need some info on strokers

Well, you could just get a short block mailed to you from DSS or CHP. They are very reputable. As far as installing the engine, if you have a cherry picker or are willing to buy one its do able in your garage. Basically its just making sure your connecting everything correctly when you get done. Pulling the old one out and dropping the new one in isnt that bad. Its all the little stuff that gets really tedious and annoying. As far as building the motor from scratch, you are gonna have to make many trips to the machine shop and may need things like dial bore gauges if you wish to blue-print the shortblock. If you feel up to the challenge then go for it, but if you dont have any experience with this kinda stuff you may want to take a class at your local community college first or something. Or if you have someone experienced that can help you with this kinda stuff, ask them. I didn't feel confident building my motor myself as I didnt have the toold for it nor did I have anyone to go to if I didnt understand something so I opted to by a assembled 331 shortblock and not worry about it. Anyways tools will cost as much as assembly labor so if you dont plan to do this often then your gonna have tools you cant use and you'll have used up a lot of time.

With a 5 speed, it is easier to pull the trans attached to the engine. That way you don't have to rassle with getting the pilot bearing to line up with the trans input shaft while the engine is slung from the engine hoist.

Many auto parts stores or rental equipment places will rent you a cherry picker. If not buy one used or from Sams's club - they have a better price than you will find anywhere else.
