When Ted was running my 4-71 motor on the dyno he said it really picked up horse power with one of those 1000 something CFM Holley's. Was a bit surprised. My engine was built to be streetable so its really not built for maximum power.

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Dave,
running the engine on a stand allows time to address any unforeseen issues (leaks, etc) on my time. Running through several heat cycles before hand allows me to change from break-in valve springs and rockers to the performance parts and re-torque heads on my time. Also get in the ballpark on jetting/timing on an all new build that I am not sure what to expect. Preliminaries will be done. Rings will get broke in on the dyno. Dyno time isn't cheap.
Thank for your interest,
Dean

 

Why are you not using the dyno to break in the engine? The dyno can load and unload the engine to perform break in. Or at least my buddies superflow dyno has a program to do that.

OOOPS  I guess I should read the post title

Dean is that a 471 or 671?

Rono,
I plan on using an engine dyno after breaking in cam on my run-in stand. Plan on trying several different carbs and drive pulley sizes on dyno. Thanks for your interest.

 

Will you be using an engine dyno or a chassis dyno?

RB,
thanks for the invite. I just got the approval email from Byron for the glory days race for my 56.
I broke it there last year and it hasn't run since. Probably good that it's a long ways off. lol
I think I will use G&S Dyno in Shafer MN for he Y-block. He is closer and I hate driving in the cities...

 

Dean  Can't wait to see that on the track.  Are you in at Glory Days?  You need to hang with our Y block shootout group now.. You will be one of the big dogs with a blown Y block.. Are you going to dyno at R&R performance?

THANK YOU GUYS FOR YOUR INPUT! Since I currently have the blower on a stock engine in a vehicle now, I plan on starting and breaking-in this hot engine on my run stand with just a carb and stock lo-lift rockers. After a lengthy run-in and re-torque, etc. I will install the blower and hi lift rockers and run it again before taking to dyno shop. I do have a boost referenced carb to switch to after run-in. I am running a dura-spark converted distributor curved for blower use. Any other needed gadgets will be added as needed. My shop is currently closed due to -25* ambient temps.
