BTW, the last time I weighed my car it tipped the scales at 4120 lbs. on Mason-Dixon's electronic scales. This was with me and 1/2 tank of gas on board, and at the time I weighed 360 lbs. so do the math, it's a HEAVY street car (and I don't help matters).

[Gach]

Well I just sat an eat two donuts, so if I'm not careful I'll weigh 400 lbs. I'm not sure what my car weighs, I weigh it twice, and got to different weights, first time was at a local sand and gravel, weigh 3320 lbs, but at Lebanon Valley it weighed 3250 lbs. Trying to get that weight down to 3100 lbs, pretty hard to do, a 70 Goat is real heavy to begain with. You did very well to run high 11's with
that weight.

KO,

I had Jess Miller's shop do some of my 428 and 455 work in the 80's and early 90's. Real fine work. I trust they could do that Block inspection that you described.

I can see a Gach-Inspired thread comming :

"the 1000 HP Poncho combo"

I just want to know the max rev to achieve any of these HP numbers above 700HP.


...STILL holding out for titanium connecting rods.

[Brian Baker]

Keep in mind I didn't get it into the 11's until I strapped on the bottle (150-HP shot). Even still, she's still good for 12.70's @ 106 in good air (only running a 3.23 gear too).

[Brian Baker]

sorry for the double post

[Gach]

½"........700 hp, what rpm. I tried to make 750 hp, with the last motor combo, I got a big disappointment. Here's the combo, Edelbrock heads, 320 cfm intake 260 cfm exhaust. 14.1 compression. Victor intake, 1050 Dominator, Comp roller 284/289 @ .050 694 lift, 110 lobesep. Dyno @ 694 hp right around 6400 rpms. 462 motor with 4.210 stroke. Torque was right around 640 lbs @ 4800 rpms. A 4" stroke would have been better. The Ram Air 4 headed motor made
640 hp with a little roller 265/265 @ .050 with only 640 lift cam, and made that hp at 6200 rpms. 610 lbs torque at 4800 rpms. Some thing is missing.

Brian, that is very impressive, 12.70's weighing over 4100 lbs.

[Gach]

Now when I used the combo from the guy from the west cost, with that little roller, and his heads, the thing made 610 hp, with no juice, on pump gas, and his CNC ported heads, 9.50 compression.With just changing heads and cam, using the CNC ported heads, and his recomened cam, putting them on the other 462 motor, we made 740 hp. So this tells me, it's all in the heads. We never go any flow sheets with the CNC ported heads, so I put them on a Super flow 600, and they flowed 340 intake, and 275 exhaust. The roller wasn't that big either.That was with 14.1 compression. It
made that power at 6500 rpms. But the new combo should be good for 1000 hp with the bottle, with no problem.

Why the juice, your just not going to make that kind of hp with out it. Maybe with bigger cubes, and a block your not afraid to hit with about 500- 600 hp shot.

[Gach]

The Wenzler heads do seem to flow better, and a set of those are also in the works, there not my heads. But they did need allot more work, the bare casting were very rough. I don't think the heart shape, really makes any diference, hey I may be wrong. My opinion with either head, you not going to see more then 800 hp, but your going to pay big bucks to get that, unless you do it in stages, little each year. Here's the other thing I've notice, those heads ( with the big flow numbers ) in bad air will drop 3-4 tenths. So when we hear these big hp numbers, it only happens maybe once or twice a year, but you can't make your claims off those numbers. What your really going to see this year. is
blower's, and nitrous.

Last trip to DeSoto, there was a guy running an early Cat with a 421. The announcer kept reminding everyone it was a Pontiac powered car, no BBC.

10.30s at 129 IIRC.....

What a ride!

Gach.....I have a couple of questions on that set of CNC heads. Were the pushrods moved over? What size intake valve? The flow you measured on the bench....I assume it was at 28", but at what lift?

[Gach]

Wow! that cranking for a 421, espically in a Cat, pretty heavy car.

[Gach]

Tom, yes the push rod was move over .150, and was measured @ 28". That was at 700 lift, with a 2.19 valve, and a 1.77 exhaust valve.
