So is it the general concensus around here that a custom intake will be needed to run fwd aluminum heads on a thirdgen 60* V6 ?

 

should beable to use the FWD intake, aslong as the upper section can be rotated 180 and still match intake runners. That is MOST of the fwd intakes

 

The FWD head are of a canted valve design, I dunno if the pistons have enought relief on a RWD block to accomodate them...

 

You can not just bolt the heads and go. 26.5cc combustion chambers vs 49.5cc

 

I just was asking because I noticed the 3.4 4th gen intake base looked to be a match for the fwd heads.

 

I haven't seen any pics of the 3.4 base intake... does anyone have any?

 

3.4 base looks almost identical to our 2.8/3.1.

Has extra sensor hole up front (thats plugged) and doesnt have the CSI hole in rear.

 

So, I'm guessing that you mean even if it were done, the compression ratio would be jacked up so high, the car wouldn't run?

 

the compression ratio would be over 11:1 with the aluminum heads. Their has been some one that has done it on a f-body just can't remember who though (think it was on a 4th gen). The problem I see with the gen III topend is distributor clearance on the lower manifold.

 

Raven did a Gen III top end in his 3.1 powered blazer... don't know where to find him anymore, though.

 

he went DIS with his though, so he diden't have any clearance issues with the distributor hitting the lower intake. he used the wiring harness and ECM form a 2.8 J-body and a home made crank trigger.
