I haven't been able to locate a manual for my Electra yet and I find myself in the middle of a manifold/carb swap and I'm doing the lifters at the same time. I need the torque settings (and sequence - just to be sure) of the intake/head bolt and the rocker assembly to head bolts. Can anyone help please? Bill
Torque specs for both the intake manifold to head and the rocker shaft to head are 25-35 ft lbs. The usual sequence for the intake manifold is to start near the middle of one side, then the other side, come back to the ends on the first side, then the ends on the other. In other words start in the middle and alternate sides as you work your way to the ends. Jerome
Jerome, you're a life saver . Thanks a lot. Is there any specific order that the rocker assembly bolts should be tightened down as well? Thanks again. Bill P.S. Is that 25 then 35 or anywhere between 25 and 35?
According to the manual it would be at least 25 but no more than 35 ft. lbs. I would do it as you indicated, maybe 20 then 25 then 30 then 35. With the rocker shafts I would also pick one of the middle bolts then alternate out to the ends. The manual recommends to get good torque readings that the bolts be clean and lightly lubricated. I just use a few drop of motor oil from an old manual oiler. Jerome
Here's a few pics of the job so far. They where taken 10 minutes ago (11:45am). Below are 2 photos showing the diffence between a standard 1966 square bore 401 intake manifold and a 1966 425ci spread bore manifold. The larger secondary inlet of the spreadbore quadrajets can clearly be seen and is the reason why I am putting a 425 Spreadbore on my 401. Along with a NOS '76 Quadrajet it should make for a smooth and powerful ride. This is me getting a sore back tonight. If anyone wants more photos I have plenty as I am going in to replace the lifters as well. Bill
