Those seem like awesome times for the power... Low 9's in a 550hpish car?

F1C YA

Saw this car running on friday....looks & sounds nasty!

Yeah it's a powerglide with a fairly loose converter. A loose unlocked converter will always dyno less on a chassis dyno than it is actually putting out.

FWIW- The MPH and race weight says it's making 687HP. The ET is all that really matters to us.

Is it "Street Friendly" ?

Sounds like a sweet setup..

It's very street friendly as far as the idle and driving manners. It actually runs more stable than most of the bigger H/C guys that DD their cars.

We race too much these days to swap back and forth to and from street trim every week or so. It may make a few GTGs this next year, but we don't plan on doing a lot of street driving.

what's street trim...taking off the fire jacket and helmet?

TXCAMSS

iTrader: (60)

LOL.

It's funny you say that. My wife rides me all the time saying....just swap the tires. That's about it really.

You have obviously been there and done that. I love your your car man!

man o man. you said it was gonna rock, and it rocks and rolls!
generalization on the cam 250's 260's ?
insane.

258/262 Comp Cam custom grind. It pulls like a locomotive.

We have just barely scratched the surface. We haven't really had a chance to put the torque converter to the test yet.

Let us get a good hard pass on her and then we'll know what she's capable of.

I put it in the other thread but again cam specs are less important than the rest of the combo in valvetrain and setup etc. LS1tech is the most cam spec crazy place on the net and that's partly why some of these guys are not any faster since all they work on is cam specs! BTW I am not referring to you directly TJ but rather just the idea that the first thing people always ask is "what cam specs" and they hardly matter compared to a lot of "other" specs.

Nice....thats how it should be. Congrats again....think back 10-15 years ago. 9.50's at over 140 on pumpgas with no power adder...things are sure changing.

Shut your trap and give us the cam specs.

Let's go to Gringos.

racer7088

Cam specs are just one little part of the whole deal is what I am saying. It's important too but not the end all "spec" that matters or anything. I could have probably went with half a dozen different cam specs to get us to where this engine is at right now. It's a good combination of OEM block and parts to get some inches and then to feed them so that it makes more power and at hydraulic roller rpm levels is what it is.

But yes Gringos sounds really good right now Ben!

I think you are right Erik, too many people bastardize the valve train not knowing what it does to the overall performance of the valve train. It's not whats going on at the cam, its whats going on at the valve that counts. Incorrect valve train geometry can ruin what otherwise is a good cam grind.

What gear and rear tires are you running these days? Nice shakedown passes!

TXCAMSS

We are running 4.11s out back and have 2 sets of tires we swap off from depending on track and ET needed. One set are the Hoosier 29x10.5W-15 and the other set are Hoosier 30x10.5-15 light weight radials. We may have to step down to 3.73s or 3.90s. We'll know more once we play with our shift points and get some good hard launches.

Sounds familiar...now that I'm putting a stroker back in the car after my rodbolt failure this spring, I am taking the 4.56's out from the Stock Internals set up, and tightening the converter up a bit...4.11's going back in. I also run the Hoosier radials, both in 9" and 10.5" lightweights, both 29.5" versions (vs. 29.9"). My new combo is a pumpgas 427. Take care. Dave

Wyatt, very few of those places are probably true engine builders but more just normal machine shops and there can be lots of headaches if you don't know what you are doing. It all depends on what you are doing with the engine. This 445 is a bracket racing / weekend warrior motor and so it can be a little more wild but it still runs on cheaper pump gas rather than expensive race gas and still has a hydraulic roller cam for no maintenance basically.

Thanks to everyone as well for the nice words. I'll be glad when James and Sheila can get back out there and dial this car in. I didn't expect it to be quite this fast but a lot of the credit also goes to the Day's and their work getting it down the track and also the help from Joe and Josh at LMR etc. getting it all together for them so fast so they could make a few passes before the track shut down.

completely understand. thats why i was only asking a vauge question.
thats a fast recipe for sure!
