Carborator
Hi
I have a 1969, 427 with a Edelbrock torker II 2-0 intake manifold.
I have tried with a Holley carburator 4779 750 DP. ( double pump )It was a little to "violent ". Not easy to start and used a lot of fuel.
Do you have any proposal. Holley or Edelbrock, and what type.
Mostly street, but I like to drive fast.

Save your money and tune the 750Holley, no reason a properly working carb would make a motor hard to start and if tuned with a wideband O2 you can get good mileage from the carb 
Only reason I would change carbs if it is a 20 year old gummed up pos

I'll tell you what, those new vacuum secondary Summit carbs are pretty darn nice for the price.. I bought a BG Mighty Demon 750DP and paid over $600 for it and there was no performance gain over the 750 Summit carb.. To be honest, the off idle response was just as good as the BG and it pulled hard when I needed it.. I purchased the BG in hopes of a performance gain but there wasnt any.. The Summit carbs are under $275 NEW and I can promise you any performance street car I own in the future will be wearing one.

auto or manual trans.
auto trans will normally respond better to vacuum secondaries.
that torker manifold is supposedly not the best in the world either.
granted there arent many square bore manifolds that will fit under a stock BB hood but even the rectangular port LS6 intake will,so i have heard, perform better than the torker.
i use the annular booster 750 speed demon on the ls6 intake on my new 430hp/500lb/ft crate 454. it all fits under the stock hood and if i am leaving any hp behind it aint much. whats nice is the demon was taken from box to motor, out a half a turn on the idle screws and a few jets up all around and i couldnt be happier.

Just today I spent the better part of the day doing the very same thing I mentioned. Now I'm getting "miles per gallon" instead of "gallons per mile".
