Ok, no biggy. Is the lack of quench what makes open chambers poor for high compression? I've had a tough time finding a very detailed expansion of that

Hey guys, I've heard a thing or two about how you shouldn't go high compression with open chamber heads, yet i also see guys having done just that. It just so happens that my 440 has 452 heads with 2.14"/1.81" valves, pocket porting and blended bowls, along with gasket matched intake runners and...

Thank you guys! Hopefully this setup will work well on the street, i am trying to keep compression where i can use 93 octane fuel and not build it too hot for the cast crank. I've read that the factory bottom end can survive 600hp, and while that would be awesome i don't want to push the limits...

Hey guys, I've decided to rip into my 440 and make it what i want. I have decided on having my 452 heads worked a bit to save a big chunk of money as opposed to buying a set of Indy heads, and i have a weiand hi-ram intake currently running a pair of Holley 600 carbs. I will be switching to...

Thanks for the replies guys! The trans and rear end are the originals, but the original owner used the car as a drag car for most of its life. The trans is built, he put moser axle shafts in, front disc conversion, mini-tubbed the rear, moved the battery and washer jug into the trunk, removed...

Hey guys, my 67 barracuda currently has a 440 in it, super low compression with a low lift/high duration cam and a tunnel ram with a pair of 600 holleys, 727 trans and 8 3/4 rear end with 4.10 gears on a spool. It is well tuned and is a super fun car to drive. I am going to be building the...

The less i have to dig into it the better, I'll only be spending more money the further i go, be it by necessity or by my sheer desire to buy new things. If i can achieve 600-ish hp safely with the rotating assembly and cam that are in it then i will leave it alone. The engine was rebuilt just...

I found the stamping number on the block and the casting number on the heads, it's a 1978 440 with a cast crank and 452 heads. Now a background on the car: it's in a 1967 barracuda that spent most of its life as a drag car. It has a 8 3/4" rear end with 4.11 gears and moser axle shafts, the...

Thanks for the advice guys! I have stock cast iron heads at the moment, I'm not sure what the casting number on those are either but i was debating whether or not to have some serious work done to them or if it would be worth getting a good set of aluminum heads. I've looked at some edelbrock...

Hey guys, I'm planning to supercharge the 440 in my '67 barracuda, and I've got a couple questions before i go ahead and start ordering parts. First off, how much could the stock crank handle with a 6-71 or 8-71 blower? I'm assuming it's cast because i don't know the serial number on the block...

Would a progressive linkage be better for the street? I have read so many different opinions that conflict each other it's getting confusing. Someone said a straight linkage with heavy springs in the secondaries is the best. Will having dual carbs affect the operation of the vacuum secondaries?

Thank you for the replies guys, i ended up picking up a pair of 1850-2 600cfm holleys, and I'm going to swap out the secondary metering plates for metering blocks so i can adjust the jets. Would it be worth it to swap the secondary diaphragm spring covers for quick change ones to speed the...

Ok, it appears the 600's are the way to go. Does anyone know if the two 600's i have would work if i set them up the same? Or should i match one of them to an identical one?

Hey guys, I am putting together a dual quad tunnel ram setup for my 67 barracuda. It has a 440, bored 0.030" over during the rebuild, with stock iron heads that have been well ported and have some slight bowl work, a .488"/.498" lift 298/303 duration (224/234 @ 0.050") cam and has a 10:1...
