429 Thunder Jet

[mustangII460]

429 Thunder Jet is the same as the basic 460.

Ford put them in Lincoln and Torinos.

The Thunder Jet should have rail type rockers, as was the case for 68.

Not until the Cobra Jet in 1970 did canted valves, (Staggard rockers) come out. Both work good.

You can find good parts for rail type rockers. However high RPM suffers compared to canted valve design. But unless you build a roller motor, you wont lose much if any.

If you want a street tourqe monster they work great.

Personally,I would use them.

$200.00 for the used heads is a fair price.

Oops: I got a little ahead of myself on the valves/rockers. I wuz thinkin of another combonation.

Proof reading goes along way.

Anyway,thanks for the flame.
