For example, lets say an lq4 408 stroker crank and shorter rods and factory pistons to have the factory piston height at tdc. For a na build on low mileage motor, it would save boring block and new pistons or would a shorter rod bring the piston down too far at bdc?
and will crank throws on a 408 interfere with a fbody ls1 oil pan / windage tray? im guessing its not 408 on a standard bore...
Also the stock piston height with more cubes would raise the compression ratio also correct? without having piston come any closer to the head?
I dont reuse toilet paper but i like cheap...

Put it all together and let us know would ya...

You need longer rods in a stroker engine so the pistons clear the crank. Your scenario will not work.

^ what he said. the crank counter weights will clash with the piston at BDC with that scenario.

Yep, it's gonna leave a bruise.

You need everything to match: crank, rods, and pistons. Stroker pistons have the wrist pin boss located differently. You also need to know in advance how much your cylinders will be bored. For a 408 you need to bore .030". You can also go .005" (403) or .010" (404) if you want. A stock 4" bore with a 4" stroke is 402 CID. A decent rotating assembly will cost you at least $1800 new. Sometimes you can find good used deals in the classified ads section.
