so, what makes it a motor a 383 stroker?



because for now on this is a stock firehawk with exhaust. there is no freeking way it has a 383 with the dyno #'s as low as they are('stang-dyno jet, 295rwhp) and low 14sec., 1/4 mile times...

i was checking out LS1tech... this fooking bird isn't all that far off any other stock Hawk, **** me for saying I have a 383, and **** the guy who "built" it!!! https://ls1tech.com/forums/lt1-lt4-modifications/303172-lt1-dyno-archive.html

Stroke of the crank shaft and over bore of the cylinders. ie. 4.030" bore with a 3.75" stroke crank = 383

And, just to put in my 2c, the 372 is 4.125" bore (400 motor's stock bore) with the stock 350 crank stroke of 3.48".

Anyone ever tried running a 265cid crank 3" stroke with a 4.25" stroke (427 sbc) for 341cid high reving beast?

I have seen a 302ci LT1 once. 265ci LT from a Caprice and a 3.48 crank makes one hell of a high revving little LT1.
