My son and I drive our Catalina to the track, let air out of the rear tires, and thrash it for all it's worth. Then put air in the rear tires and drive it home.

Goatracer, that is really cool. I can not deny your street tires in that case!

What is your combo?

68birdfreak, 66bonne, and goatless tell us what your combos are too.

Someone needs to post Jay ? combo too. The blue 74 bird that runs a 12 flat in the F.A.S.T. class.

My Lemans is just a very mild 455. Stock intake & Qjet, d-port heads, stock log manifolds, th400, 3.31 rear. The fanciest part in it is the hydraulic roller cam which I'm still dialing in. This past season I was running it advanced but I really don't need the bottom end with those little tires. For next season I'm going to see if running it straight up will pick up the top end. As it is now the car is a nice Sunday driver- put the top down, throw the kids in the back seat and go driving for hours.

The last time I had it out it ran a 13.13 @ 104.5 on 93 octane just like I drive it on the street... with those little G-70 14's on it. I think with some more tuning it'll get in the 12's. Oh yeah, it weighs 4100 lbs!

I'll let Jay tell you about his '74, but I will tell you it's a little more exotic than my car. He's got a LOT left in that car as he gets his new combo dialed in. He's run a best of 11.84 so far with it.

Well, here is what I ran before I killed it!

Factory 421 block and crank (4.128" x 4.00"), 11.4:1 cr, 6.625" Eagle rods, JE pistons, w/Butler steel 4-bolt caps.
Comp Extreme energy solid street roller 248/254 @ .050" on a 108 lsa and .600" net.
The heads are 62cc High ports that are in the 345 cfm neighborhood on a small bore, T&D 1.6 shaft rockers, and a Victor intake thats been welded, ported, and shot peened back to an stockish appearance with a Pro System Dominator on top.
I ran 1-7/8" Doug's headers, a Dr. Gas X-pipe, and a full length exhaust system. The converter is an ATI 8" treemaster (3100 foot brake) with a 200-4R trans. 4.11 gears and an Eaton posi in a 12-bolt housing end it off.
I run the origional stock front coil springs and sway bar with 12x shocks front and back. The rear suspension is the Dick Miller bolt on kit with a HRParts-N-stuff rear anti-sway bar. Tires at the time were M/T 295/65 drag radials at 17 psi (25 down the freeway).
The heads and intake are surely the trickest part of the combo. The rest of the car is pretty basic, but works well together as a package.

We did'nt dyno with old 248/254 cam, but the new UDHarold cam (263/269 @.050 and .650" net) produced 670 hp and 560 lbs. of torque down at Westech a few months ago. I feel that the old cam was in the 625-630 range. Did'nt get a chance to see how the new cam worked at the track before I wounded the shortblock. Now the High Ports and 263/269 cam are going to reside atop a 496" IAII shortblock at 10.8:1 cr.
Should be interesting.
