To high for me maybe $25-$50 and I'm not expecting anything from the saws that are being sent to me that was just discussed.

What is your time/ expertise/ Investment worth? How much actual time does it eat up to set up and make a pull?
 
Top end is totally different design. Quad transfers and long entrances that start near the front of the jug outside of the actual cylinder instead of the two shorties on either side like a 460 has. And a weird little aluminum hard-on in the crankcase that should kick extra lube to the wrist pin. Some minor differences in the carb jetting too but if you were locked in a room feeling around in the dark you would call it a 460.

Be careful what you say around these chainsaw pervs...they will be asking for pics and stuff.
 
What's going to happen when two different builders build the same saw and compare???? Someone's feelings will get hurt...

I'm sure AS Members that have ported saws know these builders produce quality work. Competition usually results in better products, better performance, in the long run. Consumer report has been doing it for years.
 
Hey Keith, wait for the results from your ported 461 and my ported 660. Winner takes all, loser pays for the dyno testing! LOL
Deal! If the ported 461 makes as much hp at 10000rpm I get ur 660?? lol?? Im just kiddin I aint makin that deal!!
 
My big Dodge Cummins has been on 8 different dynos. Prices ranged from $50-$110 depending on type of dyno.

My truck spends about 20 mins on the machine.

I agree with randy, $50 sounds pretty good for some pulls and a colorful graph to brag to your buddies.

A dyno day would be cheaper as lots of people are there with their saws to win bragging rights in person. :)
