So...tighter is better???

 

Tighter?thats what I always liked....Oops your talkin rods.
Yeah ,but not too tight either,stock spec is .005-.012,but for performance a little looser is desired.

My goal is to dip into the 11's. Hopefully I'm heading in the right direction.

11's? Easy with that combo.

 

What size journal would be a SBC large journal be, 2.125?

 

Thanks, I hope you're right! and if it don't,,,,I will spray it more:bla:

 

Is it bad to off set grind you crank to use BBC rods? Its seems like people talk about it not being a good deal. Any reasons? Thanks Gary

 

I can't think of any reasons not to,BBC rods are less expensive and you get more cubes,make sure the filets on the crank are properly done and your good to go.done lots of motors with this combo.The CSB large journal rods are also a good choice,482 and still a stronger choice because the crank isn't turned as much as a 494.

Thats what I was thinking, More cubes, Cheaper stronger rods, And the crank is stronger that with the 494, It sounded like a win win to me, Thanks Gary

 

How many cubes can you get useing BBC rods? Also how much do you have to take of the crank? Thanks Gary

 

Your at 470 + depending on your overbore.The BBC is 2.20

 

Is the thickness of the chebbie small and big block rods, the same as the big block buick rods? So as far as machining goes, I would really just need to have my crank offset ground to the bbc journal diameter, and the radius matched. Is this a process where it's best to send crank/rods/rod bearings to the machine shop so everything can be checked? Might as well have it all balanced too I guess.

While you're in there... ou:

 

You guys were saying that if you stoke your crank you should girdle it, If you girdle it and fill it how much horsepower can the block take? Thanks Gary

 

I dont have a girdle on my 494,but mostly street driven.


Thanks

 

750hp +.Our strokers are all 720plus,but we "stop" em back for bracket racing
gary

 

750 is about it on the block?
