I have an 83 Mustang and I'm looking to do something different than the usual 302 4v. It has a 68 302 4V w solid cam, built T5 with 373 gears. totally old school! I have purchased FMS Z2 cylinder heads i was going to put on that motor but I think I would like to do a high compression 427 small block on E85. I have a 5 figure budget for this project and I would appreciate any advice on injection , ignition systems. Thank you.
