That looks more like a 351w bored/stroked to 427 to me Rene...... but you refer to the transaxle as a Tremec 6 speed?---- is that correct???
Sir, have a rousch 427IR / RBT-ZF setup in my CAV, sn 102.
The Roush 427s are not big blocks, they are stroker Winsdor small blocks. Great motors, but not 427 farm engines.
Dave,I can't tell enough from the pic but believe that is indeed a Roush FE 427. Roush does offer an FE 427 engine as well as the 351 based version. They offer it in carbed or injected versions. I would side with the FE suggestion. I have had some in depth discussions with the Roush folks about their FE engines, they offer cast iron and aluminum versions. I can say that the aluminum version is based on the Shelby block, but there seemed to be some disagreement about who's iron block was used. The maker of the iron block seemed to take that very personally and resulted in some prolonged heated discussions following my conversations with both.
Now... Cal has a Windsor based 427 not an FE.
Ron,
I spent the Carlisle weekend sharing space with Roush and they indeed had a 427 alloy "Farm Engine" on a stand there.
I knew it was a Genesis block but when a Roush salesman denied it, while set up within 10 yards of the Genesis booth, a fist fight nearly broke out. The Roush guy had made several disparaging comments, including that they were junk, and the owner of Genesis went ballistic. It seems he does all the block machine work for Roush, from his comments pretty cheaply, and was pretty incensed.Dave
The iron block Roush use for their FE is the Genesis, Ford Motorsport used to do some crate engines using the same block but gave up due to supply problems.

Enlarge the pic up to 400%, definitely Windsor... the two vertical bolts in center of intake manifold between cyls 2&3 are just visible plus if it was an FE the spark plugs for 2&3 would be paired between those header pipes, they are not. FE header pipes would bolt up @ approx 45° from vertical, those are as per Windsor, just a few degrees off vertical.
