Harmonic balancer size SBC
My question is, can I put a 6" balancer on my 350 cu. in. post 1986 small block engine. Right now the balancer I've got is 8 inches. I've heard about internal balance and external balance crankshafts for the small blocks, but how do you tell the difference between the two. Speedway sells a 6" balancer for internally balanced engines. I would like to get a little more clearance for my tie rod on the 29. Right now I've got 1.75 inches at ride hieght and would like to get about 2.50 to 2.75. I hate to buy dropped steering arms if I don't have to. Your expertise is requested. Thanks.
Tomorrow is promised to no one.

All 350's are internally balanced, and yes, you can run a smaller dampener. I ran a 283 dampener on a 327 many years ago. As long as it does the job, size does not matter (so to speak).
There's no such thing as a girl too pretty or a car too fast!
Thanks Rumrumm, I learned something today. And I'm going to show my wife your post about " size doesn't matter" so she can learn to. I'll order the speedway balancer.

And your wife is still not going to believe you.
Just going to add into this that I was a engine tester at Chevy engine plant Tonn,NY.A part of the test was a final balance of the engines while it was on the test stand.The wt on the flex plate(flywheel) was already welded on it on the assembly line and the testers would hammer tab wt's into the H/B'er.This was done on all SBC's and all BBC's too.
yep i had some of them hub pins were you could add to the weight on the damper were there is a ring of small holes on the stock oem damper .thats i very small amount of weight to tune it in on external and internal engines any thing more you have to add heavy metal to the crank
