Took the old 302 to the dyno today since installing my most recent cam from Ed Curtis @ FTI.
Just a little background on my previous setup - a previous cam from Ed (from an old combo with AFR 165 heads and a Cobra intake) with Trick Flow 190 11Rs, Holley SM2, 1-3/4 used MAC longtubes, summit universal 3" X-pipe. 4.10 gears, 80mm MAF and home-made 4 inch MAF. Even with the old mismatched cam, it put down 350/341 and ran 11.8 @ 116. Let me say from the get go, I made it clear that this car is driven a lot. It's no 500 mile/year show car or race car. It's made several trips across the midwest (I am near St. Louis) to Louisville, KY Des Moines, IA, it goes everywhere.
Told Ed what I wanted - a cam to take advantage of the induction and exhaust system I am using, with a broad powerband, and I let him know I am not afraid to rev my stock bottom end to 6700ish, give or take.
Below is the dyno sheet, I'm working on uploading the dyno video.
Don't mind the smoke in the video, just my 137k mile rear main seal that likes to make itself known when high RPMs are in order, spitting a little oil on my exhaust.
Only difference between the setup I mentioned above (before cam) and new is a new electric water pump, and of course the cam. The powerband is broad and fun, I am already making 300 ft-lbs of torque before 3k RPM, and this dyno run was only done once because you could hear in person (and sort of see the mini-dip it takes in the graph right before 6430 which is where peak power is) that I am likely experiencing valve float - I am on the stock springs that came with the head, out of the box, and the air/fuel log on my dyno run shows the 2 banks differing quite a bit and jumping all over the graph after 6400 rpms.
The heads are straight from the box 190 11Rs with 56cc chambers with no porting, and the lower intake of the SM2 essentially has light porting to help match the heads, and cleaned up casting flash in the upper. Also, when I say stock bottom end - I mean the oil pan has never even been off of the motor.
This car was bought as a bone stock 86 GT, and I installed all parts myself. There is no weight intentionally taken out of the car (stuff like aluminum heads/radiator lost some, as well as smog removal), and it has power steering, A/C, power windows and locks - in other words, it is the definition of a street car and the manners reflect this as well. It's a 1.5 hour drive to and from the tuner, and it purred like a kitten smoothly at 2,000 rpms on the interstate to (yes, even untuned) and from the appointment. I repeatedly beat the piss out of it on the way home when I had stretches of open road, and it just begs for more!
Can't wait to install a set of springs and go hunting for some 120mph trap speeds.
