Knife edge crank
Has anyone here had there crank knife edged? I called a few local machine shops to get prices but the closest i coudl get to a bal park figure was 60/hr plus balancing but he wouldnt give me an estimate on hour many hours it would take him. I would like to have this in my motor but with out a clearer i dea of cost i cant plan on it any help would be much appreciated thanks in advance Matt Manglos

Crank scraper and windage tray are better investments than knife-edging unless you just have to have that last 5 HP for about $100 per HP.

I agree with above 
Yea the extra 5HP that u gain is hardly worth the cash, but then again it is a 5hp that increases effency and does not effect emissions, of coarce the other changes also do the samething in helping just they help more and cheaper.

I had one done it was $675 with a balance job at the same time. The crank I had done was made by L.A. Billet and worth a lot of money. If you do that to a stock crank you will have a hard time balancing it. The best way is to get a crank with the counter weights designed for it.

Here is a picture of a nice lightweight crank with 3.800 stroke, the crank is 44.9 lbs this short block is going in my Camaro.

A new SCAT crank with the knife edge cast in is cheaper though...

I had 70 to 80 bucks in heavy metal alone add'd to my stroker crank (not counting labor on it and it weighed 55 lbs before) when I had it balanced. Before I also had the 400 Eagle turned to 350 mains cost me another 100 bucks.
