Stroker Motor 382.....422 numbers? I was just curious as to what kind of HP you guys were getting out of your motors/setups. In no way am I in the situation to buy or build a motor, but lets see what you got 
Re: Stroker Motor 382.....422 numbers? ARE 422ci
4.075 stroke (4.000 offset ground)
4.060 bore (iron block)
S1 244/244/112
LS6 stage III heads
475rwhp/ 505rwtq
On Speed Inc. dyno, on 28" slicks, converter locked, thru Moser 9" with 4.11's... and with dual exhaust and H pipe.

Re: Stroker Motor 382.....422 numbers? MTI 383ci
4.000 stroke (lunati crank/rods/wiseco pistons)
3.905 bore (LS6 alum block)
R1 cam: 232/236/.575/.578/114
MTI LS6 stage II heads
458rwhp/448rwtq
On MTI dyno, thru Moser 12-bolt with 4.10s, on 245/50/16 Nitto DRs, and with cutout open.
See sig. for rest of setup.
I currently have an FLP 2.5" y-pipe and the LS1edit tuning is still not complete (90%).
Will get a 3" custom y-pipe and wide-band tuning at MTI very soon and expect to make 470+rwhp/460+rwtq with those additions!
This is a very streetable engine that idles very smooth once it has warmed up. Also got 29mpg on a 350 mile trip towards Dallas a month ago, averaging 80-85 mph in 6th gear.

Re: Stroker Motor 382.....422 numbers? John, those are awesome numbers , but i have to say Randy your set up is very impressive also. You are only 15HP behind a 422 stroker. Thanks for sharing the info guys.
