The camshaft is the single most part that determines how the engine is going to run and where the power band is, everything thing else either complements it or detracts from it. Stroking and increasing cubes makes more torque, it has nothing to do with whether an engine lopes or not. Many of these crate engines are cammed more than stock, so you need to be aware, and select what you want accordingly, if it is a daily driver no hot rodding, then go with a stock cam you will have the most engine vacuum for power brakes if you have them or want them, the smoothest idle and the best gas mileage, if you want a little more power then go with some more lift about .5" and keep the duration and overlap down to near stock or a little more, if you want more power then you have to have more duration and overlap to move the power band up the rpm scale, this is where the loping idle and poor low speed operation come in. So my advice is your 347 stroker is probably cammed to produce more hp as such it will never be smooth, but it will be driveable, and if you like the acceleration, you will get used to it. And as the others have stated, you may need a tune-up or have the carburetor checked and or adjusted to get it the smoothest it can be. My 2 cts. Good Luck.
Considering 66
Hi All,
Brand new member here. Please excuse my rookie questions and terminology.. I've been looking for a classic 65-67 for quite some time now and found one I'm seriously considering. It's a 66 coupe with a 347 stroker which was supposedly rebuilt a couple years ago and 4 speed tranny.
Went to check it out and all looked pretty good for the asking price. Upon firing it up, it took a few tries and pumps of the gas pedal to get it started and once it turned over, sounded a bit rough. Took a good 5-10 mins to start idling decently. I'm thinking it's gonna need to be tuned up and carb tuned or rebuil or maybe new. It's a 4 barrel Holley on it now with manual choke.
It was a tough to drive with the 4 speed and me not being used to the clutch which I'm not too concerned about. It did have some hesitation and seemed to choke when pushing down on the gas.
The other issue was the brakes.. Has original drums on all 4 and looks to be original cylinder. When I first started driving and tried to stop,The pedal went all the way to the floor and car kept rolling. I then pumped the pedal a few times and it helped a bit. Still not good stopping power at all. Was a little scary with the brake situation.
So my 2 concerns..
Besides the Carb needing a tune or rebuild. What could I be looking at repair wise? Maybe plugs, wires, etc.?
Brakes.. Definitely want to upgrade to discs in the front and a new, probably dual cylinder. Any other thoughts on this?
I'm all in and know that I will be putting some time and money into this thing.
Thank you in advance for you input!
