I’m looking for some advice on tuning my Holley Double Pumper 850 on a fresh 440. My issue is with the primary transition from cruise to power. As I give minimal to heavy throttle the engine is leaning out to the point where I get lean surge or feel the power of the engine reduce. My AF...

Anyone that uses a purchased torque strap, does it provide any dampening for vibration? Or, did it introduce any vibration? I had a set of poly locks from Schumacher but they allowed way too much vibration from the engine into the entire car. Switched over to cheap stock rubbers and the...

I have been running my newly built 440 for a few weeks now. Now that I have the odds and ends buttoned up I want to address a low power surging that I am experiencing. At steady throttle, anywhere from 1200-2000ish rpm I feel a “surge”. I can’t tell if it is a power surge (forward) or a loss...

I had my engine broken in and dynoed just over a month ago. Finally getting it in the car and decided to change the oil. I was surprised to find a blob of fine metallic hair attached to the magnetic drain plug. See pic. It’s very soft and leaves a silver stain on the fingers. Anyone have any...

I’m about to put my new 440 in the 69 Coronet. Is it advisable to mount the 4 speed up first and then angle/lower them in together? As apposed to lowering the engine in then installing the bell and trans from below, on the floor. I have a Harbor Freight cherry picker with a max of 1/2 ton at...

Anyone know where I can find the instructions to install a Centerforce Dual Friction clutch? Amazingly it didn’t come with any nor does their website have any. Just “notices” about certain topics. Good old google doesn’t provide any answers either. Do I just slap it on like a normal...

I’m wondering what people recommend for the input pilot of an 833, bearing or bushing? My specific situation is my crank is drilled to accept an 833. I chose the bearing over the bushing from Brewers thinking that a bearing would be superior. However, the pilot shaft of my 833 will interfere...

Will a Holley Ultra XP 950 be too much carb? I'm putting together a fresh 440, built to make about 500-550 hp, maybe more depending on how good the port job is. Originally wanted to go with FiTech but the budget dictates I save some money here. I'm thinking the 950 would be plenty, even if I...

TTI or Doug’s. Let me know what you got.

Anyone have the scoop on the 440Source Aluminum Water Pump housing? I was speaking to a vendor and he "recommended that I look into it first". I was about to pull the trigger on the pass side outlet version. I have a cast stock one but I figured saving the weight was a good idea, but im not...
