5.0 with 4cyl tranny

i know it wont last but i recall reading that it'll bolt up is that correct?

If you do a search you'll find some say it will and others say it wont. From just google searches I've done in the past it will work with a different pilot bearing, but you'll have to judge whether or not you want to go by that information.

Yes it will bolt up, no it won't last.

The pilot shaft is too long and narrow. The different bearing will take up the diameter, but not the lenght. You run the risk of destroying the main bearings on your motor. The shaft will most likely bottom out into the back of the crank.

When you start the car and feel a horrible vibration, bingo.

I wouldn't waste my time putting one in. I see V8 T5's for 300$ all day long.

Where do you see $300 t5's?? Around here (northern MN) 4cyl t5's run around $200 in the JY's if you can even find them, from talking to JY's in my area they are hot with circle track racers. 5.0 t5's are generally in the 5-700 range from local people. (local people pretty much equals craigslist for me, since I really dont know anybody else who is into cars and has the parts) I bought a 4cyl t5 for $100, plan on running it for awhile until I save up enough for a properly built v8 t5. Obviously you can find good deals, but as it turns out I wasnt blessed with that skill, haha.

I can find them around 300-400 in southeast texas as well...

I have one in my basement for $300. If its not sold locally I will post it here. Im also throwing in flywheel, balancer, fork.

Longevity depends on how you drive it. Yes, it will bolt up, and no it won't bottom out on the crank. A friend of mine has been running one for 2 years behind a decent 306. Just remember to change the pilot back out before you would try to put in a v8 t5 down the road. Also if the 4cyl is a world class, you can use it for a core to put a nice gear set in after it's shot.

While the 4 cylinder T-5 may appear to be the same, they are not. Most 4 cylinder T-5s received a 3.97 gear set with a .79 overdrive and small input pilot bearing shaft. Four cylinder T-5's should not be used behind a V-8, even when the pilot bearing id is decreased to match. Simply put, they will not hold up. Torque rating ~240ft/lbs. Besides first gear is much too low to be usable behind a high horse power car.

Exactly right, they are not the same. Different gear set altogether that is a wide ratio, Might work nicely if you still have stock rear gears, I think I will try one in my 91 GT, if nothing else to get by. About anything is better than an AOD for this guy, all it has for mods now is exhaust. Let us know what you do, and how it works out.
