Why? Look at the crap NHRA is making 9.90 or quicker cars do now. Then you have the price of Race gas.

Oh, I'm not done. There are more hyd roller cam profiles I'm working with.

Working on after this with a cam only change. Nice thing about a hyd roller no need to replace the lifters with the cam.
If I can make 700hp with a hyd roller, unported CV-1 heads and over the counter BASIC parts ..................... why would I need a solid roller for street use and 93 True octane available to anyone on PUMP GAS?

RPM!

[PONTIAC DUDE]

Motor daddy. Here's one for ya. You like to do the math deal.

How much faster would my car be going from a 1.80 powerglide to a T-400.

3450lbs with stock suspension.

The engine really lugs down on the shift. Leave at 4200 (on a prepped track) 3800 on a decent track. Shift at 6500 and drops to 4800 and then holds at 5000 till it drives thru the 10" tight nitrous converter.

"Holds at 5,000" is not a good thing. That's a lower HP than you could be "holding at."

Ask Lynn how he does it, he'll tell ya. HP is what wins races. Your engine should be making more power at 6500 than at 5000 RPM. Why would you want to "hold it" at the lower RPM of 5,000?

If performance is the goal may I suggest more gear and more RPM? (a set of solid rollers would go nice with that extra RPM )

[gtofreek]

He said it stays at 5000 until "it drives through the converter" In other words, the conerter is stalling to 5000 rpm, when car speed exceeds what 5000 rpm will run it at, the engine will start gaining in rpm[driving through the converter].

He needs a different converter not more rpm or a different cam, MD.

its waiting for those heavy lifters to catch up

Agreed, a converter change would help his situation, but overall, REAL performance gains will be realized by keeping the engine in the highest average HP range. Ken's Power range with those CV1's and what, 515 cubes? What do the heads generally flow? Tom, how many HP are Ken's heads capable of producing?

[Cliff R]

"10.16@132 thru the traps at 6800 rpm. shifting at 6500. 3450 lbs, stock suspension, DR's with a Powerglide. LOL."

Ken, nice runs, what is the cid of the engine and do you have dyno numbers for it?

Just curious as Rich Roup's 505 runs 10.18 @ 132mph at the same weight. The engine is a high compression KRE block with high port heads (unported), with a pretty big solid roller cam.....Cliff

[PONTIAC DUDE]

535cu.in. CV-1 unported heads. flow around 380 max. Unported out of the box intake. Started porting the intake this afternoon. Have picks posted somewhere on here or PZ very very restricive. Hyd roller in the 260 range with .650 lift.
Gonna find out what the intake clean up does.

I think if i went back to a T-400 and the right converter with no other changes it would dropped right into the 9's.

It was also 94 degrees and muggy that Thusday early evening when i made those passes. Going home at 10 pm it was 84 degrees. It's been brutal lately. And only May!!!!!
From the combo and ET/mph, weather with a miss matched drivetrain left over from my nitrous days. Figure around 650hp. 93 Sunoco pump gas.

Did ya get that other carb? I need it .......... yesterday. LOL.

[Cliff R]

Ken, that's a pretty close estimate. Rich's motor just dyno'd at 660hp. Carb is in the works someplace.....Cliff

[n2ogpsj462]

would anyone other than us consider 6800 "RPM-ing" ? HA. Ken how are you with turbo profiles? your reputation speaks for itself with nitrous and SC cams but have you dabled with turbo grinds? im trying this 2802 on for budget reason but a hyd roller is def an upgrade for the fall.

[Ken -Ace- Brewer]

From my math the heads are capable of 810 hp. Good work Ken those are some impresive times!

And according to Wallace racing calculator:

"Your ET / MPH computed from your vehicle weight of 3450 pounds and HP of 810 is 9.44 seconds and MPH of 141.90 MPH."

[slowbird]

Ken havent you run 9s already with a hyd roller? For some reason I thought you had, maybe with N2O you did or I could be wrong?

[Silver Judge]

Imagine some dyno tuning and testing here, holy crap !


Running just shy of the 9's right out of the box is pretty impressive for a pump gas car in crappy conditions, these CV1 heads are badass! I say good job PontiacDude!

What carb are you running ?
With that many CFM, am I the only one that thinks it's time for something like a really well tuned 1250 or 1350 CFM dominator, that torque monster needs fuel, right ? !

And good luck getting it to hook too

[Cliff R]

Don't expect monumental ET gains from a carb swap. Ken has been at this game for a while, and if you saw over a tenth with just a carb alone, I'd be really surprised. Cripe, I've got customers in the low 9's with the early small cfm q-jets.

I agree the ET/MPH is impressive, but again, I'm not the first bit surprised. I would fully expect Ken to be able to put together a 650hp engine in his sleep, and set up a car to effectively use the power.

We assembled Rich Roup's KRE supplied 505, and in Rich's warmed over 3400lb street car it went 10.18 @ 132 right out of the gate. That's with unported high port heads, and a very "basic" spinning assembly, Star Galaxy forged crank, Crower rods, Ross pistons, 270 something solid roller, Victor/Dominator, nothing exotic anyplace.

My crystal ball tells me Ken's going to show us some runs well into the 9's when he gets the whole deal ironed out!.......Cliff

[Motor Daddy]

I believe Ace's 810 HP estimate is darn close to what the heads are capable of producing.

According to Wallace racing calculator, Ken is making 652 HP at 132 MPH at 3450 lbs.

Again, the heads are capable of going [email protected] MPH at 3450 lbs. I can make over 800 HP on a dyno sim with the CV-1 heads stock flow.

[PITTSBURGH 64]

I'll believe in them once I see people putting 80,000-100,000 street miles on them. I put at least 15,000 on my car every season.
My 60919 with Johnson hyd's works just fine.... I've never been to the track but my set up must be running good because I totally dusted a new GTO at the local street races this week. Aren't those cars suppose to be fast?
