Yes it works fine but you will need to change your valve springs.

Why did you change your rocker arms when you put a cam in? I'm not seeing the logic here.

Were 85s roller motors anyhow? Im thinking they started rollers in mid 85 but I cant remember? Im like Darrell though. Roller or not. Why would you change the rocker arms? And I still dont understand the reason for putting a larger cam in a stock motor? Like mentioned before. That works well for a chevy but the 5.0 cam is plenty more than what alot of ppl give it credit for.

I put a new E303 in my 2000-built FMS 302 short block, with rebuilt stock heads and have run it for 2 years with no problems - no noise and good power. I think the key is to not use springs with 140,000 miles on them. Why would you need to change the rockers, for a E303?

A show car: 5 year resto-mod compl. Jan, 2006. Big wins: Best Engine, 2007 FFW - Belle Rose, First Place, Modified - 2008 Biloxi Mustang Show, & Best of Show, 2008 FFW - Belle Rose. Not a total candy a$$. I like to get on it, too.

Don't use stock springs on those stock heads or you will be sorry.

Its not an opinion. When the spring you are using has less travel than the lift of the camshaft, things are going to break. You can either spend $80 now and put the correct springs in for the cam you are using or spend $800 or so later repairing all of the damage.

Here is one example. If you shop around you can probably find something cheaper. Basically what you need is a diameter that is 1.400 to 1.47 with an installed height of 1.78-1.800 and spring pressure like what is listed for this spring.

I'd recomend new valve locks too since you are in there but they are not necessary. Just a piece of mind.

Thank you sir. I need to buy a 255 and a crank pulley for my set up still. If I don't get these gt40p's I think I'll just invest the 65 bucks.
