Re: Stocker Crankshaft Heavy Metal
An externally balanced motor like a 428 FE needs weight added to the rear crank counterweight to make it internally balanced. There are other examples as well. This is legal but you may have trouble with a light crank with added heavy metal being considered a "normal" balance job.

Re: Stocker Crankshaft Heavy Metal
sent a 66 289 out for an overhaul and balance (nothing special, just a stone stock rebuild)
as we don't do that at the shop and it came back with a swiss cheesed flexplate and mallory metal in the crank... what's a "normal" balance job? |

Re: Stocker Crankshaft Heavy Metal
In Stock Eliminator, it is legal to use heavy metal in the crankshaft in order to internally balance an externally balanced engine. Other than that, heavy metal is not legal, as it falls outside of the "normal balance job" rule.

Re: Stocker Crankshaft Heavy Metal
Tom,
The only way your 289 flexplate should have been drilled is if was previously a zero balance flexplate,like a 300 six. You may have to fill in a previous hole in counterweight of crank but not with heavy metal. Mike Taylor 3601 |
