I made block off plates out of stainless to fit the felpro gaskets. Laser cut to drop right into the intake gasket. Have extras if anyone is interested. Also EGR block off plates.

I would pack the hole with a wadded up paper towel and tap it for a pipe plug, probably 3/4 NPT. Get out your calipers and see what size hole you have and maybe the tap will work with the hole that’s...

FrankieTA,

I will post a picture again of what I measured on my 73 455 block with my cam, and a copy of my cam card.

I do not believe a custom base circle is necessary unless your block has...

Backdrive on manual trans only runs the reverse lights and letting the key out.

The factory put the 'neutral safety & backup light' combo switch on top of the column, but manual trans cars only used the backup light circuit.

Your 'neutral safety' switch on a manual trans car...

That is what I did with mine - just left it in park.

Dataway,

I agree with the nut issue. It would probably never have an issue, but I am supplying a bolt long enough to double nut it. That should be the final fix in these things.

true - though the issue with the bolt head is it is perceived it can come loose whereas in reality that is highly unlikely.

Scarebird,

Another option in lieu of the tube is to have a laser cut 3/16" dogbone on the underside of the lifter bore. This would have a flathead bolt inserted and welded perpendicular - it would go up as the...

Perhaps a press in sleeve to enhance control of the bolt's movement.
