Re: ford crate 521
We put a 514 in our vert and ran into some little issues.
1. Make sure you have a huge radiator. We are already 3" wider and minus the trans cooler with a Howes Racing Radiator and she runs 190-195. Way hotter with the stock rad. 2. If you use the March Performance pulley system you will have little to no clearance for the fan if you run a mechanical. Nothing that can't be remedied but it is an issue. 3. Hood clearance. We ended up putting a cowl induction scoop on because the hood wouldn't close with a high rise or medium rise manifold.
I don't think we had any other real problems.
