@@servediocylinderheads It works better if you turn it on.😁👍 Not sure if you seen my last comment on the video before this one or not? It's about your friend's channel, he has it setup as a chillins channel.(Spelled it that way in case the tube disappeared that comment on the other video, you can't even write that word these days.🙄) Setup that way it is useless to subscribe because being fully grown I won't get any notifications from him. You post your videos right, maybe you can tell him how to not have his channel for chillins?
I had a little chuckle to myself when you mentioned pulling it charge during overlap. I pay a lot of attention to low lift flow, because I believe that it determines the high lift flow rate in the running engine. The more charge that you can get moving sooner, the higher the final velocity will be. Well, that's my theory anyway
Hi Charlie. That was quite a big gain for seemingly little work. You said that you just basically cleaned up the port and narrowed the guide. Would there be situations where you would have a throat that is not round? Maybe wider on the sides and back but narrower or less removed from the ssr area? Thanks Andrew
@@servediocylinderheads I've had one like that too I did alot of Quadrajet tuning and drilling to make it idle smoother compared to an engine with a Holley that was built the same but I also did some slight porting on the 461s. I did cheat some and used Rhoads lifters. My idled like a torque cam and the other was choppy . Same cam and compression both were 327. It made alot more torque. Than the other.
@@servediocylinderheads I forgot This was back in 1984 I did a 3 angle valve job on a fairly new Souix valve grinder at the vocational school I went to. Boy that tells my age. lol
@@servediocylinderheads At close to sonic speeds, the rules of air are opposite than at slow speeds. Expansion accelerates, contraction slows down with high speed flow. At low speeds, contractions accelerate, and expansions slow down flow. At low lifts the exhaust is as fast as it's going to get and it's the most likely to choke, and change the way it behaves than at higher lifts. Maybe the lower lifts from the exhaust tell you more in terms of what will happen during overlap.
