where I live
 

I live about 50 miles west of St.Louis,MO there are some ok resources here in Missouri it just seems that classic truck parts are becoming more scarce. There is a u-wrench it(now called pick-n-pull) in the city that is rather large and has decent prices. A good road trip is always a fun time.

here is a pic of the engine
 

Finally got to take it off the stand and put it in the truck still some work before it can fire up but glad to have it off the stand. We just sat the valve covers, carb, and air cleaner for the pic not actually bolted down yet still looks good.
