416 1/4 mile times

I reckon there's enough hp there from your specs (430 conservatice guess)/3350 for you to run around 115mph on a good tune, if it hooks and goes in the 1.6's for 60fts its mid >high 11's. As said it takes time to get the best tune on the day depending on how many shots you get at it and of course the track etc. etc., that 750 Eddy is your weak point though for a max 1/4 time in my opinion, I used to run an 850DP on my 340 with same heads as you and it would go 2/10ths slower with a 750dp, the Eddy is a good street carb, just not for max attack 1/4's......good luck.
Holleys make engines (run) I'm just not a fan. Uneducated i guess. I drive it to work,store, beer store etc. it's just a driver for sure. It hasn't seen the strip in 13 yrs so I'm coming out of retirement so to speak. At least for one night for now.
