Project 3400 Roller Cam Block (Page 8/82)

I kept the summit rockers and it revs fine.

As for a lower CR...you might try using stock 3.4 pistons but having material removed from the head. You could go with the pistons made for aluminum heads but that would put you in the low-mid 7's. That's ok, just crank up the boost to make up for it.

1 problem right now.
Coolant leaks out through the timing cover. I suspect that the hole that needs to be plugged on newer blocks was never plugged. Does anyone have pics of this hole?

Thanks!

There's a bypass hole in the Fiero timing cover that needs to be plugged. There is just an open cavity in the 3400 block behind that hole you see plugged in the timing cover. I drilled a 1/8" hole in the edge of the thermostat at act as a pressure bypass.

Met the owner at a show in Pomona a couple months ago. I may still have his card or brochure. Otherwise, I think West Coast Fiero sells their products.

It's on the road and running.
I got a 2.5" bullet muffler where the cat would be now but after that I have the stock exhaust mated to it for now.
I have a stange transmission noise, roughness. I got to check the fluids today.

I'm waiting for a chip from DarthFiero. Seems to have lots of torque and no top end. I'm hoping the chip will fix that.
The bonehead mechanic had snipped the Dakota Digital unit....for absolutely no reason. Archie emailed me instructions on how to get that hooked up so that is done.
Tachometer is not working, nor is cruise control right now.

The tranny noise worries me. No noise when I push down on the clutch. If it was the throw out bearing, there would be noise when I push down on the clutch. If the crook sabotaged my speedo, who knows what else he did.

Stupid question - how do I check the fluid level of the F40?
