Yes, Carl... that's exactly what I'll be doing.
First manifold to use, is a stock 63-65 340 HP 409 cast iron intake
Next, will be an Edlbrock Performer.
Then this Speed-port manifold.
The same carburetor will be used on each one. I'll get a baseline with the stock manifold, and get the mixture right. Then the Performer, and see what it wants for jetting. Then my manifol, and do a couple pulls to see what it needs. This is going to be a pretty thorough test, by a highly respected race engine builder. I have a major magazine nibbling for an article on it... but their concern is that they're not in control ( after what we just saw regarding the Hilborn system, I wouldn't let them near it
).
This is why the fair, unbiased results are absolutely crucial.
Originally, I planned on using a 750 Holley. However, I spoke with a tech guy at Edelbrock, and he wanted to see one of their 800 AVS carbs on their manifold. Seems too much much for a small port 49 inch engine
. Anhow, I spoke wih my dyno guy, and he too, thought I should use an 800 CFM carb. He has a "Quck Fuel" on hand, that we can use on the dyno. So, that's likely what we'll be using.
