Looks sweet, but how did you bend that lift plate. Have put mine through hell and still looks the same + a few scratches.

Re: It's finally in...
holley 3310 isn't a double pumper carb, and a single plane intake would want a 3500-4000 stall typically as well.

Re: It's finally in...
Thanks for all the comments! Put alot of time into the car so far, can't wait to finish it!
You are correct about the carb I meant dual feed not double pumper, the single plane is on there for now, I got it for a steal. I will probably end up selling it and replacing it with an air gap though...pretty simple to swap out after she's running

Re: It's finally in...
Haha funny story, the reason the lift plate is bent like that is they went to pick up an engine for the late model from the builder all they had was a truck with a hard cover on the bed so in order for the cover to close they bent the plate
I didn't install the engine/tranny with it either...I was going too but was kinda leary with having the vortec intake. Trending Topics
