This post covers mine (Mustangaroo) latest dyno and my son's (65Stang) rebuild of his 200 and Aussie 2V project!
Well I did put it on the Dyno last week, after installing the Holley 500 (358 cfm) carb! It just feels much better, take off and WOT, just feels like much more power! But on the Dyno it only showed up as 2 hp gain! I am now at 107 HP to the rear wheels or about 135 at the flywheel. Remember this is a stock short block 9.5:1 CR, Stock Ford Cam, Aussie 2V head, stock valves 1.6 Rockers, NO PORTING or POLISHING!
The Dyno Shop thought I should add the 40,000 volt coil to my Pertronix setup thinking that and a larger spark gap may help? I plan on doing this in the next few weeks and then Dyno again when I take my Son's (using "65Stang" on Fordsix.com) Mustang to the Dyno Shop!
He is going to start his 200 up today for the first time since rebuilding!
Here's his rebuild list, remember this is a daily driver that will be driving about 50 miles per day! So we weren't looking for the most HP gain that was possible in the 200 or aussie head!
Engine rotating assembly balanced
Bored .040 over
Decked to .000 (milled .030)
HSC Flat Top Pistons
CR should be 9.5:1
ISKY 256 cam, Lifters and Springs (RPM range 1000-4800)
Stock Rocker Arm From Aussie head (1.57 Ratio)
Aussie 2V 250 head
3 Angle valve job, NO port No Polish!
headers six into two (possibly Hooker- NOS)
Holley 5200 (my old one) Good Performance Great gas Mileage!
Pertonix, stock coil
Looking for 135 HP or about 170 at the Flywheel?
We'll post the result's of the Dyno and pictures of the new engine setup!
For those interested the Aussie 2V bolted on and fit very nicely into his 65 Mustang with room to spare!
Here's pictures of 65Stang's project, it was installed yesterday and will start today!
