409 Stroker Build

[GBRG07]

I have learned over the years that torque is the fun number and stroke is torque and cylinder heads are horsepower.
I had a 565 Reher Morrison engine in my old Nova drag car 2700 lbs. Broke the crank and put a 583 Reher short block under all the same parts. Same heads cam etc. On the dyne it made exactly the same HP 1017.
On the track that 1/8 more stoke was worth a .10 8.34 -8.24
So when I think about buying pistons and rods for my 409 I think why not go to 4.00 crank or better yet 4.25 especially in a heavy car.
Just my .02

Mark... I got my 9" from Johns just like Brian and Brian said... mine has 31 splines... it was at my house in 3 days after I ordered it...

I run a 9 inch with 35 spline axles with a detroit locker it's been in there since 1997 with no problems knock on wood

I have a Johns 9 inch in my car with 31 spline axles. No problems so far.

All this is great information.
I'd like to run in the mid 11's, even though I'm sure I will be able to go faster.
Thanks a lot.
