I know I am going to build at least one 409 this winter and this makes me want a blower.

Looks killer Brian!! Any luck finding a car for it yet??

I called on a rust free 60 impala 2 door hardtop, but it was sold already. Still on the lookout for a Willys. I called on one of those too, but it needed too much work.

If you use a 409 crank, 6.385" rods, and the KB pistons for 4" stroke/6.135" rods.....they would be the cheapest by far. Aren't they rated at 10.5:1? With the small chamber in a set of 333's I bet you could get close to that 9.5:1 without having to run too thick of a head gasket and killing quench completely.

Not sure but the 333 chamber should drop compression about 1/4 point. Doses anyone have experience on the effect of bigger piston to head clearance on blower motors? Too much on normaly asperated is supposed to lead to detonation???

I was told the tight quench still applies to a blown motor.

 

[Don Jacks]

Why wouldn't it,especially on todays junk,alcohol laden fuel?

 

[region rat]

I have some blower pistons and there is very little that counts as quench, since compression is so low. The 8 1/2's have a slight quench area.

 

[region rat]

The second set has really deep valve reliefs so the quench area is a little wider. I guess if it's needed, you could do the long slot valve relief like the old Jahns and make it deeper to have some quench.

Cool manifold,will be something to see for sure.

There is a '61 Biscayne with a blown W on Feebay right now. Thought you may want to see it for additional inspiration!

Damn it looks mean.
