Hey, I have an 87 camaro with a 305 4 barrel and t-5 tranny, sometime in the future I hope to have a 383 stroker with a T-56. However, getting the 383 stroker will be a while, will a T-56 still work with my 305? Which tremec should I use LS1 or LT1? Any help or suggestions will be greatly appreciated.

 

any one of those t-56 boxes will work but if you can get a hold of one from an LS1 for a good price, i'd say go with that one and yes it will work with your 305. The aftermarket has a lot of retro-fit kits out there for bolting up a t-56 in an fbody...just do a search and you'll find a lot of info.

 

Ok, With an LS1 T-56, Will it work with a mechanical speedometer?

 

The LS1 T-56 will NOT work with a Gen 1 or Gen 2 small block, it will only work with an LS1. All of the T-56 transmissions have an electric speedometer, you have to either get an electric speedometer or an adapter from Dakota Digital or somewhere else if you want your speedometer to work right. Read the stickty at the top of this forum for a LOT of good info from people who have done this swap.

 

you can make it work with one of these http://www.abbott-tach.com/cablex.htm

 

keith sullivan of speedtek performance put a 98 ls1 6 speed in his 69 camaro that at the time had a 406ci 1st gen sbc. centerforce sells the flywheel, unfortunatly they may not anymore because its not currently in there cataloge. just thought id add.

 

This is true, they will fit with a lot of effort. but if you're going to buy a whole transmission, it's a lot esier to start with one that bolts up with a LOT less effort.
