Subject: Few Pics of the progress by rklessdriver on 2009/5/28 22:28:51 I've had a few people that were really interested in my 44 lb pendlum undercut crankshaft. Aparantly no knows that someone makes such a crank for 1pc rear seal SBC's. I really couldn't take any pics before with the motor running in the car and the pics I orginally took I couldn't find. My little mis-fortune gave me the chance to take some pics for you guys. I had this crank made by Eagle. It took me a few mins at PRI 2yrs ago to get them to agree to build ONE for me. It's one of their standard forged 4340 light weight cranks (normally 51 lbs) that has had the extra machining steps to to remove weight in the non critical areas. Total cost was $809.00 and it took them 2 weeks to build it. Eagle will now do this weight removing undercutting to any of their crankshafts by special order. Wouldn't you know I found the orignal pics.

For some reason they are all blurry. My brother ain't the best at taking pics indoors with shop lighting and all but here anyway....

On a dyno (HP wise) I can tell you it's worth excally 0.0 HP... but on the street, the throttle response and way it gains RPM is a totally different animal. Of course you have to have really lightweight rods and pistons to compliment it. These cranks are pretty common place in oval track racing (where allowed by the rules) but it is not something you see everyday in a street car due to availibility and cost. Just thought you guys would be interested as a well priced option now exist for you. BTW the engine is now completed and next weekend it should be back in the car again. Will |
