Stroker Kit? Explain to me?

Someone explain this to me.....what do Stroker kits do? As much info as possible apprecaited as I am not very good with cars. Thnx

Stroking makes your engine bigger or smaller by changing crank shafts.
We put modified 400 cranks in our 350's along with some new pistons, and we turn our 350 into a 377.
We make them even bigger( a few cubes bigger) by over boring the cylinder bores.

actually you put a 400 crank in your 350 block(plus bore 30 over) to make a 383.
350 crank in 400 = 377
longer stroke = more " pushing" down on the crank = more torque
and horse plus the extra stroke also causes compression to go up.

I have a 305....what kind of kit would I want (links?)

Would it be "safer" to stroke my engine or only upgrade the heads/cams....or just do headers/exhaust

which are safer, which are more cost efficient, and which give the best performance gains...and what combinations will produce the most power together?

thnx in advance i know thats alot

By the time you pay for machine work and the stroker kit, a 335 stroker (305 block) will end up costing the same as a 383 stroker including the price of a 350 block, and it will make more power.

Unless you're really married to your 305 I'd advise to just find a bare 350 and go from there.

To answer your other questions... :)

Start out with exhaust. Get the stuff leaving the engine before you worry about getting stuff into the engine. Good headers - SLPs are evidently the hands down best if you can spring the price, I've also had good luck with my Hooker's - a nice 3" cat and catback. Rear end gears are a great choice, I'd do 3.42s if you have a A4, or 3.73s with a 5-speed.

Then you can start too take a look at heads/cam/intake, and eventually a new engine. Get the smaller stuff taken care of first though, and see where that leaves the old bank account :)

The term stroked or stroker used to mean increasing the stroke of a crankshaft by welding up the rod journals, tossing it in a crankshaft grinder and grinding the rod journals offset from their original center. This wasn't a cheap process, but there weren't many other choices.

Today, stroker usually means simply putting in a crankshaft that has a longer stroke. A small block Chevrolet 327ci, in these terms is a stroked 302ci. A 350ci is a stroked 327 or a really stroked 302. And a 383? Well, take a 350, and put in a 400 crank.


A 350 has a 4.00" cylinder bore, and a 3.50" stroke
A 305 Is Worthless
