History 64/65 Comets old drag cars lets see pictures

Sounding good Dale and goodluck in Bakersfield.
Roger

 

I run the same gearset, yes. At both 1/8th and 1/4 mile

 

The new Windsor is just about finished, and will go onto the run stand in a week or so. On the conservative side, 560-580 h.p. with a current weight of 3,000 lbs. The mighty little 289 will be finding a new home soon.

 

Dale;that should make the "ROCKET" run hard!!!You might get close enough to my old Comet so that when it sheds parts they can bounce off of your Comet!!!!Did Ben get you any HP info on the 289? ROY.

 

Good guess is about 425-430 h.p. What continues to haunt me is the fact I still leave the line at 2,400 rpms.....

 

Get rid of that slush box and put a 4-speed in there,then you can leave at ANY RPM you want!!! Plus they are WAAAAAAY more fun to drive!!! ROY.

 

Dale what is the 289 going into?? Are you motor swapping before the march meet?

 

I can't imagine the 66 funny car used any chassis from the 64 or 65, it was a round tube chassis.

I think the 64 car started out as an AFX car. It was run in AFX before the supercharger went on, or was there a second Sachs 64 AFX'er?

 

Tom;there were two Sachs and Sons 64 Comets.You are correct in that the 66 Comet Funny Cars had dual round tube Logghe[spelling?] chassis. ROY.

 

I have a little '63 Hillman Husky, to be set on a full chassis frame. It should be a very nice compliment to the car.

I'll be lucky to have the new powerplant in before the end of the year. Really no rush, so I want to make some safety upgrades like 31 spline axles, additional rollbars, etc...

 

Dale;
I have a couple Questions. Are you still running a more built up 289ci or going to 351w? Next are those 31 spline axles running with a spool? If you are, make sure they are not Ford axles "Resplined" they will twist and brake. So buy good After Market Racing axles. When are you going to put the Third Pedal in the car. Good Luck with the Rocket. -AFX DAVE-

 

The Hillman can be a TERROR of the local streets!!! Trying to get my Comet ready for the March Meet,need to finish the engine and get it back into the car,then install the new fuel system!! ROY.

 

When the Winsdor gets installed, the rear differential will be taken apart. I'm going to set aside the 28 spline hardware (axles, Detroit Locker) and install a spool with aftermarket 31 spline axles, most likely Summers Brothers, as they are close by my shop, and are trying to come back into the drag racing scene after a hiatus from it. Someone I know has several 31- spline gearsets on spools and center sections, that I can use to figure out the right combination . This is why, for me at least, it will take some time to make the transition to the new engine platform.

 

I need to tap into the great minds on this thread...I want to get an electric fuel pump to feed the 289.It is bored .030 over with 12.5 to 1 compression ratio...solid lifter cam with 312 advertised duration and.534 lift...heads are ported and polished with 1.94 intake and 1.60 exhaust valves...hi-rise single plane manifold with a modified Holley 4150 series 750 CFM carburetor. What PSI and GPH would you recommend? The car is setup for the track but occasionally driven on the street...Thanks.

 

This is what I use for my dual quad 302 11.1. I regulate it to 5psi and have 3/8 fuel line from front to back. Plugs are medium brown and have a nice burn pattern. I can show you how I mounted it and the filter if you want... Mechanical pumps are more reliable, but if you make the choice to go electric, this one works great for me

Last week was the first passes with the new and upgraded fuel system in my Comet. Before we went to Japan, the car showed dangerously lean conditions. Pure white plugs, even after we jumped up two jet sizes all the way around. It told us the mechanical pump was not keeping up with the needs of the engine. I ran a Holley mechanical fuel pump, and a 3/8th's line. Now, we are getting a safer fat tune, one that I should be able to play with jetting, using a -8 line, and a Holley electric "blue" pump, regulator pressure set at 6.5 p.s.i. I knew we were on to the right thing, as the float levels immediately needed adjustment. I did not feel like running an electric for so long, but now realize that when you step up the performance, its needed...

 

I learned my lesson on mechanical pumps back in the 70s!! I was running a Holley NASCAR spec mechanical pump,it would not supply enough fuel at the 'HIT' for my 289,4-Speed.I went to a Carter Electric pump feeding the Holley Mechanical for a few years before I redid the whole fuel system. ROY.

 

Installed the new Moroso electric water pump drive. That ought to stop the 8,500 rpm cavitation in the pump......I hope... Those are badass little gizmos!

 

1000 posts! Congratulations ! Roy runs one of those and I did last October at the CHRR. They are cool pumps , but man they come with some cheesy brackets. Personal preference, I just did not like it, I dunno why.. It cooled decent.. I went to an electric waterpump from CVR and an electric fan from Derale... The cooling is much greater for my application and with just the pump alone idling for 20 minutes I was able to keep it at 160... When I kick on that lil fan, it's like a whirlwind and you can watch the temp drop on the gauge..

 

What happens if I increase the rocker arm ratio on an engine?For example,if I increase the ratio from 1.5 to 1.6 does that increase the lift?And are there any drawbacks to doing this?Do I have to compensate for the increased ratio?Does the cam need to be adjusted,or anything else?I'm full of questions about rocker arm ratio...

 

I need to look at your set-up in depth, Mike. Since we'll hopefully be side-by-side, it'll be nice to compare notes, along with Roy's full-race set-up. This is what I cobbled together:

 

You will get an increase in lift, by a marginal amount. We did a test with Chevy High Performance a few years back, on one of my engines, increasing from a 1.5 to a 1.6 netted a 6 h.p. gain only on intake side. Small, but there...

 

Steve;one thing you need to check is piston to valve clearance,especially if it was close before the rocker swap.Valve lash should be the same,you may want to play with ignition timing too. ROY.

I remember seeing older pictures of this car somewhere in this thread.

 

Roy, I hope im not bothering you, what did it take to put your 351c in your comet? did you have any trouble with the fire wall hitting the scatter? is there any big issues doing this? would like to see some pictures....thanks mike

 

"Bother ROY"....I don't think that's possible.The man's answered any question I've ever asked him He's a boatload of knowledge There is a decent pic of his engine compartment in this thread post#4708
Thanx Roy
Myron_

 

Myron;your check is in the mail!!!!! Mike;I have a 351Windsor in my Comet,from the top of the bell housing to the top of the front cover down they are the same as a 289/302,so NO,I didn't have to touch the firewall.A 351W will even fit without notching the shock towers but notching them makes header building easier.The biggest hurdle I ran into was headers,as I could not find any off the shelf,so I built a set of 36" long,13/4" to 17/8" stepped primaries to 31/2"collectors,and the Edelbrock intake is so tall I can not run a spacer or an air cleaner.A 351C will also fit as the main block structures are also the same as a 289/302. ROY.

 

Myron;I had to go look at post 4708,that is with the old 289 based 352" stroker.A hand grenade with the pin pulled,never new when it would go BANG!!!!! ROY.

 

oh ok thanks, for some reason I was thinking you were running a Cleveland. mike
