Speed density years?

What years were the speed density systems on the 5.0's? The reason im wondering is to find some motor upgrades for my 86 f150. There are almost none available for that year but if i goto an 88 there is more options available. So if the motors were pretty much the same from certain years, im guessin i should be able to take the parts off of an 88 and fit em to my 86 right?

Most of the '86-'95 truck 5.0s were SD though there were some beginning to appear as early as '93 or '94. What parts are you considering upgrading?

As you have probably seen from my other threads, im redoin my motor. cam, headers, porting the exhaust on the heads and port matching the intake to the heads with a 1" spacer. thats most of the work besides a few things here and there like underdrive pullys, and a throttle body spacer.

Seriously man.. don't waste your money on TB spacers and pulleys, they won't give you anything but a lighter wallet and a drained battery.

You can do all of those modifications, with a speed density friendly cam, but it'll need aftermarket tuning.

The difference is the 86 had crappier heads and a 1 year only air cleaner assembly. You need E7TE heads.
