Call AED, tell them what you got. Buy what they recommend. I used to recommend quickfuel, but they got bought-out, and i have no first hand experience with the new company. They will both be holley style carbs.
A note, the "hy-lift" johnson lifters are not the same as the original "johnson" lifters you should use. The real johnson, made in usa lifters are found in the link below. There was/is some kind of legal faff, and the hy-lift lifters are not the same as the original johnsons, now a completely...
I have both set-ups. I have an internally regulated performance mechanical pump on my 505/512. With an Quick fuel SS830 carb with no problems (with the factory 5/16 fuel line feeding it!) And i have a 496 chevy with an electric pump feeding the mechanical pump to an AED 950 carb again with no...
Agreed, changing to open chamber heads, aluminum or not, will lead to lower compression and performance. If you can have hardened seats added to the closed chamber stock heads, you should be good. I suspect that you will rapidly run into diminishing cost returns for any additional...
Also remember aluminum allows for higher compression ratios on pump gas. Although if your motor is stock, you will not have an issue. If you are going to step it up in the future the heads would already be good to go. I think the stealth heads had any issues worked out long ago. I ran mine...
They credited me the purchase price back on it, but not until i sent it back to them, i bought the mechanical one because i didnt want to be without my car while they made a determination. I went against my instincts when i bought it, i always have run full lockers. Zero maintenance and...
I had heardened valveseat 452's i couldnt give away from my 66 440. It is really hard to match the performance and value of the 440 source aluminum stealth heads. Just paint them blue and no one would know the difference except your back muscles.
I broke the detroit helical one. I talked to randys ring and pinion who initially said it would be fine in my car. After it failed open, they said they should not have recomended it. I replaced it with a full detroit mechanical locker. It has been great, see my previous posts regarding its...
The green bearings are fine, and in no way are they lighter duty, or the "cheap" way out. They guy in the mustang has no idea i am running the green bearings.
I have the full TTI system, headers and all. I bought a set of pre-made, pre-bent lines from one of the places recomended on here. I used my custom "hand wrench" to make them fit without lifting the motor, taking off the headers, or any such nonsense.
