Dyno results and track times will be the same as a c headed combo with a c upper.

Does anyone have a c head swap and nothing else done to it and have some dyno numbers?
I'm so lost... Lol ok so this might be a noob question.. What's the differents better the c upper and a b upper? The SN95 cobras came with b heads right?
Yes 96-98 Cobras had B heads.
so... when i bought the mach 1 intake it came with a spacer. is it something i should use or sell? if i used the spacer and adapter it might not clear the hood right?
I currently have a 98 cobra, just got done rebuilding the motor with forged parts and C heads with 01 intake, but I like the looks of the old B head intake better as well. I'd be interested in one of these (seriously. would pay up front) if it won't cost me any power losses. Its stroked to 5.0 with 8.5:1 compression, built for turbos later on, I'm almost thinking there could actually be a slight horsepower gain with this setup over the 01 upper if under boost as well. Add me to your list of people interested, I'd like to see some numbers to back it up, if there isn't a big power loss I am in for one.
I dont think you could clear, but it wouldnt hurt to hang on to it to try. How thick is the spacer?
Do you have any pictures looking into the bottom of the upper? So we can see how the inside edge meets up?
I also thought the C heads were COP, but you've got coil packs and plug wires...
im also considering buying a regular v6/gt hood. Use the spacer, and have the upper intake stick out of the hood. I'd have to cut the hood of course. I haven't measured the spacer but its not much. Less than 1/2"
Valve covers all fit between 96-04. So it really just depends what you want to go with. My 97 cobra has b heads and uses coil on plugs
I knew they fit on the heads, and I knew there was a COP conversion for the B heads, but I didn't realize you could use the B head ignition on the C heads. I thought there was a fitment or oil seal issue. Learn something new every day.
if i remember correctly i think they are on page 3 towards the bottom
fitment of what? Spark plugs are different Motorcraft part numbers between 98 and 2001, but other than that everything matched up
All 4v valve covers can be used on any 4v heads.
That would be hideous; don't do it.:nono:

There would be no benefit in using the spacer with the B upper.
