It's a crappy combo that I put together when I was young and didn't know any better.  Shortblock is a .060 over 289 (never overheats), stock crank, factory rods with larger ARP bolts (should have just stayed stock size with the ARP's since they are very strong), cast pistons, HV oil pump, and balanced. 

The heads are factory '66 289 heads that have screw in studs, no guide plates, mildly ported, stock diameter 1.78" intake valves with a three angle valve job, and stock diameter 1.45" exhaust valves with 2(?) angle valve job.  Wound up with a pathetic 9:1 compression when I had wanted closer to 10:1.  Good thing is that it runs on 87 with full timing.

Intakes have been a Weiand Stealth, Vic Jr., and Vic Jr. with runner extensions welded in (not ported).  The Weiand Strealth and modified Vic Jr. run just about identicle at the track.  The stock Vic Jr. was a dog down low and is now stronger than the Stealth down low with the extensions.  The carb is an annular booster 850 Holley dp with choke horn milled, 950 baseplate, and a bunch of majic the builder performed to make it run well on a little 289.  I walked in asking him to build a 750 dp for it so I could throw it on a better build in the future.  Got a call form him later asking me if I wanted to see what my car could do with a real carb.  Picked up about 5.5mph in the 1/4 mile at the track over the old tuned 625 Carter AFB.

The cam is a reproduction of the old hipo solid flat tappet grind.  .477 lift, 228 duration at .050 lift, on a 114 lsa.  Run it with 1.7 ratio rocker arms which make it a little bigger.  It's a rather small out of date cam that is even smaller when you account for the .018" hot lash required.  Picked this cam because at the time the motor was going into a '66 and the smog cut off was '65.  Though it would pass since it was a stock cam and it did.  Would not choose the same cam again even though it has done better than expected.

The exhaust is regular old 1 5/8" Hooker headers, 3" collector, into 2 1/4" Flowmater two chambers with H pipe.

Rest of it is a t5z, limited slip 8" rear with 4.11's (not holding up well these days), and slicks for the track.  Have a beefy 9" with 4.30's sitting in the garage waiting to go in.

In my '65 fastback it has run a best of 13.32 at 102 mph in the 1/4 mile with a 1.84 60ft.  Our local track (LACR) is at elevation.  The corrected times are 12.88 at 105.1.  Everyone I've spoke with says the correction is fairly accurate to a little conservative so I'm very confident it should run high 12's at sea level.  If not I'll ditch the flex fan and drop the exhaust.  Brother-in-law ran 13.2's and 13.3's in a Camaero at that track and ran 12.7's all day at a sea level track that is now gone (Carlsbad).

Strange combo that I wouldn't do the same again.  It somehow has turned out alright and runs better than the high 13's I'd hoped it would do.

Work in progress:

Stock bottom 289
Canfield 170cc 18* heads
Jay Allen custom SFT cam
Stealth intake
FPA 1 5/8, 1 3/4 step headers
2 1/4" exhaust
Holley 650 DP

SHOULD make 310-320 hp @ 5900 at the wheels, 300 ft lbs @ 4300 and 14" of vacuum at idle. Going into a 68 convertible mustang, T5, 3.40 trac-loc. The car won't go to the track, but should be fun to drive!

Now I say work in progress because I ordered the heads and cam around Memorial Day and I still won't have the heads before Labor Day.
Canfield did not have rough castings to make the 170 heads until last week. I should be getting them soon.  In all fairness Jay is a straight up guy and offered to refund my $$ for the heads. Since I hadn't pulled the motor, I decided to stick it out. No complaints, but if I had it to do over, I would have ordered the 195 heads and had Jay grind a cam for them. Just been using the time to learn all I can before I open the motor. Glad I found this site.

A good solid lifter cam will be worth a LOT in that combo...  It's going to want to rev close to 7k, and there's a lot to gain with a solid at that rpm range.

Good Luck!

REALLY fun sounding, old school combo!

Wow this is an old thread!  I haven't had the combo I wrote about above for some years now.

Here's my combo which will be going together this winter:
.030 over 289 stock bottom end, cast crank, stock rods, forged pistons
AFR 185 heads
FRPP M6250-A351 hydraulic flat tappet cam (got it brand new for free with lifters)
Edelbrock Airgap intake with 1 inch open spacer

Sounds like it's a pretty good 289 build. Smiley  Like Mike said, you could do much better with the cam.  But, it will get you up and running. 

One thing to be mindful of building a 289 is compression.  There just isn't enough stroke to build decent compression with your standard flat top pistons with large valve reliefs, 58 + cc combustion chambers, and the typical assembly with pistons down in the bore.  I went with a 54cc chamber cylinder head and purposely had the deck milled so the Probe SRS flat top pistons where around .005 above deck.  Always run on 91 pump gas.

First and only trip with the faceplated straight cut gears in the T5 and port work to the heads and intake.  https://www.youtube.com/watch?v=ht10NXmZcvw

I need other things in life to slow down right now so I have time to fix a couple issues with the car and get back to driving and racing it.

I'm with them. A different cam should definitely be considered.

Due to the engines decently sized cylinder heads and induction, it won't need much cam to be able to pull higher than you want to turn it.

With the small cubic inches, the cam will likely want a much larger converter to be happy.
