Samba, to be honest with you...I looked very seriously at both the 4.6 and 5.4 ford engines prior to investing in the L76.

The are both great engines........ but they are huge. The 5.4 is also exceptionally heavy.

I could have squeezed the 4.6 into the RMC engine bay given that I had already performed surgery to my footboxes. But it would have left little room to get to things like spark plugs and to make any sort of decent headers without bending up the pipes too tight.

I believe there are a few of the 4.6 engines installed (check out Blair on here) and a couple of 5.4's down south, but to me the headaches to make them fit was just not worth it.

There was also the possibly of upgrading performance in the future. To put a cam in the GM's is one cam.....not so fords.

The list goes on......however, these were only my deliberations and would/could be totally different to some others.

Having said that.....believe me, I know the anguish you are going thru. I have a ford 302, a ford 5Ltr, and a 351W in the shed all of which fitted the RMC beautifully.

In the end the authorities beat me with EPA requirments.
