79 Foxbody Mustang FE 445

MrRupp:
Well we finally got the mustang on the track this year. Two years ago we threw a old wore out 410 with cobra jet heads and comp 292 cam in it and went racing. Our best time was a 12.89 @ 105 mph, which isn't bad for Bandimere.  So naturally we needed to go faster so we got a hold of Brent and bought a stroker kit and stroke it to 445. Brent had a custom cam ground for us. We put C4AE-G heads ported with 2.125 intake and 1.71 exhaust valves. First time out she ran 11.87 @ 114 mph, but broke a rocker arm. So we up graded everything in the top end including the rocker geometry.We went with P.O.P everything including there roller rockers. So last weekend was All Ford fun Day and our best time was 11.58 @ 117 mph. Were still taking easy on things and only shifting at 6000, but soon as we get her broke in will turn it up to 6500. That's the rpm the engine is built to run "hopefully."

Sounds like a fun car. I'll admit I'm a little jealous of the room you have in the engine compartment of the Fox body.  :)

I'm curious what rocker arm you broke? Aftermarket, stock? It's unusual to hear of a broken rocker arm on a mild FE.

MrRupp:
The rocker we was a stock ford adjustable. It broke right behind the adjuster. The cam is lifting .660 on the exhaust and .640 on the intake. I think the biggest problem was our geometry . We ran it 5 runs last weekend and it ran pretty good. I'm going get in the shop and pull the valve covers and see how things look.

As many of you may know, I first swapped a FE engine into my 78 Fairmont over 30 years ago, and although there certainly is more room between the shock towers on a "FOX" platform, so getting a wrench on the spark plugs or headers is pretty easy, compared to a 67-70 Mustang/Cougar, or 66-69 Fairlane/Torino/Comet, things get really tight underneath. The FOX has large, angled lower control arms that really eat up the space for headers and oil pan. A modern aftermarket tubular K member would free up a lot of space, but they did not exist when my car was first put together.  Front coil overs and tube lower control arms would offer even more space, although personally I don`t like the idea of a nose heavy, wheelstanding FOX putting all that stress thru the very thin sheet metal strut towers , which were never designed to carry the cars weight there.

Congrats Mr Rupp it’s always nice to get something together and have a little success. Keep up the good work. It’s funny I was just thinking a few days ago ( is nobody bringing there car to the track this year?).
