Have them make an aluminum version while you're at it.

looks like its only days away.....this car will probably hit close to 500rw once they put on the ls6 heads

I know quite a few 396 cars running normal base on there cams

The rods are a place I don't like to skimp so picking out a rod specifically designed for stroker clearances just wasn't in the cards for me. You have to weigh in your ultimate goals and making sure you leave yourself room to grow when making those decisions. I also think the basis of the base circle of the cam in this particular thread is a bit overrated. Whew...say that last sentence a couple times real fast

I would tend to agree with bobby here. its not that the "right" rod for a 396 will give more cam clearance. There are "stroker rods" that will give more clearance, but generally at the sake of money and strength.

Besides, I dont think the diff between a 1.0 and a 1.2" base circle is all that big of a deal, The LS1 is MUCH bigger. not .2
