Hey folks, building a 69 Fairlane Cobra formal roof clone. I have a 428 that was built for another car; intended engine mission has changed. I'll list out engine/car specs and we can go from there.
1. First off car; 69 Fairlane formal roof, C6 auto basically stock, 3.89 rear. Probably my last resto due to health.
2. Engine; 428 service block .030 over, Lemans rods, Scat crank, Probe pistons, XE274 Cam, C6AE-R heads with appropriate CJ mods including drilled for 16 bolts. Milodon deep sump pan, Holley street Dominator intake, 3310-1 Holley 780........which I really don't care for. Oh, forgot, 75 cc chambers in heads, Probe pistons -16 cc version. Was suppose to be around 9.6:1 compression.
3. This engine was built nearly ten years ago for a 69 Mustang 4spd car with 4.30 rear. As you can tell by date, life, health and a thousand other things can get in the way.
4. New mission with regard to Fairlane; car must behave.......absolutely must! With my health, wife will probably be driving more than myself. Good idle a must, decent overall manners a must, will have cast iron exhaust manifolds (CJ) and full exhaust. Power brakes a must, etc.
5. I realize what I am giving up here.......at least to an extent to how it was built. Things just change, I need this. I am concerned about cam? I think it will be lopey? I think idle quality will be sacrificed. I am not as concerned about current intake, but wonder if I don't gain anything from something like an Edelbrock RPM?
6. Would appreciate any thoughts on this build? I'd rather make changes now than later.
7. I appreciate this forum very much! Thanks for any opinions, advice, etc!
