360 on the dyno

I realize that it's not a 450 hp engine but I fail to see your point. I used the holley because it's a known good working carb for break in. It definitely has its place on certain engines and is a great carb. I wouldn't run it on this engine on the street. If we're to use a holley on it, I'd use a 3310. It's not better, nor is it worse. It's just a comparison. Also, I got the carb for free from my uncle that passed away. So I didn't waste all that money on a carb that's apparently no better than an Edelbrock.
The 3310 Holley is a far better carburetor than any Edelbrock or Carter.
There I said it.
I put all my Carters on the shelf 30 years ago after a buddy loaned me a Holley 750 DP.
