@grog are you going DOHC in your car?? I seen @XR7-4.6 had to cut a lil bit of the underwood to make it fit I believe, which I already chopped mine up haha. Maybe some time next year I’ll 4v swap my bird if things are better.
@XR7-4.6the only thing they did recommend is upgrading the roller followers to the ford GT because they handles the stresses better at higher RPM’s. What lifter/followers are you running in your 4v? I know you spoke to Todd Warren about it.
I actually only had to clearance the hood for the EGR valve to fit, it’s fully intact otherwise. There’s like 1/4” of clearance between the skin and the highest point of the manifold!
The Ford GT followers aren’t any stronger, the benefit of them is the smaller holes for the oil to bleed through from the lash adjusters, which both raises oil pressure(not that that’s really needed at high RPM with what modular oil pumps put out) but more importantly minimizes excess oil being dumped in the heads faster than it can drain back from them into the oil pan at sustained high RPM.
I’ve just got the OEM followers in mine for now, buying 32 of the things exceeds what I paid for the damn engine
