im thinkin on making my spare 3sgte a stroker input please...

how do you build these with 5sfe... is it the 3sgte block, rods and pistons w/ a 5sfe crank shaved down?

I think Junior hit this one on the nose. lol. The 5s is a 2.2 liter and the 3s is a 2.0 liter. Go get the stroker kit. Even if you bore out the 3s block to be a 2.2 liter, the 5s rods aren't going to hold big amounts of boost.

Junior and yourself actually have it the hard way. Not incorrect... but just mis-interpreted. There are versions of the 5S block that you can simply mate up the 3SG head to. Regardless of bore differences, so long as a proper head gasket is used, like an overbored 3SG gasket, it'll be fine. You can't bore out the 3SG block too much, nor can you drop in the 5S crank without some machining. I doubt the 5S crank and fit in the 3S block without some machining. From there, even with the stock 5S bottom, mild boost can be applied so long as the tuning is good. Stroking with the 5S bottom-end will be a whole lot cheaper than buying an aftermarket stroker kit for the 3SG.
