Thread: Dual Quad Tunnel Rammed 1986 5.0 HO

Tweet

Oh, no, he's at it again.

Working on my second build.

What I have so far:

1986 5.0 HO long block (fell into one for pennies by a stroke of dumb luck)
No emissions (1978 Mustang II)
Weiand 289 dual-quad tunnel ram intake
Sync'd Holley 390 cfm vacuum-secondary carbs
Hedman headers to twin pipes with turbo mufflers
Duraspark ignition
(EDIT: Built C4 w/ shift kit)

I'm already running a built 302 with the dual-quad tunnel ram setup; that much works. I'm thinking to swap in a cam, bolt on the intake & carb towers, and drop the HO in. Cheap and nasty.

Questions:

- What cam?

- Keep the '86 HO heads (ported), or use the '66 289 Hi-Po heads I'm already running? (Buying new heads is not an option at this time.)

- Any idea what kind of flywheel peak HP this setup would generate? (I hate that question, too; but I can't find any reference to this idea anywhere. Maybe that should tell me something.)

- Will the mechanical fuel pump I'm running on my 302 be enough?
