Romeo vs. Windsor

delling3 · Nov 11, 2020

So, what is the best (easiest) way of knowing if you have a Romeo or Windsor 4.8 2V? I am finding conflicting information.

My car is a 1996. The VIN has an "X" as the eighth digit. From what I found on the LMR website, I take this to mean it has a Windsor motor. Is this correct?

Easiest way is counting the cam cover bolts. The Windsor’s have 13/14 bolts. The romeos have 11 I think. I don’t think the mustangs ever got Windsor npi engines.

Nope. They started windsors in 99

Good to know. I am getting ready to start tearing down the top end for a cam swap, and I was worried that the cam gears might be the pressed on type (Windsor). Knowing it's a Romeo eliminates that worry.

Most definitely bolt on cams.

Are you doing a teardown of the front too or just gonna slip them in?

Look for REP or WEP on the valve cover stickers

Tear down. Chains, guides, and tensioners, water pump. Swapping in a PI intake at the same time.

Agree with adding the heads. Pretty easy to find a set on fb or ebay.

Yeah! Im with these guys! Be sure to use mustang cams! Car runs like a mad man!!

Budget just doesn't allow the head swap. If I was going to go that route, I figure a couple hundred bucks for the heads, then the costs for a machine shop to do a clean up on the heads, head gaskets, bolts, and I am easily in for $600-$1000 just for the heads. I picked up a FRPP intake from PinkieT and a set of Bullet Cams for the NPI engine from OLD H2S. I am not sure what this will all add up to HP-wise, but I will have to be satisfied with this, cuz I got other things I want to spend money on.
