Difference in 351W timing chain covers?

[DaveR]

I've seen prices range from $65 on E-bay to $135 for an FMS timing chain cover to fit a 351W. Is there any difference?

Remember some have provisions for a mechanical fuel pump and some do not. Also some covers are set up for reverse type water pumps,so be careful. Hope this helps

As Eric says, there are at least half a dozen different covers and all of them will bolt to your block. Here's a site to look at pics of a lot of the later ones.....

Another feature to consider in your selection is.....front sump pan or rear sump pan? (the dipstick is in a different location)

Eric,

I just need standard rotation with mech fuel pump boss.

Ed,

Does sump location affect timing cover choice? Do your Vic Sr. heads give you enough bottom end for street use? I'm planning to use a 3.50 rear since the Tremec is geared so low.

Eric,
The timing cover for the front sump has a boss with a drilled hole on the lower pass side of the cover for a press-in dipstick tube. Some of the rear sump covers have the boss, but not drilled. Some have no boss. If you have a rear sump the dip stick will go through a hole drilled in the block or, in some cases, into a fitting on the oil pan.

I run the same cam that comes in the FMS 393 crate motor. The motor is very streetable with a torque curve that feels virtually flat all the way to the shift light at 5700 RPM. I've been very pleased with the Vic Sr. heads so far.
With 3.50 gears, the Tremec gear ratios and the 408's torque you'll find little use for 1st gear, except maybe creeping along in stop-and-go traffic. I have 3.73's and I'd sure like to have a taller gear. This winter's project, maybe.
